The experiment on oats transpired during the crop season 2021–2022 according to the split-plot design system of the full randomized complete block design (RCBD) with three replicates. The potassium element was in the chief ingredients in three concentrations (0, 10, and 20 g L-1). The genetic structures, secondary pieces, and results showed that the genetic appearance and environmental conditions under the three concentrations were positive and significant in all qualities. The natural and ecological manifestation analyses in laboratories showed complete, high, medium, and indirect effects in all features under study, with a varying percentage between spraying concentrations. With potassium, the qualities indicated a positive and valuable association with the raw protein of the grain summary of the plant at all levels and had notable indirect effects through some other characteristics.

In the conditions of Khoronk settlement of Armavir marz, Armenia, Helicoverpa armigera (syn. Chloridea armigera Hübner) and Spodoptera exigua (syn. Caradrina exigua Hübner) are the chief pests damaging the pepper plants in their larval stage. In crop season 2022, experiments on these pests in pepper fields tested the insecticides that mainly control the insects. The insecticides tested against Helicoverpa armigera and Spodoptera exigua included Eforia, Belt, Decis F-Lux, and Spintor. The Arrivo served as standard, and the experiment also had a control. As a result of the conducted research, the insecticides Belt, Decis F-Lux, and Eforia showed the highest biological and economic efficiency in controlling Helicoverpa armigera and Spodoptera exigua. The study also ran a biochemical analysis of the pepper harvest to know the effects of the applied insecticides on the peppers’ quality indicators.

Iron and zinc are essential micronutrients for human growth, development, and immune system maintenance. Iron (Fe) and zinc (Zn) are necessary for psychomotor development, sustained physical activity and work capacity, infection resistance, and various metabolic functions. Currently, rice, preferred for being high in Fe and Zn, is also a choice for being low in anti-nutritional compounds, namely, phytic acid. The presented study sought to identify the phytic acid content in several biofortified rice lines and determine the correlation of phytic acid with Fe and Zn content and yield characters. The research ran during the dry season (DS) from January to September 2022, with an alluvial soil type at the Sukamandi Experimental Station of ICRIST – Subang, West Java, Indonesia (altitude of 40 masl). Testing of 10 rice (Oryza sativa L.) genotypes comprising six BC4F3 biofortified rice lines for high Zn and four check cultivars (Inpari IR Nutri Zinc, Inpari 23, Ciherang, and Sintanur) used a randomized complete block design with three replications. Correlation analysis determined breeding strategies for high Zn/Fe rice with low phytic acid. The results revealed that phytic acid did not significantly correlate with Zn content, 1000-grain weight, and yield per plant. However, phytic acid had a strong positive correlation with Fe content. The rice line WR10 occurred as the best line because it had the highest Zn content (33.80 mg kg-1) and lower phytic acid and Zn ratio (PA: Zn) compared with all check cultivars, giving the highest yield potential and better yield than the Ciherang cultivar.

The marigold and zinnia are prominent in the horticulture industry and are widely growing flowering annuals in Pakistan. The well-timed study sought to investigate the effect of different fertilizer combinations on flowering annuals marigold and zinnia. The experiment comprised a completely randomized design with four replications during 2019 and 2020 at the Plant Genetic Resource Institute, National Agricultural Research Center, Islamabad, Pakistan. The data included recording days to bud formation (DBF), days to flower persistence (DFP), flowers per plant (NFP), and days to flower senescence (DFS). Significant differences were recordable among the genotypes and treatments. Average DBF under applications of NPK fertilizers and Grow More + HB101 + Vitafeed (foliar application) revealed higher during the first year of study compared with the second year. The most effective foliar application treatment for DBF of marigold and zinnia resulted in 0.18 g Grow More + 0.18 g HB101 + 0.18 g Vitafeed. A higher number of DBF marigolds occurred for treatment 20% N + 16% P + 14% K, and the same emerged for NFP. Average days for flower persistence in marigold and zinnia were higher under manures application compared with NPK and foliar application. The higher number of DFP of both plants existed for treatment 75% leaf compost (LC) + 25% soil. The organic and inorganic fertilizers may help develop plant health, resistance to early flower senescence, and large flower size of both marigold and zinnia.
万寿菊和百日菊在园艺工业中占有突出地位，在巴基斯坦广泛种植一年生开花植物。这项适时的研究旨在调查不同肥料组合对开花一年生植物万寿菊和百日菊的影响。该实验由完全随机设计组成，于2019年和2020年在巴基斯坦伊斯兰堡国家农业研究中心植物遗传资源研究所进行了四次重复。数据包括记录芽形成天数(DBF)、花持续天数(DFP)、单株花数(NFP)和花衰老天数(DFS)。基因型和处理之间存在显著差异。施用氮磷钾和叶面施用Grow More + HB101 + Vitafeed的平均DBF在研究第一年高于第二年。金盏花和百日菊的叶面施药效果为0.18 g Grow More + 0.18 g HB101 + 0.18 g Vitafeed。在20% N + 16% P + 14% K处理下，DBF金盏花的数量较高，而在NFP处理下，DBF金盏花的数量也较高。与氮磷钾和叶面施用相比，施用肥料的万寿菊和百日菊花的平均持续时间更长。75%的叶片堆肥+ 25%的土壤处理，两种植物的DFP均较高。有机和无机肥料可以促进植物健康，抵抗早花衰老，以及万寿菊和百日菊的大花大小。

Strawberry (Fragaria x ananassa Duchesne ex Rozier) is an economically important fruit crop grown commercially worldwide due to its known nutritional value. The demand for strawberries in the Philippines has been increasing but varietal development is slow due to the lack of genetic information on locally available germplasm. In addition, molecular marker resources for strawberries are limited. Here, we developed Simple Sequence Repeats (SSR) markers to characterize strawberries cultivated in tropical environments, particularly in the Philippines. In silico mining generated a total of 219,239 SSR markers, from which 160,025 unique markers were identified. Polymorphism scoring and the variation on the expected alleles resulting to the synthesis of the top 160 markers were validated using representative strawberry cultivars from the core collection. All 70 markers produced successful amplicons from all the genotypes, but only 67 markers displayed polymorphism. Using UPGMA, genetic similarities among the cultivars were calculated generating a dendrogram which categorized the strawberry cultivars into 3 groups. The grouping clearly showed the separation of the diploid Fragaria vesca from the octoploid F. x ananassa cultivars, considered as group 1. Furthermore, Groups 2 and 3 contained cultivars from different geographical origins (US, Japan, and North America). The eight novel markers developed and validated here can be added to the genetic marker resource for cultivar verification, assessment of genetic diversity, and most importantly, marker-assisted breeding.
草莓(Fragaria x ananassa Duchesne ex Rozier)是一种经济上重要的水果作物，由于其已知的营养价值而在全球范围内被商业化种植。菲律宾对草莓的需求一直在增加，但由于缺乏当地可用种质的遗传信息，品种发育缓慢。此外，草莓分子标记资源有限。在这里，我们开发了简单序列重复(SSR)标记来表征在热带环境中栽培的草莓，特别是在菲律宾。在硅矿中共产生219,239个SSR标记，从中鉴定出160,025个独特标记。利用核心种质的代表性草莓品种，对前160个标记的多态性评分和预期等位基因变异进行了验证。所有70个标记均产生了所有基因型的成功扩增子，但只有67个标记显示多态性。利用UPGMA算法计算了各品种间的遗传相似性，得到了草莓品种的树图，并将草莓品种划分为3个类群。分组清楚地表明，二倍体的花枝花从八倍体的凤梨品种中分离出来，认为是第1组。此外，类群2和类群3包含不同地理来源的品种(美国、日本和北美)。本文开发和验证的8个新标记可用于品种鉴定、遗传多样性评估，最重要的是用于标记辅助育种。

Hybrids with heterotic effects manifest themselves with a significant enhancement in growth and productivity traits compared with their parental genotypes. However, inbreeding resulted in decreased heterosis. Researchers believe that a noteworthy increase in F1 hybrids for economic and biological attributes is evident due to heterozygosity and overdominance of the corresponding genes of different parents combined in one genotype. The presented study sought to determine the heterotic effects of sugar beet hybrids for economically valuable traits and select the best parental lines with crossing potential for productivity. Five different sugar beet hybrids, analyzed during the crop seasons 2021 and 2022 for accurate and hypothetical heterosis and the degree of dominance in F1 generation for economically valuable traits like productivity and sugar content, transpired at the LLP – Kazakh Research Institute of Agriculture and Plant Growing (KazRIAPG), Kazakhstan. The crossing of the sugar beet line KazMS with pollinators, viz., VP24, VP44, OP17231, OP17232, and OP14044, changed the type of inheritance in hybrids for productivity from negative dominance in variants with pollinators (VP24, OP17231) to overdominance in variants with pollinators (VP44, OP14044). Based on the results, the conclusion indicated that the type of productivity inheritance in F1 hybrids involving the same maternal line differed.

The presented research investigated the pollen morphology of endemic Iraqi Hypericum species. The study revealed phenotypic features of pollen grains in the polar and equatorial views and their quantitative and qualitative characteristics. The results showed that the pollen grains of the genus Hypericum were radially symmetrical and isopolar, and their apertures were simple and tricolporate, except the species H. davisii, distinguished as tetracolprate. Dividing the studied species based on pollen grain sizes comprised two groups. Small pollen grains with an average length of the equatorial view ranged between 10–16 μm in H. lysimachioides and H. vermiculare. Medium-sized pollen grains with an average extent between 17–26 μm emerged in the species, i.e., H. retusum, H. triquetrifolium, H. perforatum, H. lydium, H. tetrapterum, H. asperulium, H. scabrum, and H. davisii. Pollen grains, also divided according to the P/E ratio, had two main groups. The pollen grains were subprolate and spherical, with the exine sculpturing examined by a scanning electron microscope (SEM), and isolated into four groups: 1) microreticulate reticulum, including H. asperulium, H. lydium, and H. vermiculare, 2) perforate, i.e., H. retusum, H. scabrum, H. tetrapterum, and H. triquetrifolium, 3) psilate with H. perforatum and H. davisii, 4) and reticulate exine sculpturing in H. lysimachioides, all isolated from the rest of the species. SEM images showed the thickness of exine ranged from 0.5 to 2 μm. The topical study also added H. davisii as a new species with no previous records in Iraq. This pollen study added valuable data for taxonomy and suggested that it should proceed with its first-time registration in Iraq. The pertinent research could provide a taxonomical key for Hypericum species in Iraq.

The promising research showcased the results of herbicides’ uses, considering the quantitative composition of weeds with zero tillage technology of winter wheat cultivation. It revealed that when treating wheat seeds with the growth stimulator Vimpel (0.5 l/t) and micro-fertilization with Oracle (1.0 l/t) simultaneously etching with the fungicide Bunker (0.4 l/t), as well as, early spring treatment of crops in the tillering phase of winter wheat with the same stimulator (Vimpel, 0.5 l/ha) and micro-fertilization (Oracle multicomplex, 2.0 l/ha) simultaneous with the herbicide “Ballerina” (0.5 l/ha) application, the number of preserved plants before harvesting was 286.1 pcs./m2, reaching a height of 88.9 cm, with a productive bushiness of 1.15 pcs., grains per spike (22.2), 1000-grain weight (34.8 g), and collected dry grains at a standard humidity (22.1 c/ha). It was also evident that the competitive productivity of winter wheat also emerged when treating wheat seeds with biological fertilizer Biobars–M (1.0 l/t), the crop at the tillering stage with Biobars–M (0.5 l/ha), and the earring phase (0.7 l/ha). Similarly, using growth stimulants Vimpel and micronutrient Oracle multicomplex enhanced the grain yield with reduced cost of production (USD 61.3–66.0/kg) compared with the control version (USD 78.6 /kg). On one hectare of winter wheat crop, the net income ranged from USD 289.55 to 443.56.

Conventional breeding is vital in improving yield-related traits and developing high-yielding cultivars. In the presented study, an evaluation of 15 F1 hybrids compared them to their six parental genotypes for genetic variation of various traits. The results showed that the analysis of variance revealed significant (P ≤ 0.01) differences among the cross combinations and parental cultivars and among the parents and crosses. The mean sum of squares of parents vs. crosses also indicated substantial (P ≤ 0.01) for all the characteristics. The general (GCA) and specific combining ability (SCA) variances were significant (P ≤ 0.01) for all traits studied in the F1 generation. Three varieties, namely, Sakha108, Giza179, and Sakha109, were highly significantly positive for grain yield plant-1, which means these varieties can benefit as good combiners to transfer the said trait in the breeding program. In SCA, seven crosses were negative in plant height and a negative value was desirable to avoid lodging and suitable for mechanical harvesting; however, positive significant values are preferable in the rest of the traits. The results indicated that the best crosses for grain yield plant-1 and plant height were Sakha105 × Sakha102, Sakha105 × Sakha108, and Sakha108 × Sakha109. Conducting cluster analysis also exhibited the genotypes dividing into four groups. The first group included rice genotypes Sakha109 and Sakha108 alone. These cultivars, produced from a common parent Sakha101, could have genetic relations for three quantitative traits (flag leaf area, 1000-grain weight, and panicle weight). The second group, comprising Sakha 102 and Sakha 106, has a very similar genetic background because both cultivars share a common parent, Giza 177. In addition, these two rice cultivars had at par number of tillers plant-1, 1000-grain weight, and panicles plant-1. The third group included only Giza 179 belonging to Indica-Japonica varieties. A fourth group has Sakha 105 produced by different parents.

As wheat donors, wild species of the genus Aegilops L. play a vital role in practical breeding to improve wheat production because of their strong relationship and wide genetic diversity. Using nine simple sequence repeat (SSR) markers helped assess the genetic diversity in 96 collected samples of four species belonging to the genus Aegilops, i.e., Aegilops tauschii Coss (D), Ae. cylindrica Host (CD), Ae. crassa Boiss (DDM), and Ae. triuncialis L. (UC). The said collection came from 21 sites of various expeditions located in three regions of Southwestern Uzbekistan (Samarkand, Urgut, Kitab, and Shakhrisabz regions). Generally, 102 distinct alleles were found, with an average of 11.33 alleles per primer. The total number of species-specific amplicons was 35. The polymorphism detected varied from 28.6% (for the WSP107 primer) to 77.0% (for the WSP130 and WSP192 primers). The mean values of polymorphism information content (PIC) and expected heterozygosity (Ho) for all samples were 0.675 and 0.527, respectively. Based on nine SSR markers, on average, the genetic distance indices (GD) varied from 0.63 to 0.77. The highest genetic similarity (GD = 0.77) recorded occurred between the species Ae. crassa and Ae. cylindrica, whereas the least (GD = 0.48), between Ae. cylindrica and Ae. triuncialis with their taxonomic classification. Genus Aegilops samples from the same region often attain an identical subgrouping, which might be due to relatedness by genetic parameters. The gene pool of native species of the genus Aegilops from the Southwestern region of Uzbekistan may provide suitable alleles for wheat improvement and adaptation in the future.
