Abstract

To know the combining ability of seed weight in chickpea, five lines namely Co. Coz, CoG4, CoG6 and ICCV2 as females and three testers namely Annigeri, Cos and L 550 as males were crossed in a line x tester model. The effects of the parents and the sca effects of the hybrids were estimated. The estimates of gea revealed that significant and positive effects were observed with CoG4 (5.241), CoG6 (1.627) and ICCV2 (1.775) among lines and with Annigeri (1.468) among testers. The hybrids CoG4 x Annigeri showed high sea effects (2.982), while CoG6 x Co3 (4.028) and ICCV2 x Co3 showed high sea (1.524) with high per se performance. The gca and sca variance ratio showed the preponderance of non-additive gene action for the seed weight in chickpea (0.1734:1).
