Assessing genetic variability and heritability in the F<sub>4 </sub>population of mutant Bioguma and Gando Keta local Indonesian sorghum [Sorghum bicolor (L.) Moench]
This study examined the genetic variability, heritability, and genetic advance inthe F<sub>4 </sub>generation ofsorghum toenhance grain productivity. The study was conducted atCitayam Research Station, Depok Indonesia (March–September 2023), and evaluated 102 progenies ofthe F<sub>4</sub>population from aBioguma (amutant line) Gando Keta (alocal variety) cross using anAugmented block design with four replications. The results ofthis experiment indicated that the F<sub>4</sub>generation outperformed the Gando Keta grain yield components, but remained inferior toBioguma. The yield traits were influenced bythe non-additive gene action, with genetic factors playing asignificant role ingrain weight variation. The top 20% ofF<sub>4</sub>progenies exhibited improved yield characteristics, including thicker stems, larger panicles, and increased grain weight.
