Combining Ability and Gene Action Studies in Brinjal (Solanum melongena L.)

Author(s): Patel Arpita A, Gohil DP, Patel NB and Patel DD
Abstract:
The combining ability analysis of a 10 x 10 half diallel set of crosses in brinjal was undertaken for fruit yield and its attributing characters. Ten parents, 45 F1's and one standard check were evaluated at Main Vegetable Research Station, Anand Agricultural University during 2016-17. The analysis of variance revealed presence of considerable variability among genotypes for all the characters under study. Combining ability analysis revealed importance of both additive and non additive variances in expression of various traits. The magnitude of variance due to specific combining ability was higher in comparison to variance due to general combining ability for plant height, number of fruits per plant, fruit yield per plant, dry matter, ascorbic acid, total soluble sugars and acidity suggesting greater role of non-additive genetic variance. Whereas, for rest of the characters predominance of additive gene action involved. Among the parental genotypes, GAOB 2 was good general combiner and GBL1, Doli 5, GP-BRJ-215 and GP-BRJ-216 were average general combiners for fruit yield per plant and were also good/ average general combiners for most of the yield contributing component characters and quality characters. In respect to estimates of specific combining ability effects, for fruit yield per plant, the hybrids GBL 1 × Doli 5, JBL 10-08-07 × GP-BRJ-216, and GAOB 2 x JBL 10-08-01 registered high per se performance and significant high values of sca effects in desired direction for the important yield contributing characters and nutritional quality parameters. Therefore, the above hybrids may be favoured for commercial cultivation as hybrids after critical evaluation over locations. All the parents involved in these crosses had good or average gca effects. Hence, their hybrids are also expected to throw-off transgressive recombinants in segregating generations, combining favourable traits into one genotype for development as improved varieties.
