NATURE OF ASSOCIATION AMONG SOME QUANTITATIVE TRAITS IN WILD RICE

Abstract

Twenty genotypes comprised of three wild species of rice were studied for correlation among sixteen characters i.e. Plant height, number of tillers, test weight, number of internodes, number of leaves, length of leaf, number of spikelets, length of spikelets, length of anther, length of stigma, pollen viability, pollen size, length of awn, seed setting, yield and germination percentage. Correlations between grain yield and each of sixteen characters were partitioned into direct and indirect effects. Number of spikelets per panicle was the most important character in exerting maximum direct effect on yield.
