Title: Heterosis in Relation to Genetic Divergence and Specific Combining Ability in Indian Mustard, Brassica Juncea L. Czern
Abstract: Eighteen parents along with their 45 F1 hybrids were assessed for genetic divergence and heterosis with respect to seed yield and other quantitative characters. The parents and their F|, in general, were distributed in different clusters. There was no correspondence between parental divergence and heterosis exhibited by hybrids. The optimum level of parental divergence to obtain economic heterosis in F1, was provided by the intermediate divergence class. The occurrence of differential frequencies of heterotfc crosses in classes was related to the parental divergence and/or specific combining ability of the crosses.
