Abstract Present study is performed to evaluate the effects of foliar application of salicylic acid, glycine betaine, ascorbic acid, nano-silica and nano titanium dioxide on yield and yield component of sunflower. Chlorophyll content, leaf length, leaf width, days to 50 % flowering, day to maturity, plant height, husk percentage, number of seeds per head, head number per plant, percentage of empty achenes, 1000-seed weight, kernel weight, grain length, straw yield, harvest index, grain yield and oil percent were measured. Results showed that the first two principal components accounted 49 % and 19 %, respectively of sums of squares of the TT interaction and were used to create a two-dimensional treatment by trait (TT) biplot. The vertex treatments in polygon of TT biplot were ascorbic acid, glycine betaine, nano-TiO2 and control which Nano-Ti2 treatment indicated high performance in chlorophyll content, day to maturity, number of seeds per head, head number per plant, kernel weight, grain length, straw yield, harvest index, grain yield and oil percent. The identification of ideal treatment, the treatment that is most favorable treatment among all treatments, showed that the nano-TiO2 might be used in selecting superior traits and it can be considered as the candidate treatment. Treatments suitable for obtaining of high seed yield were identified in the vector-view function of TT biplot and displayed nano-silica and nano titanium dioxide as the best treatments suitable for obtaining of high seed yield. In short, nano-fertilizer could increase crop yields and improve the fertilizer efficiency.

Abstract The samples of Plasmopara halstedii (the causal agent of sunflower downy mildew) were collected on sunflower fields in south of the Russian Federation: in the Krasnodar, Rostov and Stavropol regions, and in the Republic of Adygea in 2016 and 2017. Virulence code of 545 isolates was identified; i. e. 280 isolates originating from 24 fields in 2016, and 265 isolates from 17 fields in 2017. Races 330, 334, 710 and 730, widespread within the region in previous years, were found in all mentioned areas. In addition, races 713, 733 and 734 have been detected in several districts of the Krasnodar region since 2016. This is the first report of these races in Russia and above that the first record throughout Europe and Asia for the races 733 and 734. The identification of new P. halstedii races was confirmed by the method of cross inoculations from individual differential lines. The phenotype corresponding to virulence code 734 was in some cases disclosed as a mixture of race 334 with 710 or 730. The presence of several P. halstedii races on an individual plant was also confirmed for the first time in the territory of the Russian Federation.

Abstract Sixteen sunflower hybrids obtained by crossing between four CMS and four restorer lines as tester were evaluated for combining abilities of agronomic traits under optimum and water limited conditions using line×tester mating design. There was considerable variability among genotypes for the traits in both normal and stressed experiments. The results indicated that the lines AGK344 and AGK148 with suitable GCA for early maturity and plant height respectively and AGK52 for oil content and seed and oil yield were desirable combiner under both optimum and stressed condition. In other hand, AGK344 expressed a significant GCA for plant height in suitable direction under stressed condition. Among the testers RGK26 and RGK56 had suitable GCA for days to maturity under both conditions. RGK56 and RGK26 were appropriate combiner for oil content under optimum and water stressed conditions respectively the later had desired GCA for seed and oil yield under water stressed condition too. According to the results, there was differentiate GCA of testers for days to flowering, seed weight and oil content in normal and stressed condition. Differential expressions of GCA in parent inbred lines indicated that selection of restorer lines for the agronomic traits would be more efficient than the selection of CMS lines. It is concluded that heritability of a trait determines the kind of SCA in response to different environments and the SCA effects are more stable for traits with higher heritability.

Abstract Genetic makeup along with environmental stimuli affect the expression of a trait in plants. Drought tolerance in addition to stability of characters over a wide range of environmental conditions is not well studied in sunflower. Therefore, here we have performed a stability analysis study of sunflower genotypes. The experimental material comprised of 19 lines of sunflower comprising 9 alloplasmic cms lines from different wild sources along with one common maintainer from petiolaris source, 4 cms lines and one maintainer from cultivated source (cytoplasm from H. petiolaris), 4 restorer lines and 60 F1 hybrids (developed in line x tester design). The experiment was conducted over two years i. e. spring season 2011 and spring season 2012 over the two environments one normal irrigated and another water stress environment at Punjab Agricultural University, Ludhiana, India. The data were recorded for different morphophysiology, yield and quality trais and analysis as per standard procedures. The genotype×environment interaction was further partitioned into linear and non-linear components according to Eberhart and Russel model. Eleven sunflower hybrids were found to be stable across the environments for seed yield. While, sufficient variability was also recorded for the oil content with the highest oil percentage in the cross combination ARG-2A×P100R (34.61). Overall, this study provides useful information regarding the stability of newly developed and cytoplasmically diverse sunflower hybrids under north Indian conditions.

Abstract Sunflower is an important source for edible oils and biodiesel production. Its productivity is limited by many agronomical practices one of which is the sowing date. In this study, the effects of different sowing dates from early April to late June on phenology and yield of sunflower cultivars were investigated. The results showed that sunflower has a relatively long period of possible sowing dates, stretching from early April to late June in North West of Iran. However, delayed sowing dates significantly decreased the number of days needed for phenophases. For every day of delay, the model predicted (R2=0.97) a losing rate in achene yield by 22.2 kg h−1 from the first sowing date. For relationships between growing degree days (GDD) and yield, almost the same results were obtained. About 22 kg h−1 reduction (R2=0.79) in yield per day was estimated by GDD index when the average GDDs per day was 14.2. However, helio-thermal units (HTU) did not predict this reduction accurately. A suggested comprehensive model, that used the percent of yield losses and changes in vegetative to reproductive ratio, found a significant and positive relationship between the indices and yield losses. For all indices, an increase in vegetative to reproductive ratio resulted in increased grain yield losses.
向日葵是食用油和生物柴油生产的重要来源。它的生产力受到许多农业经济学实践的限制，其中之一是播种日期。研究了4月初至6月下旬不同播种期对向日葵品种的根系和产量的影响。结果表明，在伊朗西北部，向日葵的可能播种期相对较长，从4月初一直持续到6月下旬。然而，推迟播种日期显著减少了表型所需的天数。对于每延迟一天，该模型预测（R2=0.97）瘦果产量的损失率为22.2 kg h−1。对于生长度天数（GDD）和产量之间的关系，获得了几乎相同的结果。约22 当每天的平均GDD为14.2时，通过GDD指数估计每天产量减少kg h−1（R2=0.79）。然而，日热机组（HTU）并没有准确预测这种减少。一个建议的综合模型使用了产量损失的百分比和营养与生殖比例的变化，发现这些指数与产量损失之间存在显著的正相关关系。就所有指标而言，营养与生殖比例的增加导致粮食产量损失增加。

Abstract In the Russian Federation the most favorable area for high and stable yields of sunflower crop is the Northern zone of Krasnodar region. The research was conducted in multivariate experience of long-term stationary monitoring. We researched the effect of doses of mineral fertilizers and furolan on sunflower yield and seed quality. It was found that it is expedient and cost-effective to use small doses of nitrogen fertilizers for sunflower. The expediency of application of plant growth regulator (Furolan) during vegetation is shown. We found that the use of mineral fertilizers and the use of furolan contributed to the activation of growth processes of sunflower plants which led to the formation of optimal plant density. Improving the nutritional status of plants has provided an increase in the leaf area unit. The treatment of sunflower crops on the background of fertilizers N20P30 and the furolan has had a positive impact on the value of photosynthetic potential. Under the influence of mineral fertilizers there was an increase in the dissemination of the sunflower head, weight of seeds and weight of 1000 seeds, which has a positive impact on productivity. With the increase of fertilizer doses, the oil content of seeds increased when compared to the unfertilized variant. The treatment of plants with furolan has not violated the process of accumulation of protein and fat.

Abstract Developing hybrids, resistant to causal pathogen of Downy mildew (Plasmopara halstedii (Farl.) Berl. & de Toni), is one of the critical tasks in sunflower breeding. Molecular markers have advanced breeding practice in the past decades, however there are still unmet needs for reliable high-throughput (HT) selection of the pathogen resistant starting material and differentiation of the plants infected by different pathogens. In this study, we tested the known DNA marker (308 bp fragment from ribosomal DNA of P. halstedii) for detection of pathogen in different tissues of sunflower plant and at different stages of plant development. Specified DNA marker was re-validated in the total DNA, isolated from sporangium as well as from seedlings of infected pathogen resistant/susceptible inbred lines of Ukrainian breeding and 60 F2 crosses. An independent set of field grown plants with unknown resistance to P. halstedii, having symptoms of the bacterial/fungal/viral pathology were used for HT screening and genotypes, infected with downy mildew, were successfully identified. Pathogen appeared to be concentrated in the vessels of sunflower leaves, in contrast to parenchymal tissue. Our study demonstrates an addition to whole seedling inoculation technique of P. halstedii detection, which allows HT identification of the pathogen infected and non-infected sunflower plants.

Abstract The present research aimed to study gene effects for oil content and fatty acid composition in sunflower. It involved a set of 92 hybrids developed by crossing four CMS lines with 23 perfect restorers. Experiment was conducted at experimental field area of Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana, Punjab, India. The data was recorded on oil content and quality traits. The analysis of variance revealed significant differences among the traits studied. Among the lines; CMS 42A was observed to have higher significant positive gca effects for oil content, linoleic acid & linolenic acid and higher significant negative gca effects for palmitic acid and stearic acid, whereas, for oleic acid line, CMS 40A had higher positive gca effects. Among the testers, TSG 275 had higher significant positive gca effects for linolenic acid and significant negative gca effects for stearic acid. High positive gca effects for oleic acid and oil content were observed for TSG 331. The tester OPH 91 was good combiner with high positive gca effects for oleic acid and negative gca effects for palmitic acid, whereas, tester TSG 288 exhibited highest positive gca effects for linoleic acid. The best cross combinations; CMS 40A×TSG 259, CMS 607A×TSG 271 and CMS 40A×OPH 73 showed significant specific combining ability effects for oil content and cross CMS 40A×TSG 289 had significant specific combining ability for oleic acid and linoleic acid. The cross combination CMS 40A×TSG 259 is giving a significant jump of over 12 % against the current commercial check for oil percentage and for other quality traits more than 50 % over the standard check, which is significant for undertaking improvement of hybrid for oil quality.

The cross combination CMS 40A×TSG 259 is giving a significant jump of over 12 % against the current commercial check for oil percentage and for other quality traits more than 50 % over the standard check, which is significant for undertaking improvement of hybrid for oil quality.","PeriodicalId":39086,"journal":{"name":"Helia","volume":"42 1","pages":"73 - 84"},"PeriodicalIF":0.0,"publicationDate":"2018-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/HELIA-2018-0006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47145850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Abstract Wild Helianthus species should have be a main interest sunflower breeding for the introgressing elite genes for biotic and abiotic stress. The future use of wild sunflower in development of drought resistance cytoplasmic sources should be expanded to the wide range of wild species as compared to conventional sources. The objective of this study was to evaluate different parental lines for their water-use efficiency and seed yield performance under two environments for two years. ARG-2A received from H. argophyllus, 234A and 38A from H. petiolaris were found to be the most susceptible genotypes, whereas, 42A, 42B from H. petiolaris and ARG-6A (H. argophyllus) were found to be tolerant to drought stress. CMS-XA, RCR-8297, E002-91A, NC-41B and P124R were observed to be well adapted to stress environments. ARG-3A from H. argophyllus had a stable performance over the environments, which may be useful to develop water use efficient hybrids having diversified cytoplasmic backgrounds in sunflower breeding.
