Genetic Variability Studies In Colored Pericarp Sorghum (Sorghum bicolor L.)

Abstract

The present investigation entitled “Genetic variability studies in colored pericarp sorghum (Sorghum bicolor (L.) Moench)” was carried out during rabi 2019- 20 at experimental farm of Sorghum research station, VNMKV, Parbhani comprising 81 genotypes to elicit the information on genetic divergence in colored pericarp sorghum and shoot fly tolerance and  nature and degree of genetic variability, heritability, genetic advance as percent mean Observation were recorded on 19 yield and shoot fly characters. Analysis of variance shows that there is considerable difference between the genotypes for all the traits. The result of genetic parameters revealed that moderate to high PCV, GCV, high heritability accompanied with high genetic advance was recorded for all the traits except days to 50% flowering, days to physiological maturity, 100-seed weight, threshability, and leaf angle this suggesting that the selection would be efficient for these characters to bring genetic enhancement in desired way. The traits viz., plant height, number of primaries per panicle, panicle length, panicle width, grain color, fodder yield had high heritability and positive correlation with yield so, simultaneous improvement of these traits along with grain yield is possible by simple selection.
