Abstract:

The triple test cross analysis in brought out that significant epistasis is present for most of the characters in three crosses except primary branches in C-I; days to flowering and number of ridges in C-II; days to 50 per cent flowering and primary branches in C-III. Significant additive × additive epistasis was recorded for fruits per plan, plant height and fruit yield in all the three crosses. while ‘j’(additive × dominant) and ‘l’(dominant × dominant) type epistasis found to be significant for fruit weight, fruit length, fruit diameter, fruits per plant, plant height, nodes per plant and fruit yield in across the crosses. The D and H component were significant for most of the traits in all the three crosses. the (H/D)1/2 except days to 50 per cent flowering, where as it appears significance only for fruit length, fruits per plant and plant height in C-I; fruit weight, estimates was less than unit for most of the traits.
