Sorghum (Sorghum bicolor (L.) Moench, a climate-resilient C4 cereal, is essential for producing food and fodder in arid and semi-arid areas. Yellow pericarp genotypes, recognized for their elevated flavanone and phenolic levels, have undergone minimal genetic assessment. This research evaluated fifty two yellow sorghum genotypes in the Rabi 2024 season at ARS, Tandur, PJTAU, utilizing a randomized block design to examine genetic variability, heritability, among traits. Notable differences (p<0.01) were detected among genotypes for every trait, signifying extensive genetic diversity. A high heritability was observed for days to 50% flowering (94.80%), days to maturity (94.10%), test weight (87.00%), and the number of grains per panicle (84.40%). Characteristics like test weight (GCV: 14.79%, PCV: 15.86%) and panicle width (GCV: 14.53%, PCV: 17.68%) exhibited significant genetic progress as a percentage of the mean (28.44% and 24.62%, respectively), indicating robust additive genetic influence. These results emphasize the promise of essential yield-influencing characteristics for selection, aiding the creation of high-yielding yellow sorghum varieties with enhanced yield and nutritional value for sustainable farming.
