IDENTIFICATION WILTS RESISTANT WITH HIGH YIELD POTENTIAL OF 86 PROMISING LINES OF SESAME DURING SEASONS 2021/2022

Analysis of variance confirmed genetic variability in both seasons. Besides, Macrophomina phaseolina and Fusarium oxysporum f.sp. sesami Pearson correlation for seasons 2021/2022 demonstrates significant positive correlation between seed yield per plant, number of capsules per plant, flowering date 50%, plant height and height of first capsule. Similarly, there were significant positive correlation between seed yield per plant, number of capsules per plant, capsules length, plant height, flowering date 50%, 1000-seeds weight and height of first capsule. However, plant height exhibited significant negative correlation between capsules length and 1000-seeds weight. Also, significant negative correlation found between wilt %, seed yield per plant and number of capsules per plant. On the other hand, with Macrophomina phaseolina season 2022, wilt % showed significant negative correlation with 1000-seeds weight. Although, in season 2021/2022, wilt % revealed significant negative correlation with flowering date 50% for Fusarium oxysporum f.sp. sesame. Regardless, number of capsules per plant, capsules length and 1000-seeds weight % showed significant negative correlation with capsules length and plant height, respectively. With the exception of Fusarium oxysporum f.sp. sesame, capsules length presented significant negative correlation with plant height and height of first capsule in seasons 2021/2022. In addition, three groups of traits in both seasons presented in heatmap analysis. Furthermore, the ordinate of lines on PC1 and PC2 revealed significantly intercorrelation between each other except lines 85 and 86 in both seasons. Overall, high broad sense heritability suggests presence of large number of fixable additive genes that controls certain traits, which is highly recommended for selection efficiency.
