项目摘要

The relationship among rain lilies (Zephyranthes, Habranthus and Rhodophiala) presumed from the electrophoretic patterns of isozymes, cross affinity relationship and morphorogical characteristics. The materials used in this experiment were 5 species and 8 cultivars of Zephyranthes, 3 species and 5 cultivars of Habranthus, and 1 species of Rhodophiala. The results are as follows.1) According to the result of dendrogram on cluster analysis by the electrophoretic patterns of esterase, peroxidase and acid phoshpotase isozymes, Z.'Luciae' is close to Habranthus, and Rhodophiala is remote from Zephyranthes and Habranthus.2) Intervarietal, interspecific and intergeneric crossing was carried out using the ovule and ovary culture technique, Though most of F1 plants were matroclinal plants, true hybrids obtained from some cross combinations. Therefore, a great number of crossing should be made in order to obtain hybrid seeds.3) The direction of bloomed flowers differ greately between Zephyranthes and Habranthus. The flower face upwardly in Zephranthes, but face of obliquely in Habranthus.4) In parents and F_1 plants, flower color was investigated with Hunter's color difference meter. A wide variation of flower color was observed among F_1 plants. These materials could be used for the improvement of flower color in the rain lily.

从同工酶的电泳图谱、交叉亲和关系和形态特征推测了雨百合（Zephyranthes、Habranthus和Rhodophiala）的亲缘关系。本试验所用的材料为泽兰属5种8个品种，玫瑰花属3种5个品种，红瓶霉属1种。结果表明：1）根据酯酶、过氧化物酶和酸性磷酸酶同工酶电泳图谱聚类分析结果，将Z. 2）利用胚珠和子房培养技术进行了品种间、种间和属间杂交，虽然F1代大多数植株为偏母植株，但也有部分杂交组合获得了真正的杂种。因此，要获得杂交种子，必须进行大量的杂交。3）蝴蝶兰和玫瑰花的开花方向差异较大。4）用Hunter色差计对亲本和F_1代植株的花色进行了测定。F_1代花色变异较大。这些材料可用于改良百合花色。
