Abstract: For improving the shelf-life of melon fruit, the experiment was conducted to evaluate the inheritances of ethylene production, abscission of peduncle and rapid yellowing of epidermis in melons. Queen×9-8 (within non-climacteric melons) and Queen×Charentais (among non-climacteric and climacteric melons) including their F1, F2 and BC generations were obtained from these three varieties with contrasting ethylene production and rate of change. Results showed that inheritance of ethylene production in melon was of incomplete dominance mode, and controlled by more than two genes. Internal ethylene concentration in F1 generation of Queen×Charentais displayed a great rise at one day after harvest and companied with abscission of peduncle and rapid yellowing of epidermis. The different segregation ratios in F2 and BC generations suggested that the inheritances of these characters were of dominance mode. Shelf-life of melons can be improved by back-crossing with low ethylene parent at early stages.
