Abstract:
The experimental material consists of 35 genotypes. Observations recorded on 12 characters and the data obtained was subjected to estimation of genetic Variablity, path and correlation analysis. The estimation of analysis of variance revealed mean sum of square due to genotypes were significant for all the characters indicating sufficient genetic variability among the genotypes. The present study revealed that the phenotypic coefficient of variation was higher than the corresponding genotypic coefficient of variation for all the traits. High PCV and high GCV was observed for plant height. Heritability for broad sense was estimated for all the characters under study and observed range from 61.54 to 99.94%. Genetic advance as percentage of mean ranged from 6.34 to 99.94%. Out of 12 characters, 7 characters showed positive and direct effect with grain yield per plant. A method based on Mahalanobis D2 suggested by Tocher (Rao, 1952) was used to group the genotypes into different clusters based on the D2 values. 35 genotypes were grouped into 10 clusters. As cluster 1 is having maximum number of genotypes (11). Highest percent contribution towards divergence was due to plant height.
