The agronomic performance of inter-cultivar hybrids of Brassica rapa L. was studied in crosses between four B. rapa cultivars. Six reciprocal hybrid combinations were produced by hand pollination in the greenhouse. Hybrids and their parents were tested in replicated yield tests for 3 yr. An average, over all hybrid combinations, of 13% heterosis for seed yield was observed. Heterosis for seed yield was greatest in crosses between genetically diverse cultivars, which agrees with classical theories on heterosis. There were also significant differences in yield of reciprocal F1 combinations. Seed oil content was not heterotic. The results of this study indicated that the level of heterosis of seed yield in crosses between B. rapa cultivars adapted for production in western Canada is sufficient to warrant the development of a suitable pollination control system for hybrid B. rapa production.

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.

Westar summer rape (Brassica napus L.), licensed in 1982, is a canola-quality cultivar that combines high seed yield with high oil content and early maturity. Westar is adapted to the B. napus growing areas of western Canada and because of its superior agronomic performance has replaced the older cultivars Regent, Andor and Altex.Key words: Rape (summer), cultivar description

AbstractSimultaneously identify superior performing in terms of seed yield and seed oil content and broad adaptation across a wide range of different environments is an important target for sunflower breeder. So, 10 sunflower genotypes were evaluated across the eight various environments created by sowing at four locations i. e. Kafr El Hamam/ Sharkia, Shandaweel /Sohag, Tag El Ezz/ Dakahlia and Al Arish/ North Sinai Agricultural Research Stations, Agricultural Research Center (ARC), Egypt during the two successive summer seasons 2018 and 2019 using randomized complete block designs with four replications in each environment. Results showed that mean squares due to environments, genotypes and their interaction were highly significant for seed yield and seed oil content. Most stability approaches revealed that high performing stable genotypes were L240 for seed yield and Sakha 53, L110 and L235 for seed oil content under divergent environments. Hence, these four stable sunflower genotypes could be behaved as good breeding materials stock for sunflower improvement.

SUMMARYThe response of sesame to fertilizer was studied in 11 trials at four different sites, in which phosphorus was applied at rates from 0 to 26 kg ha−1 to the seed bed and nitrogen at rates from 0 to 60 kg ha−1 after thinning. Yield responses, found only to the main effects of nitrogen and phosphorus, are discussed in relation to soil type and previous cropping history of the sites and used to calculate gross cash returns from fertilizer use. Seed oil content was affected by environment, but responses to nitrogen and phosphorus were inconsistent.

Tribute summer rape (Brassica napus L.), registered in 1985, is a triazine-tolerant, canola-quality cultivar. It is early maturing and produces seed with low seed chlorophyll content. Tribute has yield and seed oil content similar to other triazine-tolerant cultivars such as OAC Triton. Tribute is better adapted than OAC Triton to the B. napus growing areas of western Canada because of its earlier maturity. However, it should not be planted on fields which have a history of heavy blackleg infestations. Key words: Rape (summer), triazine-tolerant, cultivar description
