Abstract
Generation mean analysis and chi-square were attempted to detect the epistasis for yield components and inheritance of growth habit in two crosses of mungbean namely Meha/ DMS 03-17-2 and Meha/ DMS 01-34-2. The study revealed the presence of one or more kinds of epistatic effects were detected for almost all the agro-morphological traits, indicting their complex inheritance nature. The duplicate type of digenic epistatic interaction was observed for most of the agro-morphological traits in both crosses, indicating that the advancement of generations through single seed decent till fixation for accumulating the favourable genes followed by delayed selection might be rewarding. Meha/ DMS 03-17-2 (number of seeds per pod) and Meha/ DMS 01-34-2 (number of secondary branches per plant) may give opportunity to isolate transgressive segregants for respective traits given in prenthesis. The monogenic nature of growth habit in both crosses indicated the possibility for manipulating the traits and to recover/ develop the ideal plant type for mungbean improvement.
