Non-allelic interaction of some quantitative traits in chickpea

In the present study five generations viz. P1, P2, F1, F2 and F3 of chickpea were taken for the analysis of non-allelic interaction considering five yield and yield contributing characters like as date of first flower (DFF), number of primary branches at first flower (NPBFF), plant height at first flower (PHFF), number of pods per plant (NPd/P) and number of seeds per plant (NS/P). At first Mather’s scaling test was done where scales C and D found to be significant and non-significant for all the traits, respectively. Potence was non-significant for all the characters, which revealed that there was no dominance. In the Cavalli’s joint scaling test, the χ2 values were found to be significant for all the characters, which confirm that additive-dominance model was inadequate and except additive and dominance effects there are other effects like non-allelic interaction, linkage, genotype × environment (G×E) interaction etc. are involved either individually or in combination in the inheritance of the studied traits.
