Abstract

A mapping population segregating for the important nutritional quality traits (protein content, oil content and fatty acid profile) was evaluated for genetic variability and correlation among the traits. The population exhibited significant variation among the genotypes, seasons and G x E interaction. Moderate magnitude of variability followed by higher heritability was observed for most of the quality traits. Positive correlation was observed between protein and oil content, whereas, negative correlation between oleic and linoleic acid indicated their antagonistic nature. All the eight fatty acids were correlated with each other either positively or negatively. Superior RILs were identified for higher protein content, oil content, oleic acid and O/L ratio from the population.

Keywords
