GENETIC PARAMETERS OF YIELD AND YIELD COMPONENTS POOLED OVER ENVIRONMENTS IN SESAMUM (SESAMUM INDICUM L.)

ABSTRACT

An investigation was carried out to assess the genetic parameters i.e variability, heritability and genetic advance for nine characters viz., plant height, days to 50% flowering, number of primaries, number of secondaries, number of capsules per plant, number of seeds per capsule, 1000 seed weight, oil content and seed yield plant in 10 genotypes over six environments during Kharif, 2010 and Rabi 2010-11. Significant differences were observed for all the characters among the genotypes studied for pooled analysis of six environments. The results revealed that high GCV and PCV were observed  for the characters viz., seed yield per plant, number of capsules per plant, number of secondaries per plant and number of seeds per capsule in the pooled analysis of six environments studied. The characters seed yield per plant, number of secondaries, number of seeds per capsule and number of capsules per plant had shown high heritability accompanied by high genetic advance over pooled environments. The traits number of capsules per plant, number of seeds per capsule, seed yield per plant,  and number of secondaries are found little influenced by environment.
