The varieties were taken from Guava demonstration Centre, Bhuna (Fatehabad). They were evaluated on the basis of several physiological paramaters, biochemical parameters and organoleptic ratings. It was observed that there was decrease in moisture content, firmness, ascorbic acid, acidity and pectin content, with the advancement of storage period, during both the seasons, irrespective of cultivars. On the other hand, specific gravity, TSS and TSS: acid ratio was found to be increased with passage of storage time, regardless of cultivars during both the seasons. Among varieties, Hisar Safeda exhibited minimum loss in weight, decay loss and moisture content maximum organoleptic ratings in both the seasons and maximum reducing sugar, specific gravity and firmness in rainy season and also had highest TSS: acid ratio in winter season, while, in rainy season TSS: acid was found maximum in Arka Mridula. Firmness, total sugar, specific gravity and reducing sugar in winter season and TSS in rainy season were recorded maximum in cv. Pant Parbhat. Pectin content during both the seasons and ascorbic acid, total sugar and non-reducing sugar in rainy season was recorded maximum in cv. L-49. Barf Khana had the maximum ascorbic acid in winter season and acidity found minimum in Arka Mridula and Allahabad Safeda in rainy and winter season respectively. It was also observed thatwinter season fruits of all the varieties are much more superior to rainy season fruits.ennullThesis
