Genetic variability and interrelationship among biochemical traits of Indian clusterbean (Cyamopsis tetragonoloba (L.) Taub.) germplasm
Abstract
Forty two Indian clusterbean genotypes were subjected to biochemical characterization. Biochemical profiling revealed the presence of ample amount of variation for crude protein, crude fibre, crude fat, ash, carbohydrate and guar gum content. Correlation analysis among the profiles expressed crude fibre positively and significantly correlated with ash content, but negatively and significantly correlated with crude protein. Carbohydrate showed significant and negative correlation with crude protein. Gum content showed positive and significant correlation with crude protein, but negative association with ash and carbohydrate content. High crude fat and ash content was found in the genotypes namely Amrit11, PNB, HVG2-30, T local and M local. These genotypes can be used for vegetable purpose as their length of the pod is higher than other genotypes. The genotype HFG119 has recorded high crude fat, ash and fibre content, which are the reasons attributed for the suitability as a fodder. Genotypes namely HGS16, RGC 1066, RGC1033, GAU 513, HGS870, MRSG6, RGM 1, RGC1002, SRG1008 suitable for gum extraction, after that they can be used for guar meal. Clustering based on proximate analysis distinguished the entire genotypes into gum producing and non gum producing genotypes.
