Five different rapeseed genotypes were tested. The following traits were considered: seed yield, seed germination, seed oil content, 1000 seed weight and seed protein content and they were used to determine whether there is significant or nonsignificant correlation. Highest average results were determined in genotype G-3 (yield 2.544 kg; germination 90%; 1000 seed weight 4,30 g; oil content 45,31% and protein content 19,83%) while G-5 (1.838 kg; 87%; 3,50 g; 44,77% and 17,28%) had the lowest average result of observed parameters. Highly significant positive correlations were found while comparing seed yield with 1000 seed weight (0.753**) and protein content (0.726**). High significant positive correlation were also determined comparing seed germination with 1000 seed weight (0.832**) and protein content (0.892**). Also high significant correlation was determined comparing 1000 seed weight and protein content (0.812**). Positive significant correlations were found by comparing seed yield and seed germination (0.644*). Path analysis indicated highest significant positive direct effect of 1000 seed weight (0.716**) and protein content (0.666**) on seed yield. High but negative significant value had seed germination (-0.645**). In the study of indirect effects on seed yield, none of significant effects were determined. The study of direct effects on oil content showed that the seed germination had high significant positive effect (-1.296**) on oil content. Significant but hot high effect has seed yield (0.556*). In other two traits it was determined negative high significant effects (1000 seed weight - 0.797** and protein content - 0.717**) on seed oil content. The existence of indirect significant effects on oil content in four cases was determined.

AbstractThis study was carried out to determine the correlation between agronomic traits and seed yield of sunflower hybrids and also to determine the direct and indirect effects of analyzed traits on seed yield. The primary task in sunflower breeding programs is to increase the seed yield, as well as create new hybrids with high potential for seed and oil yield. The experiment was set up according to randomized block design during two growing seasons (2013 and 2014), on research area of the Faculty of Agriculture, “Goce Delchev” University – Shtip, in Ovche Pole locality, Republic of Macedonia. As an experimental material 20 sunflower hybrids were used. 1,000 seed weight, seed length and width, oil content, oleic acid content and seed yield were analyzed. 1,000 seed weight showed positive and significant correlation with seed width, seed length and seed yield. On the other hand, negative and significant correlation was obtained between 1,000 seed weight and oil content. 1,000 seed weight expressed the highest positive direct effect on seed yield. The results obtained from correlation and path analysis showed that the efficiency in the selection of seed yield in sunflower hybrids should increased through the selection of 1,000 seed weight.

The most important criteria for introducing new confectionary hybrids into the production is high protein yield. Path coefficient analysis was used to obtain information on direct and indirect effects of studied traits (seed oil content, kernel oil content, seed yield, kernel protein content, mass of 1000 seeds, kernel ratio and hull ratio) on protein yield. The research was conducted during three vegetation seasons, on 22 experimental confectionary sunflower hybrids created in the breeding program at the Institute of Field and Vegetable Crops. Strong and very strong correlations were found among the largest number of examined traits. A weak negative interdependence was determined between kernel oil content, kernel protein content, mass of 1000 seeds, hull ratio, and protein yield using the analysis of simple correlation coefficients. Positive but weak correlation was determined between protein yield and seed oil content, and kernel ratio. Very strong positive correlation was determined between protein yield and seed yield (0.468**). The seed oil content had a very strong direct negative effect on protein yield (DE=-0.734**). The mass of 1000 seeds had a weak negative direct effect on protein yield. Kernel protein content and kernel oil content demonstrated a weak direct positive effect on protein yield. Path coefficient analysis of protein yield showed a very strong positive direct effect of kernel ratio (DE=1.340**), seed yield (DE=0.657**) and hull ratio (DE=0.992*). These findings confirm the effect of seed yield, kernel ratio, and hull ratio on protein yield, and their importance as the selection criteria in confectionary sunflower breeding.

Path coefficient analysis was applied to gain information on direct and indirect effects of studied traits (seed oil content, kernel oil content, seed protein content, kernel protein content, head diameter, kernel ratio and plant height) on sunflower seed yield. Traits which exhibit the highest effects on seed yield will be used as a selection criterion in confectionary sunflower breeding. The research was conducted during three vegetation seasons on 22 experimental confectionary sunflower hybrids, created in breeding program the Institute of Field and Vegetable Crops. Among the largest number of examined traits, significant and highly significant correlations were found. With the analysis of simple correlation coefficients a low interdependence was determined between, kernel protein content, plant heights with seed yield. Negative but weak correlation was determined between kernel oil content, seed protein content, kernel ratio with seed yield. Established a negative strong correlation of head diameter (-0.190*) and negative very strong correlation of seed oil content (-0.351**) with seed yield. The seed oil content had a very strong direct negative effect on seed yield (DE=-0.831**). The head diameter, plant height, seed protein content had weak negative direct effect on seed yield. Kernel protein content and kernel oil content has demonstrated a weak direct positive effect on seed yield. Path coefficient analysis for seed yield showed very strong direct effect for kernel ratio (DE=0.487*) on seed yield, it shows that the kernel ratio is important selection criterion for confectionary sunflower breeding.

Aims: For proposing a statistical approach to select of the most promising genotypes for peanut breeding program. Place and Duration of Study: Twenty peanut genotypes were evaluated at Matana Agricultural Station Research, Luxor governorate, Egypt during 2018 and 2019. Study Design: In a randomized complete block design with three replications. Methodology: Analysis of variance (ANOVA), correlation coefficients, factor analysis, cluster method and some genetic parameters for seed yield and its components were calculated. Results: Results revealed that significant differences among the tested genotypes for the eight studied traits. Correlation coefficients indicated that seed yield was significantly correlated with all traits except plant height. Meanwhile, factor analysis was used to remove multi-collinearity problems, to simplify the complex relationships and to reduce variables number (into three extracted factors). 100-seed weight, number of branches/plant, 100-pod weight and seed oil content (%) with seed yield/plant traits which present in the 1st factor explained 42.039% of the total variance and recorded high heritability coupled with high genetic advance %. ANOVA results for factor scores obtained (native best multi-traits data) revealed that genotypes varied significantly. Conclusion: Factor and cluster analysis agreed in grouping Ismailia 2, Intr. 267, Intr. 182, Intr. 332 and Sohag 107 to be promising genotypes to increase peanut seed yield, whereas genotypes Intr. 504 and intr. 510 could be utilized to increase peanut seed oil content %. Then, the utilization of a factor score as a variable in ANOVA analysis was more appropriate rather than the original data. Consequently, factor scores (as a native data) would be more agreeable to selection and can be employed in plant breeding programs.

Flax cultures give dual-purpose production – flax fibre and seeds. Flax varieties adapted to local climate conditions have breeded but up to now the profound research of its quality was not carried out. In our investigation we analysed flax varieties of Latvia selection for seed yield and quality in comparison with standard varieties ‘Vega 2’ and ‘Lirina’. In Latgale Agricultural Scientific Centre 10 Latvian flax varieties are cultivated and seed yield, 1000-seed weight, seed oil content (extracted by hot pressing method) and fatty acid content in flax seed oil (detected with gas chromatography method) have evaluated. Seed yields of fibre flax Latvian varieties are significantly higher in comparison with standard variety ‘Vega’. All analysed seed samples have high oil content (27- 47%) and there is high percentage of polyunsaturated fatty acids in oil (linoleic acid 10,6-16,9%, linolenic acid 54,7-62,1%). There is little difference in 1000-seed weight, content of oil in seeds, percentage of linoleic, linolenic, oleic, palmitic and stearic acid in oil between fibre flax and oil seed flax varieties. The difference between the varieties is more influential. Flaxes seeds from Latvian varieties are in high quality and can be used for food, medical and technical purposes.

Abstract Background Cotton is not only a major textile fiber crop but also a vital oilseed, industrial, and forage crop. Oleosins are the structural proteins of oil bodies, influencing their size and the oil content in seeds. In addition, the degradation of oleosins is involved in the mobilization of lipid and oil bodies during seed germination. However, comprehensive identification and the systematic analysis of the Oleosin gene (OLEOs) family have not been conducted in cotton. Results An in-depth analysis has enabled us to identify 25 and 24 OLEOs in tetraploid cotton species G. hirsutum and G. barbadense, respectively, while 12 and 13 OLEOs were identified in diploid species G. arboreum and G. raimondii, respectively. The 74 OLEOs were further clustered into three lineages according to the phylogenetic tree. Synteny analysis revealed that most of the OLEOs were conserved and that WGD or segmental duplications might drive their expansion. The transmembrane helices in GhOLEO proteins were predicted, and three transmembrane models were summarized, in which two were newly proposed. A total of 24 candidate miRNAs targeting GhOLEOs were predicted. Three highly expressed oil-related OLEOs, GH_A07G0501 (SL), GH_D10G0941 (SH), and GH_D01G1686 (U), were cloned, and their subcellular localization and function were analyzed. Their overexpression in Arabidopsis increased seed oil content and decreased seed germination rates. Conclusion We identified OLEO gene family in four cotton species and performed comparative analyses of their relationships, conserved structure, synteny, and gene duplication. The subcellular localization and function of three highly expressed oil-related OLEOs were detected. These results lay the foundation for further functional characterization of OLEOs and improving seed oil content.

Twenty-eight genotypes of lettuce including check cultivars viz., Simpson Black Seeded and Great Lakes were grown in a RCBD with three replications during Rabi 2011-12 and 2012-13 at Vegetable Experimental Research Farm, Nauni, Solan H.P. to estimate the parameters of genetic variability, correlation and path analysis undernaturally ventilated polyhouse. Analysis of variance showed highly significant differences among genotypes for all the characters under study. Variability revealed that phenotypic co-efficient of variation (PCV) in general were higher than the corresponding genotypic co-efficient of variation (GCV) for all the characters. High co-efficient of variability were found for heading percentage (37.00% and 36.01%), incidence of sclerotinia rot (63.49% and 61.475%), gray mould (90.13% and 88.08%) and yield per plot (39.55% and 33.09%) indicated wider range of variation and offer better scope for improvement through selection. High heritability estimates coupled with moderate genetic gain were observed for yield and other horticultural traits. Correlation study indicated that yield per plot was positively correlated with gross and net head weight, seed germination, seed vigour index-I & II, 1000-seeds weight and also showed maximum direct effects towards yield per plot. The path co-efficient analysis revealed that net head weight has maximum positive direct effect on yield per plot followed by gross head weight, days to marketable maturity, seed germination, 1000-seeds weight, head shape index and incidence of sclerotinia rot. While, negative direct effect of number of non-wrapper leaves and incidence of gray mould was observed on yield. The new multicoloured cultivars indigenous and exotic mostly procured from CGN, Netherlands , identified for commercial cultivation under protected conditions in the mid hills of North Western Himalayas, may act as a substitute to the old cultivars with good quality and higher yielding potential.
