Short communication STUDIES ON THE GENETIC ARCHITECTURE OF SOME OKRA CROSSES THROUGH TRIPLE TEST CROSS METHOD

important vegetable crop grown throughnut the country both as summer as well as rainy season crop. Epistasis plays a major role in the inheritance of quantitative traits in okra (Panda and Singh,1998). Consequently, the estimates of additive and dominance components of genetic variation dre biased. Kearsey and Jinks (1968) devised triple test cross (TTC) design to assess the epistasis in controlling the inheritance of traits. The TTC detects epistasis and estimates of additive (D) and dominance (H) components of genetic variance with a high degree of precision using a larger sample of crosses. Therefore, an atlemfJt was made to find out the role of various comfJonents of genetic variance in the inheritance of the eight important traits in okra during summer season using triple test cross analysis. Two okra varieties (HRB-55 and GO-2) and their hybrid (HRB-55 x GO-2) were used as testers and crossed with 20 diverse lines, viz., HRB-107-4, HRB-l08-2
