Abstract:

An experiment was carried out with 30 basmati genotypes including 3 checks, were raised in randomized block design with three replications, to determine the inter-relationships among yield components and their direct and indirect contributions towards seed yield. The genotypic correlation coefficients were higher in magnitude than phenotypic correlation coefficients which revealed a strong inherent association between various characters under study and the phenotypic expression of correlations was lessened under the influence of environment. Grain yield per plant had a significantly positive correlation with spikelet per panicle, grains per panicle and fertility per cent. Grain length had positive and significant correlation with grain length after cooking, grain breadth and L: B ratio indicating typical basmati character that basmati varieties elongate length wise. Path analysis revealed that grains per panicle had a maximum direct effect on grain yield per plant followed by tillers per plant and 1000-grain weight. Therefore selection based on these characters either in combination or alone will help in improving basmati cultivars.
