Abstract: The present investigation was undertaken with a view to generate genetic information on gene effects for 12 quantitative traits in brinjal through generation mean analysis. The experimental materials comprise of six basic generations viz., P1, P2, F1, F2, BC1 and BC2 of four crosses of brinjal viz, AB-8-14 x S. Mani Black (cross 1), AB-15-07 x Pant Rituraj (cross 2), JB-12-06 x GJB-3 (cross 3) and NBR-14-1 x GJLB-4 (cross 4). The results indicated that the magnitude and type of gene effects differed for the same trait in different cross combinations. Therefore, for the improvement of particular trait, segregating generations of individual crosses should be handled according to the gene action involved in its inheritance. Additive [d], dominance [h], additive x additive [i], additive x dominance [j] and dominance x dominance [l] gene actions were equally important for days to first flowering in cross NBR-14-1 x GJLB-4, fruit length in cross NBR-14-1 x GJLB-4, fruit weight in crosses AB-15-07 x Pant Rituraj and NBR-14-1 x GJLB-4, plant spread in cross NBR-14-1 x GJLB-4, TSS in cross AB-8-14 x S. Mani Black. Classification of gene action showed importance of duplicate type of gene action for most of the characters in most of the crosses. Breeding procedure involving multiple crosses, bi-parental crosses may be restored to get transgressive segregants. This is especially important to develop inbred lines having superiority in different characters. Such lines can give better hybrids. While in case of complementary type of epistasis, material can be utilized directly in breeding programme.
