Abstract:
With 3 combinations B×C，K×B and B×I (F1 generation) and its parents B、C、I、K as materials，using ‘Xiaohong’ and ‘Fengzhu’ as contrasts，the main performance and variance of main characters of tomato reciprocal crosses were studied.The results showed that B×I had the highest yield with 1 397.52 kg/667m2，and the single fruit weight was the highest with 9.77 g，significantly higher than that of I and C，fruit setting rate was the highest with 73.84%；vitamin C of B×I was the higher with 7.93 mg/100g，significantly higher than that of I；first inflorescence nodes was the minimum of 5，fruit setting stage was the minimum of 135 d.K×B was better.The yield of parent I was the highest with 1 462.86 kg/667m2，significantly higher than that of C；fruit setting rate reached 83.55%.
