Assessment of Genetic Variability, Heritability and Genetic Advance for yieldand Quality Attributes in Grain Sorghum

摘要

Fifty sorghum genotypes were studied with objective of estimating the genetic variability, heritability and geneticadvance for yield and quality attributes. The high PCV and GCV value observed for the characters viz., plant height,panicle length, 1000 seed weight, fat content, fibre content, total phenol content, total antioxidant activity, free amino acidcontent and grain yield, whereas low for total carbohydrate content. High heritability coupled with high genetic advancewas observed for all the characters studied except total carbohydrate content is suggesting the predominance of additivetype of gene action in controlling these traits and simple selection would be sufficient for these traits to bring geneticimprovement in desired direction.
