Genetic diversity for morphophysiological character studies in rainfed sorghum (Sorghum bicolor[L.] Moench) parental lines

The experimental trial was conducted at Sorghum Research Centre, Marathwada Agricultural University, Parbhani during kharif 2021 in randomized design with 3 replications. Eighteen parental (B & R) lines were evaluated to study genetic diversities and variability for fifteen yield contributing characters. Among all the eighteen genotypes of significant differences observed its traits except total chlorophyll content. Coefficient variance phenotypic level showed higher values than genotypic among traits. like stability index (G=23.035, P=23.714), leaf area (G=21.064, P=21.673), 1000 grain weight (G=28.845, P=29.929), fodder (G=21.858, P=22.458), number per panicle (G=29.564, P=30.158), dry (G=29.044, P=29.903) high both level. Traits plant height (H=90, GAM=21.041), (H=86, GAM=29.074), (H=94, GAM=23.664), GAM=42.17), GAM=46.093), (H=96, GAM=59.703), GAM=43.823),1000 (H=92, GAM=52.270) harvest (H=84, GAM=32.321) recorded heritability advancement. Genotype AKR 504, NR 39-15, KR 218, 219, PMS 100B, AKMS 90 B INDORE 12 better performance characters thus, should be used development hybrids inbreds breeding programmes by DUS (Distinctness, Uniformity Stability) testing.
