Study on genetic variability and correlation of morpho-agronomic characters with protein and carbohydrate contents in rice bean

An investigation was carried out with a set of 50 germplasm lines of rice bean procured from different parts of Nagaland to study their genetic variability along with correlation analysis of morpho-agronomic characters with contents of protein and carbohydrate. The significant mean sum of squares due to genotypes indicated the existence of a wide range of variability among the various germplasm lines. Carbohydrate content showed positive and significant correlations with most of the traits under study unlike that of protein, which exhibited negative correlations.
