Abstract: Six cucumber inbred lines were used as materials in the experiment.This paper studied the combining ability and heritability of photosynthetic light compensation point,net photosynthetic rate and night respiratory rate by using complete diallel crossing value of tolerance-weak-light and two hybrids were better than others.The results showed that the broad heritability of photosynthetic light compensation point and net photosynthetic rate under 25℃ is separately 71.75% and 73.62%,the narrow heritability of that is separately 21.42% and 0.The broad heritability and narrow heritability of night respiratory rate is separately 49.77% and 20.59%.

Key words: Cucumber seedling, Weak light, Photosynthetic light compensation point, Net photosynthetic rate, Night respiratory rate, heritability
