Abstract
Experiments were carried out at Field Crop Dept., College of Agric., Univ. of Baghdad, during spring and fall seasons of 2013. The objectives were to estimate the:1- Phenotypic, genotypic and environmental variations, 2- Genotypic and phenotypic coefficient of variation and 3- broad sense heritability for seven traits days to 50% anthesis (DTA), plant height (PH), leaf area (LA), panicle length (PL), panicle weight (PW), crop growth rate (CGR), and grain yield per plant (GY). These traits and variances were recorded on three genotypes of sorghum (Sorghum bicolor L. Moench), Enqath, Rabih, and Kaffier. Results of statistical analysis showed that most traits had higher genotypic and phenotypic variances than environmental variance estimate, which indicated these traits were genotypic origin, and can be exploited in breeding programs. The genotypes exhibited varying degrees ratios of heritability for most traits. Such traits were responded positively to selection due to high broad sense heritability estimates. These data demonstrated high diversity for the traits studied of genotypes used.
