| 摘 要： | 以月季（Rosa spp.）品种‘云蒸霞蔚’和‘太阳城’正交获得的184株F1代群体为研究对象，采用方差分析、变异系数、遗传分析、相关性分析对花部形态性状以及叶片形态性状进行测定分析。结果表明：该杂交群体表型变异丰富，变异系数在7.33%~68.08%，其中花瓣数量在群体中的变异程度最高；杂交后代各个性状上均发生分离变异，出现不同于亲本的表现型，且离散程度较高。表型性状的遗传特点与关联分析，为挖掘控制表型性状的优良基因及辅助选择育种提供参考。

| Abstract: | Heredity of some characters of flower and leaf in F1 individuals of mother(Rosa ‘Yunzheng Xiawei’) and father(R. ‘Sun City’) were measured and analyzed with variance, coefficient of variation, inheritance and correlation. The coefficient of variation in the hybrid population was 7.33%-68.08%, indicating a significant phenotypic variation. Among them, the number of petals in the population showed the highest degree of variation. All the traits measured had high degree of dispersion and came out new phenotypic traits, different from parents. The analysis of the genetic characteristics and correlation of phenotypic traits will benefit for selecting breeding and assisting breeding for dominant genes in controlling phenotypic traits. |
