✦ Synopsis

The triple test cross analysis in rice brought out that significant epistasis is present for most of the characters in the three crosses except for 100 grain weight in two crosses (Co 39 x Co 41) and (Co 39 x Co 40) and plant height in one cross (Co 39 x IR 20) . Epistasis of i' (homozygote x homozygote) for all characters except for plant height and 100 grain weight, j' (homozygote x heterozygote) and `1' (heterozygote x heterozygote) interactions are also detected in all the three crosses . The D component was significant for all the traits in the three crosses and H was significant in cross Co 39 x Co 41 for all characters . For tiller number in cross Co 39 x IR 20 and for tiller number and 100 grain weight in cross Co 39 x Co 40, the H component was not significant . In all the crosses D component was higher than H .
