Abstract:
Twenty-five genotypes of sesame were evaluated in a field to study the magnitude of genetic variability, heritability and genetic advance for seed yield and yield contributing traits. The analysis of variance revealed that there were highly significant for all characters studied. Days to 50 percent flowering, plant height, number of primary branches per plant, number of capsules per plant, number of seeds per capsule, capsule length, capsule width, 1000 seed weight, days to maturity and seed yield per plant. The phenotypic coefficient of variation was greater than genotypic coefficient of variation for all the character studied which shows the influence of the environment effect on the characters. Moderate values for phenotypic coefficient and genotypic coefficient was recorded for the traits viz., number of primary branches per plant, number of capsule per plant and number of seeds per capsule. High heritability and high genetic advance was recorded for characters viz., number of primary branches per plant indicating that these characters were controlled by additive gene effects. High heritability with moderate genetic advance was shown for plant height, number of capsules per plant, number of seeds per capsule, capsule length, capsule width and 1000 seed weight. Moderate heritability coupled with moderate genetic advance was observed for seed yield per plant.
