Genetic variation in sesame (Sesamum indicum L.) landraces of North East India
Moatoshi Jamir, Sapu Changkija and HP Chaturvedi
The analysis of variance revealed significant differences among genotypes indicating high degree of variability in the material taken into account for the investigation. Highest PCV and GCV were recorded for no of capsules per plant, seed yield and test weight and no of primary branches indicating the presence of ample variations for these traits. High estimates of heritability with genetic advance was accounted for 50% flowering, no of primary branches, no of capsules per plant, test weight, oil content and seed yield. Therefore, selection of these traits is likely to accumulate more additive genes leading to further improvements of their performance and these traits maybe used as selection criteria in sesame breeding programme. For seed yield significant positive correlation were observed between, no of primary branches, no of capsules per plant, test weight and oil content indicating relative utility of these traits for selection. Path coefficient analysis revealed that test weight contributed maximum positive direct effect on yield followed by no of capsules per plant, 50% flowering and oil content and also exhibited significant positive correlation with yield indicating the true relationship between the traits suggesting that direct selection of these traits would likely be effective in increasing seed yield.
