Abstract:

Character association was studied in the present investigation, to assess the relationships among yield, its components for enhancing the usefulness of selection. Genotypic correlations reveal the existence of real associations. The study of character association among the yield components revealed the significantly positive association of grain yield with Anthesis silking interval, ear length, ear girth, number of kernel rows per ear, number of kernels per row, 100-kernel weight, shelling percentage, crude protein, tryptophan and lysine while, significantly negative associations were recorded with days to 50 per cent anthesis, days to 50 per cent silking, and days to maturity whereas, positive non-significant associations were registered for plant height, ear height and tryptophan contents. The study of character association among the yield components revealed the significantly positive association of grain yield with Anthesis silking interval, ear length, ear girth, number of kernel rows per ear, number of kernels per row, 100-kernel weight, shelling percentage, crude protein, tryptophan and lysine while, significantly negative associations were recorded with days to 50 per cent anthesis, days to 50 per cent silking, and days to maturity whereas, positive non-significant associations were registered for plant height, ear height and tryptophan contents. Path coefficient analysis revealed that shelling percentage, ear girth and lysine at Adilabad exhibited the highest positive direct effects and hence these traits play an important role in generating the high yielding genotypes in the future breeding programmes.
