The nutritional factors and characteristics of sesame (Sesame indicum L.) seeds and extracted oil of six genotypes: G2, G3, G4, G5 and G6 cultivated in Upper Egypt were subjected to comparative evaluation with control (G1), for its genetic diversity, physicochemical properties, fatty acid composition, antioxidant activity and oil oxidative stability (Rancimat test). Estimates of genotypic and phenotypic coefficients of variation revealed high value in seed yield. For heritability estimates, the data showed that four traits out of eight recorded the highest heritability values over of 90%. These traits were oil yield (99.56%), seed yield (98.83%), plant height (96.33%) and seed index (90.03%). Sesame seeds have a high oil content (39.56 to 54.64 g/100g dry weight). The fatty acid profile was varied among the genotypes, in particular oleic acid (37.15 to 46.61%) and linoleic acid (37.49 to 44.33%). Results indicated that G4 has significantly higher in most agricultural traits as well as seed yield, while the G5 was the highest in oil yield and has significantly higher oxidative stability (26.57 h) among the genotypes.

“…This report is in strongly agreed with the findings of Azeez and Morakiny (2014), Reddy et al, (2015), Abdel-Rhman et al (2019) and Chauhan (2019). Involvement of both additive and non-additive gene action for various character was reported by Balla et al, (2014), Sumathi and Muralidharan (2014), Hassan and Sedeck (2015), Anyanga et al, (2016), Tripathy et al, (2016 and Suganthi et al, (2018). This contradictory finding with present research was due to composition of materials handled and the presence of genotype × environment interactions.…”

The study of gene action and combining ability have been conducted in 28 F1 cross combinations along with eight parents in 8x8 half-diallel scheme following Griffing’s Approach for 14 morphoeconomic traits including seed yield and oil content in sesame. The general combining ability (GCA) and specific combining ability (SCA) component of variation were significant for parents and crosses respectively for all characters except internode length for GCA indicating role of both additive and nonadditive gene action. However, higher proportion of SCA variance (?2 sca) than GCA variance (?2 gca) revealed preponderance of non-additive gene action for all characters except capsule length and capsule width under study. Further, variance due to dominance played a significant role than additive variance in all traits except capsule width and 100-seed weight. Nirmala is considered as the best general combiner owing to its higher estimate of gca effects for yield per plant, for days to maturity, plant height, branches per plant, capsules per plant, seeds per capsule, capsule length and 100-seed weight. Among cross combinations; Rama × GT-10, AT-382 × Krishna, AT-382 × Nirmala, Krishna × Nirmala, Krishna × Uma, Nirmala × Prachi and Prachi × Uma showed significantly higher sca effect for seed yield per plant in the desired direction indicating their merit for recovery of transgressive segregants for higher productivity following reciprocal recurrent selection.

“…In contrast, significant negative and GCA effects for this trait were obtained by Shandaweel 2000 and Shandaweel 1 in the two seasons and their combined. Sedeck & Shafie (2013) and Hassan & Sedeck (2015). They found that significant general combining ability effects in some parental lines for some studied traits.…”

HIS RESEARCH work was conducted at Shandaweel Research …. Station, Sohag, Egypt, to study the combing ability and heterosis for yield and its attributes via Line × Tester analysis in sesame. Line × Tester mating design was applied in 2012 season using seven lines and four testers. In the two summers season 2013 and 2014, twentyeight F 1 hybrids, their parents and one commercial variety (Shandaweel 3) as a check were evaluated. Mean squares due to genotypes and years via combined analysis for the two years were highly significant for all studied traits, except each of 1000-seed weight and oil percentage across years. Also, mean squares due to the interaction between genotypes × years were highly significant for all the studied traits, except days to 50% flowering, branches plant -1 and 1000-seed weight. The analysis revealed that high significant differences were found among crosses and lines for all the studied traits over the two years. Likewise, it appeared high significant differences among the four testers for all traits, except for 1000-seed weight. High significant variances were detected for line × tester interaction over years for all studied traits. In this context, results showed that significant and highly significant differences were found for all the studied traits for the interactions; crosses × year (except for length of fruiting zone, branches plant -1 and1000-seed weight), tester × year (except for height of the first capsule, number of branches plant -1 and 1000-seed weight) and parents × crosses × year (except for days to 50% flowering, number of branches plant -1 , capsule length, 1000-seed weight and oil percentage). In general, the four
