Abstract

This study examined the genetic variability, heritability, and genetic advance in the F4 generation of sorghum to enhance grain productivity. The study was conducted at Citayam Research Station, Depok Indonesia (March-September 2023), and evaluated 102 progenies of the F4 population from a Bioguma (a mutant line) × Gando Keta (a local variety) cross using an Augmented block design with four replications. The results of this experiment indicated that the F4 generation outperformed the Gando Keta grain yield components, but remained inferior to Bioguma. The yield traits were influenced by the non-additive gene action, with genetic factors playing a significant role in grain weight variation. The top 20% of F4 progenies exhibited improved yield characteristics, including thicker stems, larger panicles, and increased grain weight.
