ABSTRACT

Combining ability in eighteen eggplant genotypes were studied at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh during March 2007 to September 2009. Eggplant genotypes were evaluated for different quantitative characters. Highly significant variances due to general combining ability (GCA) and specific combining ability (SCA) for all the studied characters indicated the importance of both additive and non-additive gene actions. The predominance of additive gene action was found for most of the studied characters. Considering GCA effects, the parents P1, P2 and P6 were the good general combiner for number of fruits per plant and yield per plant; P3, P5 and P8 for fruit weight; P4 for fruit length and P3 and P8 for fruit breadth and P1, P6, P2 and P7 for yield per plant. Considering SCA effects, the crosses P5 x P7 were important for fruit length, fruit weight, number of fruits and yield per plant; P5 x P8 for fruit breadth, fruit weight, and yield per plant; P1 x P6 and P2 x P7 for fruit breadth, number of fruit and yield per plant; P1 x P6, P2 x P7, P4 x P7 and P5 x P7 for number of fruits and yield per plant.
