摘　　要： 选取9个蝴蝶兰红花系品种按完全双列杂交进行自交与杂交，共获得5个自交组合与16个杂交组合．总结果率为9．3％，其中自交结果率为22．2％，杂交结果率为7．7％．各组合果荚生长曲线走势大致相同，授粉后7～9d，子房开始膨大，约于50d趋于平稳状态．平均果实采收时间、质量、长及宽分别为（103±4）d，（3．41±0．18）g、（5．50±0．43）cm及（9．37±0．54）mm．果质量、果长、果宽三者之间呈正线性相关． Complete diallel crossing among 9 red cultivars of Phalaenopsis were carried out. 5 self-combinations and 16 cross-combinations were attained. The average fruit set was 9.3%. The mean fruit set of self-combinations and cross-combinations was 22. 2% and 7.7% respectively. The trend of fruit growth curve of each combination was consistent. The size of ovaries was increased from 7 to 9 days and reached their definite size about 50 days after pollination. The average harvest time was （ 103±4） d. The mean fruit mass, length and width were （0. 41 ±0. 18） g, （5.50 ±0. 43） cm and （9.37 ±0. 54） mm respectively. There were positive linear correlations among fruit mass, length and width.
