ABSTRACT
Cluster bean (Cyamopsis tetragonoloba (L.) Taub.) is a nitrogen-fixing legume has been used as a green manure, forage and as a seed crop. Guar gum, extracted from the pods of the guar plant, is widely used as an emulsifier, thickener and stabiliser in food and cosmetics. Approximately 23% of the guar seed is the gum (galactomannin). With growing international demand for the guar gum, identification or development of suitable varieties for different agro climatic conditions along with high seed yield and quality gum is the pressing need of the hour. To address these issues five guar varieties were evaluated during summer for their yield potential along with biotic factors. The genotype RGC-1017 performed better for biomass, pod number and seed yield as well as showed resistance to cutworm disease. RGC-986 a long duration variety produced high vegetative biomass with good root and shoot system may serve as a dual purpose variety for fodder and seed.
