Diverse germplasm of guava (Psidium guajava L.) assembled at Horticulture Farm, Maharana Pratap University of Agriculture and Technology; Udaipur was evaluated with respect to morphometric characteristics, yield attributes and quality parameters for further utilization in improvement programme. The 47 guava genotype showed range of variability in respect to plant growth, yield attributes and yield and quality parameters. The average fruit weight ranged from 65 to 281 g, seed content 1.21 to 3.26 g and seed number 125 to 450/fruit in the different genotypes. Further, TSS and ascorbic acid contents ranges from 11 to 18.2 per cent and 129 to 268 mg/100 g pulp respectively. Out of the 47 genotypes two genotypes (MPUAT/47, MPUAT/43 recently named as MPUAT S-1 & MPUAT S-2, respectively) were identified as superior in respect to yield and quality. Further, MPUAT/6 and MPUAT/41 were also observed as potential genotype for the yield. This paper discuss the performance of promising guava genotypes and status of the conservation of guava genotypes in the field repository being maintained and evaluated under sub humid southern plains and Aravalli hills of Rajasthan.
