Traits Influencing Yield in Sesame (Sesamum indicum L.) and Multilocational Trials of Yield Parameters in some Desirable Plant Types
For ascertaining component (s) maximizing yield, 21 genotypes (parental cultivar and 20 macromutants) of sesame (Sesamum indicum. L., var - B-67, Family: Pedaliaceae) were analyzed based on genetic parameters viz. genetic variability, character association and path analysis considering seven yield related traits (plant height, number of primary branches/plant, total branches/plant, distance from base to first branching, capsules on main axis, total capsules/plant and capsule length) and yield (seed yield/seed protein content/seed fatty oil content) in rainfed kharif season of West Bengal plains. Total capsule per plant is predicted to be the most important selection criterion. For assessment of variation in yield attributes, 6 desirable plant types (parental cultivar and five mutants) were given multilocational trial under four different agroclimatic conditions and the results obtained are discussed and the better plant types are predicted.
