“…Seed oil content and its quality Again, highly significant differences in seed oil contents and fatty acid compositions were found among examined sesame genotypes (Table 3), suggesting that sesame genotypes have large genetic variability that allows for the successful selection of favorable genotypes. Mohanty et al (2020) observed similar findings.…”

“…For days to 50% flowering, plant height, seedling dry weight, electrical conductivity, accelerated aging germination, seed oil content, and total saturated/total unsaturated ratio, high heritability combined with moderate (10-20%) expected genetic advance as percent of the mean were recorded, indicating that these traits appear to be controlled by both additive and non-additive gene actions. The variability study of Mohanty et al (2020) indicated high to moderate genetic advance as percent of the mean for traits like plant height, days to first flowering, days to 50% flowering, days to maturity, number of productive branches plant -1 , height of the 1 st capsule, number of productive capsules per plant, number of seeds per capsule, biological yield per plant, harvest index, 1000-seed weight, stearic acid, linolenic acid, linoleic acid, oleic acid, palmitic acid, oil content, oil yield per plant and seed weight plant -1 (g). This study indicates the preponderance of an additive gene effect, which will help to make the selection in an early segregating generation.…”

The identification of genetic variation, mean performance, and selection criteria for twelve sesame genotypes is required for the genetic enhancement of agronomic traits and seed quality. Thus, using a randomized complete block design with three replications, these genotypes were evaluated in a field trial at the Kafr-El-Hamam Agricultural Research Station, Agricultural Research Center, Sharkia Governorate, Egypt, and laboratory experiments at the Seed Technology Research Department, ARC, Giza, Egypt, during the two consecutive seasons of 2018 and 2019. For earliness in flowering, N.A.130 and Shandweel3 were the most promising sesame genotypes, while N.A.114 and RH1F3 had the heaviest weight of seed plant-1 and one or more yield-related traits, and NA114, Shandweel3, and Zahar12 had the best seed quality traits. Furthermore, Shandweel3 and M1A12 had the highest proportion of seed oil, Shandweel3 and Zahar12 had the largest amount of oleic acid, N.A.114 and RH1F3 had the highest content of linoleic acid, and Zahar12 and N.A.114 had the highest proportion of linolenic acid. Seed weight plant-1 can be improved through selecting genotypes having the lengthiest fruiting zone, more branches and capsules, and the high electrical values of seed conductivity, accelerated aging germination as demonstrated by selection criteria. Moreover, the oleic acid proportion had the greatest direct and indirect effect on seed oil content, demonstrating its relevance as sesame oil quality selection criteria.

“…one genotype more than other. These finding are in accept with these obtained by Pavani et al (2020), Singh et al (2020) and Mohanty et al (2020). Furthermore, data in Table (2) showed that except for the length of the fruiting zone, there was a clear interaction between years and genotypes in the traits studied.…”

The present investigation was conducted to determine the genetic behavior of 14 genetically diverse genotypes of sesame in Shandaweel Research Station (ARC), during the two summer seasons of 2017 and 2018, for seed yield and their components using a randomized complete block design with 3 replications. Significant differences among evaluated sesame genotypes for all studied traits were observed. The highest mean values of 1000-seed weight and seed yield/plant were obtained from the genotype M2A23, while the lowest mean value was obtained from the genotype B-42. Number of branches per plant, number of capsules per plant, and seed yield per plant had the highest estimates of PCV and GCV. High heritability combined with the high genetic advance (as a percent of mean) was observed in length of fruiting zone, number of branches/ plants, number of capsules/ plants, and seed yield/ plant, showed that these traits were controlled by additive genetic influences. Seed yield /plant had positive and highly significant correlated with the length of fruiting zone in both branched genotypes and non-branched genotypes. Moreover, length of fruiting zone, number of capsules /plant and 1000-seed weight had great positive direct effects on seed yield/plant. Hence, these characteristics could be helpful in increasing sesame seed yield.

“…This suggests that subjecting these characters to any selection scheme for exploiting fixable genetic variance is highly effective and desirable. Above findings followed the findings of [18] and [19].…”

The present investigation for various genetic parameters was done for twenty-two lowland rice genotypes in R.C.B.D. with three replications at Rice Breeding Section, Pusa Farm, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. Analysis of variance revealed significant differences (P-value =0.01) among genotypes for all the characters. Brasali was the highest yielder suggesting that it can be used for crossing programme for improvement in yield. The phenotypic variance was higher than corresponding genotypic variances for all the characters studied. Genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were highest for grain yield per plant followed by1000 grain weight, plant height, number of panicles, root volume, leaf length and days to 50 % flowering revealing that sufficient variability was present in the gene pool for these characters. Thus, there is ample scope for genetic improvement of these traits through selection. The broad sense heritability ranged from 23 % (panicle length of main axis) to 97% (1000 grain weight). High heritability was obtained for most of the characters except for panicle length of main axis and kernel width. High heritability accompanied with high genetic advance as percent of mean was recorded for days to 50% flowering, plant height, root volume, number of panicles, 1000 grain weight, leaf length and grain yield per plant. High values of GCV, PCV, heritability and genetic advance as percent of mean observed for various characters indicate that these traits can be used as selection indices for yield improvement.
