Multivariate analyses of rice indigenous germplasm for identification of high yield potential genotypes based on yield and its attributes

The study was carried out to estimate the extent of genetic variability and genetic parameters for yield and yield attributes along with principal components for 112 rice genotypes to determine selection criteria. Genetic variability parameters showed that the phenotypic coefficient of variation was higher than the respective genotypic coefficient of variation and heritability is high for most of the characters. High heritability with high genetic advance as per cent of mean and moderate heritability with high genetic advance as per cent mean observed for the traits indicates the heritability to be of additive nature and selection is effective for improvement of yield in the present breeding material. The principal component analysis revealed a total of five principal components during both seasons based on eigenvalues of more than 1 accounting for 74.76
