 ABSTRACT

Sorghum genotypes were evaluated for genetic variability and interrelationships of characters during Kharif 2013-14 and 2014-15. A significant genotypic variation for all the characters was observed among the accessions. All the characters showed higher phenotypic and genotypic coefficient of variation which indicates that the expression of characters in sorghum population is genetic and can be exploited in sorghum breeding programme. High heritability coupled with high genetic advance was observed for plant height, panicle weight, stover yield and grain yield per plant which indicates that these characters are controlled by additive gene action, so the phenotypic selection for these will be effective. Grain yield was positively correlated with all the characters indicating the effective selection for these characters can be done to improve grain yield. The path coefficient analysis showed a positive and significant correlation as well as high or moderate direct effects of stover yield, plant height, panicle weight, 1000 seed weight on grain yield per plant.
