- Abstract
Estimation of general (GCA) and specific combining ability analysis (SCA) in tomato was performed through line χ tester method using eight lines, four testers and their 32 F1 hybrids. The line, CLN-138 was good general combiner for fruit weight, pericarp thickness, TSS, lycopene and titrable acidity while the line CLN-104 for fruit yield, locules per fruit, fruit shape index, TSS and titrable acidity. Significant GCA effects were for the line CLN-154 for fruit yield, fruit shape index, lycopene and titrable acidity; and tester, LBR-21 for fruit weight, dry matter and TSS. Among the crosses, the combination PVB-1 χ LBR-12 recorded good specific combiner for fruit weight, pericarp thickness and TSS; PVB-1 x LBR-10 for fruit yield, cross CLN-138 χ LBR-21 for dry matter, TSS and lycopene; and cross, PVB- 4 χ LBR-21 for fruit weight, locules per fruit and fruit shape index with significant SCA effects. The estimates of σ2SCA/σ2GCA were recorded greater than unity for all the traits except average fruit weight and ascorbic acid content which clearly indicated the predominance of non-additive gene in these characters.
