Evaluation of different papaya genotypes for quality and biochemical changes under middle Gujarat conditions

Abstract

An experiment was conducted at Horticulture research farm, B.A. College of Agriculture, AAU, Anand (Gujarat) to evaluate 12 genotypes, during the year 2014-15 and 2015-16. Results revealed from the pooled base that maximum fruit firmness at the time of harvest and at the time of biochemical analysis was found in genotype V7 (GAP 7). The highest total soluble solids, reducing sugar, non-reducing sugar, total sugar, minimum PLW and maximum shelf life were recorded in genotype V4 (Madhu Bindu).The significantly maximum total carotenoid content was measured in genotype V1 (Pusa Nanha) while, the highest ascorbic acid content was recorded in V8 (GAP 10).Lowest fruit cavity index was observed in genotype V9 (GAP 12) while, minimum fiber content was detected in genotype V6 (GAP 6) .Organoleptically the higher score for taste was observed with genotype V4 (Madhu Bindu) while, higher score for fruit flavour was observed with V9 (GAP 12) and colour was found in genotype V6 (GAP 6). Overall acceptability score was observed higher with genotype V7 (GAP 7).
