High PCV and GCV were also reported by Parameshwarappa et al (2009), Gidey et al (2013), Patil and Lokesha (2018) and Sudhakar et al (2007) for yield per plant, Parameshwarappa et al (2009), Gidey et al (2013) and Dash et al (2018) for the number of capsules per plant and Sudhakar et al (2007) for the number of branches per plant. It indicated that these traits had a greater diversity.…”

“…High heritability combined with high genetic advance as per cent of mean was recorded for the number of branches per plant (Bharathi et al 2014a. and Patil and Lokesha, 2018 and 1000 seed weight , Patil and Lokesha, 2018, Gidey et al 2013 indicating that these traits were governed by an additive gene action and have better scope for crop improvement. The traits such as the number of capsules per plant and yield per plant exhibited moderate heritability along with high genetic advance.…”

The present study was carried out in the F 2 population of the cross OMT 21 A × JLSC 96 of sesame with the objective to assess the genetic variability, character association of yield and yield related traits in sesame. Experimental materials were raised during Kharif season of 2019 at Tamil Nadu Agricultural University, Coimbatore. Seven biometrical traits viz., days to first flowering, plant height, the number of branches per plant, the number of capsules per plant, the number of seeds per capsule, 1000 seed weight and yield per plant were recorded. The magnitude of PCV and GCV values were higher for the traits yield per plant, the number of branches per plant and the number of capsules per plant. The traits number of branches per plant and 1000 seed weight exhibited a high heritability along with a high genetic advance as per cent of mean. Yield per plant had a significant positive correlation with the number of capsules per plant followed by 1000 seed weight, plant height and the number of branches per plant. Path analysis revealed that the number of capsules per plant had a high positive direct effect on yield per plant. So, the selection based on these traits such as number of capsules per plant, plant height, 1000 seed weight and the number of branches per plant would be advantageous for crop improvement.

The present study was aimed to gather information on genetic association of traits with respect to seed yield and its components. The genotypes were planted in 9 × 9 simple lattice designs at Melkassa Agricultural Research Center, Ethiopia, during the 2014 cropping season to determine the nature and extent of phenotypic and genotypic correlation and path coefficient analysis among 13 quantitative traits. Analysis of variance revealed significant difference among genotypes for all traits studied. Mean performance of genotypes revealed that the highest mean seed yield/plant (8.6g) recorded for Oromia-22 and the lowest mean seed yield/plant (2.6g) for Oromia-9; with overall mean of 5.33g/plant. Whereas, the highest mean oil content (52.15%) noted for Oromia-13 and the lowest (43.35%) mean oil content was recorded for Am-SW-7 genotypes; with overall mean of 47.1%. Traits viz., number of capsules, biomass yield, harvest index and 1000 seed weight showed highly significant and high positive correlation with seed yield, indicating that these traits are reliable yield components and seed yield can be improved through direct selection of them. Moreover, plant height and number of seeds/capsule showed highly significant but moderately positive correlation with seed yield; hence, these trait scan also be considered alternatively for yield improvement in sesame. Maximum positive direct effect on seed yield was exerted by number of capsules, biomass yield, and days to maturity and harvest index, suggesting that these traits can be used for selection to improve the primary trait. Over all, the use of the above mentioned traits in sesame improvement program (of the mid-altitude areas of Ethiopia) would increase seed yield.

The current investigation was aimed to study the genetic association of seed yield and its components in 81 mid-altitude sesame accessions based on morphological traits. The genotypes were evaluated in 9 × 9 simple lattice design at Melkassa Agricultural Research Center, Ethiopia, during the 2014 cropping season. The study mainly focused on determining the nature and extent of phenotypic and genotypic correlation and path coefficient analysis among 13 quantitative traits. Analysis of variance revealed significant difference among genotypes for all traits studied. Mean performance of genotypes revealed that the highest mean seed yield/plant (8.6 g) recorded for Oromia-22 and the lowest mean seed yield/plant (2.6g) for Oromia-9; with overall mean of 5.33 g/plant. Whereas, the highest mean oil content (52.15%) noted for Oromia-13 and the lowest (43.35%) mean oil content was recorded for Am-SW-7 genotypes, with overall mean of 47.1%. Characters viz., number of capsules, biomass yield, harvest index and 1000 seed weight showed highly significant and high positive correlation with seed yield. Plant height and number of seeds/capsule also showed highly significant but moderately positive significant association with seed yield; indicating that these traits are reliable yield components and seed yield can be improved through direct selection of these traits. Maximum positive direct effect on seed yield was exerted by number of capsules, biomass yield, days to maturity and harvest index; showing that these traits can be used for selection to improve the primary trait. Hence, the use of these traits in sesame improvement program would increase seed yield.
