Abstract

The mode of inheritance of seven quantitative characters, was studied in two redgram crosses by a genetic analysis of the means of six generations, The yield and yield com- ponents showed the predominance of additive gene action and absence of heterosis in Cross, 1 (S. 18 X Prabhat) and a high degree of heterosis conferred by dominance and dominance X dominance effects in Cross. 2 (Cu. 2 x S. 12). Reciprocal recurrent sele- ction seems to be the ideal breeding method for crop improvement in redgram as it results in the simultaneous utilization of epistatic and non-epistatic gene effects.
