The physico-chemical characteristics of eight guava genotypes viz. Hisar Safeda, Pant Prabhat, Shweta, Hisar Surkha, L-49, Banaras Round, Allahabad Safeda and HRS Pride were studied at Horticultural Research Station, Orissa University of Agriculture and Technology, Bhubaneswar in both rainy and winter season during 2015-16 and 2016-17.The longest and shortest fruit were obtained in Pant Prabhat and Banaras Round respectively during both the season. Hisar Surkha produced maximum fruit diameter during both the season. The fruit weight was found maximum in Pant Prabhat (147.63 g during rainy and 150.60 g during winter season) and minimum in Banaras Round (106.73 g during rainy season and 112.37 g in Hisar Safeda).During rainy season the specific gravity of the fruit ranged between 0.93 to 0.97 while during winter season it ranged from 0.95 to 0.98 in Pant Prabhat. The TSS: acidity ratio varied significantly with a minimum of 20.60 in L-49 during rainy and 19.18 in Allahabad Safeda during winter to a maximum of 45.06 in Pant Prabhat during rainy and 46.54 in Pant Prabhat during winter season. The highest ascorbic acid was recorded in L-49 (154.67 mg/100 g pulp during rainy and 226.00 mg/100 g pulp during winter season). In respect of qualitative characteristics the varieties like Shweta, Pant Prabhat, HRS Pride were found better compared to the other varieties. The fruits harvested during winter season exhibited better quality than rainy season fruits.
