Genetic Analysis in an F2 Population Derived from Indonesian Local Sorghum with New Superior Variety

Genetic analysis and inheritance patterns studies on agronomic yield characters were required to develop a plant breeding program. This study aimed obtain information performance, gene action, genetic diversity, heritability in the F2 population derived from crosses of local high-yielding varieties. The was conducted August-November 2021 Dramaga, Bogor. sorghum population, female male parents, also ten check genotypes used this study. results showed qualitative indicated parent trait strongly inherited F2. A few genes controlled quantitative via additive action for days flowering, height, stem diameter, leaf length, panicle length wet dry weight. Meanwhile, number width, grain weight per by complementary epistasis. had significant positive correlation (0.9 0.95) with although there low h2bs (0%). Panicle diameter could be as indirect selection because their (0.67 0.7) high (90 80%).
