Abstract: Field experiment was conducted during kharif, 2015-16 at Dry land farm, on sandy loam soils of Sri Venkateswara Agricultural College, Tirupati situated in Southern Agro-Climatic Zone of Andhra Pradesh. The experiment was layout in randomized block design with ten treatments and three replications. Ten guar genotypes were evaluated. The results revealed that there was significant difference between the varieties for plant height, number of branches, total dry matter and leaf area. Among the ten guar genotypes, RGC-986 recorded higher morphological traits viz. plant height and number of branches. However RGG-13-4 and RGG-12-3 recorded higher dry matter accumulation and leaf area compared to other genotypes. The physiological traits CGR, NAR, LAI and total chlorophyll contents were significantly higher in RGG-13-4 and RGG-12-3 genotypes compared to all other genotypes. Correlation studies revealed that seed yield recorded positive correlations with dry matter (R² = 0.495) and leaf area index (R² = 0.254).
