Studies on Genetic Variability, Correlation and Path Analysis in Yellow Pericarp Sorghum [Sorghum bicolor (L.) Moench] Genotypes

The experiment was conducted under rainfed condition at Agricultural Research Station, Madhira during early rabi 2016 using 40 ICRISAT sorghum genotypes. Estimation of variation, phenotypic and genotypic correlations along with path analysis was calculated for the material under study. High amount of variability was recorded in the material for various traits under study. Plant height showed positive significant association with number of leaves per plant, leaf length, leaf width, ear length, straw weight, 100 seed weight and grain yield per plant. Number of leaves per plant showed positive significant association with leaf length, straw weight and number of leaves per plant. Path coefficient analysis revealed that plant height exhibited positive direct effect coupled with positive significant correlation with grain yield per plant. Plant height, number of leaves per plant and 100-seed weight are important characters in deciding the grain yield per plant in the present material under study.
