Abstract

Abstract: Combining ability and heterosis studies were performed for in vivo and in vitro traits in a diallel cross involving seven tomato breeding lines. Mean squares of genotypes, parents and resuled twenty one hybrid combinations were found to be highly significant for all in vivo and in vitro studied traits. Mean square estimates of parent vs. crosses were found to be highly significant for all studied traits except plant heigh,early yield, callus induction and callus fresh weight. Both general (GCA) and specific combining ability (SCA) variances were found to be highly significant for all in vivo and in vitro studied traits. The GCA/SCA ratios were found to be less than unity for number of cluster per plant, earliness of flower, callus induction, callus fresh weight and callus dry weight. The line (P3) was considered to be good general combiner for all traits except fruit weigh, early yield, T.S.S and callus induction. The correlation coefficient was positive and highly significant between in vitro and in vivo characters. Information generated from this study can be useful for selecting parents and hybrids to maximize the yield and its components in tomato.
