Generation mean analysis using ten parameters (m, [d], [h], [i], [j], [l], [w], [x], [y] and [z]) was carried out to assess the presence of inter-allelic interaction and to estimate the importance of various gene effects for inheritance of twelve generations, namely P1, P2, F1, F2, B1, B2, B11, B12, B21, B22, B1s and B2s of three crosses of brinjal viz., JBG-10-208 x   GOB-1 (cross 1), NSR-1 x GBL-1 (cross 2) and JB-12-06 x Pant Rituraj (cross 3) for twelve characters in brinjal viz., days to opening of first flower, days to first picking, fruit length (cm), fruit girth (cm), fruit weight (g), number of fruit per plant, number of branches per plant, plant height (cm), total fruit yield per plant (kg), plant spread (cm), total soluble solids (°B) and fruit borer infestation (%). Experiment was laid-out in Compact Family Block Design (CFBD) with three replications. The crosses and the traits which were found significant digenic interaction (weighted least square technique) subjected to trigenic ten-parameter model. The trigenic ten-parameter model was found significant χ2 values with two degrees of freedom for all the traits in all the three crosses showing the presence of higher order epistasis and /or linkage. Besides this, all ten-parameters were significant for fruit weight, plant spread and fruit borer infestation in all the crosses; fruit girth in JBG-10-208 x GOB-1; number of fruits per plant in JBG-10-208 x GOB-1 and NSR-1 x GBL-1; total fruit yield per plant in JBG-10-208 x GOB-1 and JB-12-06 x Pant Rituraj and total soluble solids in NSR-1 x GBL-1 and JB-12-06 x Pant Rituraj. Duplicate epistasis was observed in all the crosses for all the traits except for fruit girth in NSR-1 × GBL-1 (cross 2) and number of fruits per plant in JB-12-06 × Pant Rituraj (cross 3).

Key words: Brinjal, gene action, epistasis, generation mean analysis
