Abstract:
Papaya is a important tropical crop because of tasty flavor, fruit pulp content, its nutritional value and antioxidant properties but needs improvement in resistance to virus, shelf life and fruit quality. Papaya seeds were treated with various doses of gamma radiation to study the mutational influence on the shelf life and fruit quality. The highest reducing sugars were recorded in R10P20 (3.40%), R15P19 (3.95%) and R18P19 (3.00%), R3P19 (3.85%) and R1P13 (3.90%) whereas lowest reducing sugars were observed in R16P18 (3.80%) and R17P18 (3.30%). In M4 selected mutant lines, the highest reducing sugars were recorded in R6P3 (4.15%) and R17P4 (3.50%), whereas the lowest reducing sugars recorded in R7P2 (4.50%). The highest total sugars were recorded in R10P20 (9.11%), whereas lowest total sugars was observed in R16P18 and R17P18 (4.68%). In M2 selected mutant lines, the highest total sugars was observed R2P9 (12.03%), R20P10 (10.79%) and R1P7 (10.30%) whereas, the lowest total sugars% was recorded in R19P12 (6.31%) and R19P21 (6.5%). In M4 selected mutant lines, the highest total sugars% was observed in R18P5 (11.83%), R14P10 (11.30%) R11P5 (10.19) whereas the lowest total sugar percent was recorded in R6P3 (5.98%) and R7P2 (6.20%). The highest titratable acidity were recorded in R18P19 (0.42%), R4P17 (0.77%), R1P13 (0.81%), R19P21 (0.61%), R14P10 (1.77%) and R17P4 (0.74%), whereas the lowest titratable acidity content was recorded in R17P14 (0.16%) and control with 0.17%. the highest ascorbic acid were recorded in R14P19 (59.99 mg/100 g), R14P15 and R13P19 (54.99 mg/100 g) and lowest ascorbic acid content was observed in R11P19 and R15P19 (26.66 mg/100 g). These mutant lines were selected and forwarded to next generation for future mutational studies.
