The triple test cross analysis carried out in rice for nine Characters revealed the presence of epistasis for most of the characters exceept seed weight per panicle. In the absence of epistasis, additive components (variance for sums) were significant for all the traits while the dominance components (variance for differences) were significant only for six characters. The estimates of additive (D) and dominance (H) components were highly significant for most of the traits, although, the D component was higher than H.
