蝴蝶兰杂交育种技术的初步研究

Preliminary Study on the Cross-breeding Technique of Butterfly Orchid(Phalaenopsis amabilis Bl)

选取7个蝴蝶兰品种进行自交与杂交,共获得3个自交组合与9个杂交组合。各组合授粉后7～9 d子房开始膨大,约于50 d左右蒴果大小趋于平稳状态,140～150 d采摘接种。通过观察得出,红天使×白天杂交组合的生长势指数最高,金色兄弟×红天使杂交组合的生长势指数最低。不同杂交组合的最佳采摘期有所差别。

7 cultivars of Phalaenopsis amabilis B1 were chosen to self-bred and cross-bred and 3 self-combinations and 9 cross-combinations were obtained. After 7 to 9 days,the ovary of each combination which was pollinated began to inflate, and the capsule＇s size tended to stable state after 50 days. After 140 to 150 days, the capsule was picked and inoculated. It was showed that the growing power index of cross-comblnation＂Red Angel＂＂White Angel＂was the highest,and those of ＂Golden Brother＂＂Red Angel＂was the lowest. The best picking-period of distinct cross-combination was different.
