Evaluation of gum content and viscosity profile of different genotypes of guar at different locations

The guar genotypes from different locations were evaluated for gum content and viscosity profile of aqueous guar gum solution. The gum content varied from 26.12 to 31.46 per cent. Genotype RGr-12-1 showed maximum mean gum content of 30.86 percent followed by genotype HGS-563(C) (30.09%). Location wise, Durgapura ranked 1^st in gum content (30.07%) followed by Jodhpur (29.77%). Viscosity varied from 2104 to 6240 mpa.s. Genotype Shakti var-X-6 showed maximum mean viscosity of 5164 mpa.s followed by RGr-12-4 (5068 mpa.s). Location wise, Jodhpur ranked 1^st in viscosity of 4868 mpa.s followed Parbhani by (4781 mpa.s).
