以蝴蝶兰P42为母本、P39为父本进行常规杂交,研究其F1代性状的分离情况。结果表明:F1代各性状介于双亲之间或高于或低于双亲,表现为中亲优势或正向超亲优势或负向优势;从频次分布图分析,F1代的优势性状表现在叶数、叶色、花朵数和花色上,其中,花色、花朵数和叶色的变异系数最大,依次为29.16%、28.74%、28.32%,是F1代选择优良单株的重要依据。 Using Phalaenopsis P42 as the female parent and P39 as the male parent, the F1 hybrids were used to study the segregation of F1 traits. The results showed that all the F1 traits between parents were higher or lower than that of their parents, which showed that the F1 progenies had positive or super-positive or negative superiority. According to the frequency distribution analysis, F1 showed the dominant traits in leaf number , Leaf color, flower number and flower color. Among them, the coefficient of variation of flower color, flower number and leaf color were the largest, which were 29.16%, 28.74% and 28.32%, respectively.
