Abstract:

The exploitation of yield potential through inter sub specific (inter-racial) hybridization become a challenging task for rice breeders. Grain yield improvement is considered to be prime objective of any breeding programme, quality traits are yet another important consideration of rice breeding in India. Association of yield and yield components and among grain quality traits thus assumes a unique prominence as the basis for selecting desirable high yielding genotypes with good grain quality characters. Correlation analysis is basic and foremost effort to find out strategies for plant selection. Hundred grain weight showed significant and negative correlation with grain yield per plant. Linear elongation ratio showed significant and positive correlation with kernel breadth, kernel breadth before cooking, kernel length after cooking, and LB ratio after cooking and hence selection of these traits will serve in improvement of LER. Direct effect of number of productive tillers per plant was found to be high on single plant yield.
