Abstract
The present investigation entitled “Evaluation of sesame (Sesamum indicum L.) genotypes
for seed yield and other traits under rainfed conditions” was conducted during Kharif, 2016 to
evaluate 24 genotypes of sesame to determine the magnitude of variability for various morphological
and seed quality parameters as well as to study the character association between seed yield and its
contributing traits. Analysis of variance revealed considerable amount of variability among genotypes
for most of the characters under study. Among morphological traits, GCV & PCV were highest for
seed yield per plant and harvest index. High to moderate heritability (broad sense) was recorded for
most of the traits under study while high genetic advance as per cent of mean coupled with high
heritability (broad sense) were observed for number of branches per plant, biological yield per plant,
harvest index and seed yield per plant. Seed yield per plant showed significant and positive correlation
with number of branches per plant, number of capsules per plant, number of seeds per capsule, 1000-
seed weight, biological yield per plant and harvest index while standard germination showed significant
and positive correlation with all the seed quality traits. Harvest index, biological yield per plant,
number of seeds per capsule and number of capsules per plant had positive direct effect on seed yield
per plant. So, combined results of correlation coefficient and path analysis revealed that number of
capsules per plant, number of seeds per capsule, harvest index and biological yield per plant are major
components of seed yield and shoot length, seedling length and seedling vigour index I are major
components of standard germination.
