Thirty-four tomato genotypes from different geographical locations were evaluated for genetic diversity and screened for bacterial wilt (BW) caused by Ralstonia solanacearum. Results revealed that plant height, fruits per cluster, fruit weight, fruit diameters, locules per fruit, fruit firmness, yield per plant, and quality parameters exhibited high heritability and genetic advance. Clustering based on D2 analysis, classified genotypes into four clusters. Maximum intra-cluster distance was recorded within cluster I and maximum inter-cluster distance between cluster II and IV followed by cluster I and IV, indicating existence of wide genetic variability. Genotypes in cluster IV (AVTO 1711, AVTO 1717 and AVTO 1718) recorded high fruit weight coupled with high yield. These may be explored as promising donors for developing large sized bacterial wilt resistant tomatoes. The large fruited genotypes in cluster IV can also contribute to the genetic improvement of existing bacterial wilt resistant varieties placed in cluster I. Out of 34 genotypes screened for BW disease, 5 genotypes were classified as resistant and 7 as moderately resistant.

Eight varieties of fennel (Foeniculum vulgare Mill.) were evaluated under field trial for their stability of yield, yield attributes and essential oil content under the organic production system in six consecutive years from 2016 to 2021. Mean square due to environment + (variety × environment) was significant for all the traits studied indicating the existence of variety × environment interaction. Based on the mean performance, regression coefficient and deviation from regression values, it was found that stability of yield and yield components are imparted in the varieties, GF-12 and AF-1 across the years through the stable performance of characters and like numbers of primary and secondary branches, number of umbels and umbellate and seed yield. However, variety RF-101 for essential oil content can be considered as most suitable, stable and adopted to organic production system compared to other varieties. Correlation analysis revealed highly positive relationship in plant height, number of primary branches, number of umbels and umbellate per plant and seed yield. Based on the findings, fennel growers are apprised to select stable high-yielding fennel varieties for the organic production systems in semi-arid regions of India. Along with their use in hybridization programmes to converge the stability characteristics of seed yield for the development of a stable variety adapted to a wider range of environments under organic production systems.

Climate change poses significant challenges to root and tuber crops, requiring robust adaptation strategies to mitigate vulnerabilities. This review examines the impacts of climate change on root and tuber crops, including rising temperatures, altered rainfall patterns, extreme weather events, and changes in pest and disease dynamics. These changes significantly affect root and tuber crop production, leading to lower yields, compromised quality, increased susceptibility to pests and diseases, and limited access to water resources. Adaptation strategies encompass various approaches, such as agronomic practices, crop diversification, improved water management, breeding for climate resilience, and agroecological methods. However, addressing knowledge gaps and research needs is crucial for better-understanding climate change impacts and developing effective adaptation strategies for root and tuber crops. Future research should prioritize resilient cultivar identification, enhanced cropping systems, improved pest and disease management, and exploring socio-economic dimensions of adaptation. This review emphasizes the urgent need to address climate change impacts on tropical root and tuber crops. It highlights the critical role of adaptive measures in ensuring long-term sustainability and food security in a changing climate

Ber is an indigenous and common fruit of India. It is commercially grown under wide climatic and soil conditions. Apple ber (Zizyphus jujube Mill) cultivar is gaining momentum in sub-tropical and tropical climatic conditions of West Bengal, Telangana, Andhra Pradesh, Maharashtra, Rajasthan, Gujarat and in several northern parts of India. It is precocious in bearing habit with bold and crispy fruits. Many factors including training practices affect vegetative and fruit quality parameters. Due to bolder and heavier fruits, the cultivar is prone for limbs breakage or complete tilting of plants which results in uneven fruiting, reduced fruit set, and higher fruit drop. Considering its appealing fruit taste and quality and to address the above mentioned issues, different training systems were evaluated to see its performance on three to four years old apple ber orchards. Plants were trained on different training systems viz. Y-Shape, Espalier training system and control. Observations were recorded on vegetative and fruit quality parameters. Training systems significantly influenced various vegetative, yield and fruit quality parameters. Vegetative parameters such as leaf area, physical and quality attributes viz., fruit weight and size, TSS, ascorbic acid, yield, and B: C ratio were better in Y-Shape training system. Hence, Y- Shape training system can be adopted to improve yield and fruit quality parameters in Apple ber.
它是印度本土常见的水果。它在广泛的气候和土壤条件下被商业化种植。在西孟加拉邦、特伦甘纳邦、安得拉邦、马哈拉施特拉邦、拉贾斯坦邦、古吉拉特邦和印度北部几个地区的亚热带和热带气候条件下，Apple ber (Zizyphus枣Mill)品种正在获得发展势头。早熟，果实粗壮脆脆。包括训练在内的许多因素都会影响营养和果实品质参数。由于果实粗壮厚重，植株容易断肢或完全倾斜，结果不均匀，坐果减少，落果率高。考虑到其诱人的水果味道和质量，并针对上述问题，对不同的培训系统进行了评估，以观察其在三到四年龄苹果园中的表现。植物在不同的训练系统上进行训练，即Y-Shape、Espalier训练系统和控制。记录了营养和果实品质参数的观察结果。训练系统显著影响各种营养、产量和果实品质参数。在y型培养体系中，叶面积、果实重量和大小、TSS、抗坏血酸、产量和B: C比等营养参数表现较好。因此，可以采用Y型训练系统来提高苹果产量和果实品质参数。

Mango fruits majorly suffers from anthracnose and fruit fly infestations during storage, transportation and marketing. Hot water treatments (HWTs) at specific levels have shown to control the incidence of these important threats. Application of HWT not only act as a quarantine measure, but also maintains the quality and enhance the marketability of fruits, even at room temperature (RT), leading to its vast applicability in local / international markets. In this study, post harvest application of HWTs (48°C for 60 min and 55°C for 10 min) in mango cv. Banganapalli recorded reduced ethylene production rate, physiological loss in weight, improved sugar content, ascorbic acid, total carotenoids, phenolics and antioxidants compared to control. Combination of HWTs (48°C for 60 min followed by 55°C for 10 min) resulted in degradation of some quality parameters compared to individual HWT and control.

The genetic diversity and population relationship was determined in 14 genotypes of parthenocarpic cucumber (Cucumis sativus L.) using simple sequence repeats (SSR) markers. In this study, fifty-nine SSR markers comprehensively showed polymorphism among cucumber genotypes. Total 252 alleles were identified with an average of 4.27 alleles per locus, while the polymorphism information content (PIC) of the primers ranged from 0.34 to 0.84 with a mean value of 0.62. The major allele frequency and heterozygosity ranged from 0.21 to 0.75 and from 0.43 to 0.89, respectively. Maximum major allele frequency was reported with primer Cs- Female-4, whereas the maximum value of polymorphic information content was found with the primer SSR11742. The dendrogram clustered genotypes into two main groups A and B with 8 and 6 genotypes, respectively. Jaccard’s similarity coefficient ranged from 0.63 to 0.86 with maximum similarity between genotypes DDPCG3 and PLP-1, whereas minimum similarity was observed between DDPCG8 and PLP Gy-1-08B. The population structure revealed three sub-populations with some admixtures. Principal coordinate analysis (PCoA) with SSR markers revealed that the genotypes were uniformly distributed across the two axes in both the plots with 41.76% of cumulative variation. The genetic divergence within indigenous genotypes allow genotypic identification, gene mapping and cloning for improvement in cucumber breeding.

Mango genotypes that are salinity tolerant can possibly be used as clonal rootstock for sustained production of salinity sensitive commercial mango cultivars in salt affected soils. Present study was carried out to elucidate the effect of salinity stress induced by salts of NaCl+CaCl2 (1:1) at concentrations of 0, 25, 50 and 100 mM on fifteen polyembryonic mango genotypes. The physio-biochemical parameters such as relative water content, chlorophyll content, epicuticular wax content, water potential (Ψ), carbohydrate content, lipid peroxidation, proline accumulation and antioxidant enzymes were determined at each level of salinity in all genotypes. On the basis of these physio-biochemical changes, the study illustrated that the polyembryonic genotypes, Turpentine, Deorakhio, Olour, Bappakkai, Vattam, Nekkare, Kurukkan, Kensington, Muvandan, EC-95862, Manipur, Sabre, Vellaikolamban, Kitchener and Mylepelian were in the decreasing order in response to salinity stress tolerance.

Cashew (Anacardium occidentale L.) is an important tropical nut crop of social and economic importance worldwide. However, the crop is threatened with the low yield. In the present study, an attempt was made to test the effects of plant growth hormones as well as micronutrients on nut and apple quality of cashew var. Bhaskara. Significant differences in kernel weight, shelling percentage, carbohydrates and starch content of cashew kernel and juice content of cashew apple were observed with the foliar application of growth hormones and micronutrients. The foliar application of ethrel @ 50 ppm increased shelling percentage (35.8%), carbohydrate content (21.63%), sugar content (6.26%), protein content (32.4%), starch content (31.42%), juice content (78.3%) and total soluble solids (120 Brix). Further, the foliar spray of zinc sulphate (0.5%) + borax (0.1%) increased shelling (36.13%), protein content (32.15%), starch content (32.03%) among all the treatments tested. Furthermore, higher cashew apple juice content (78%) and total soluble solids (120Brix) was also recorded with the foliar spray of zinc sulphate (0.5%) + borax (0.1%).

Investigations were carried out to identify the source of resistance in 67 bottle gourd genotypes for gummy stem blight, powdery mildew and cucumber green mottle mosaic virus (CGMMV) diseases, under natural field epiphytotic conditions. The genotypes BG-95 (105.13), BG-114-1 (131.04), BG-114-3 (208.81) and BG-77-6-1 (221.80) were resistant for gummy stem blight with low AUDPC values, while, BG-125-5 (232.22), BG-6-3 found (250.00), BG-125-4 (307.78), BG-8-1 (308.89), BG-125-2 (311.11) and BG-124-2 (423.33) resistant with low AUDPC values for powdery mildew. Further, the two genotypes such as IIHR-19 and BG- 131 showed field level resistance against CGMMV. The selected genotypes based on field evaluation were subjected for artificial screening under glass house conditions. The genotypes, recorded consistent resistant reactions were BG-114-3, BG-77-6-1 and BG-95 for gummy stem blight disease and BG-6-3, BG-8-1, BG-125-4 and BG-125-2 for powdery mildew. The stable and durable source of resistance identified for gummy stem blight and powdery mildew in bottle gourd genotypes will hasten the process of developing resistance varieties in bottle gourd.
