- 摘要:
- 以野生甜瓜‘LCW-01’为父本，栽培甜瓜‘X09-18’为母本进行杂交，观察其杂交后代分枝数、坐果率、单瓜重等20个主要性状的表现，采用ADM模型进行遗传分析，研究杂交后代遗传规律。结果表明：杂交一代基本倾向于亲本遗传，瓜长、单瓜重和肉厚等性状有很大改良空间；正反交F1结果不同，说明存在母体效应。瓜瓤颜色和果肉苦味有无符合孟德尔遗传规律，分别受1对和2对显性基因控制，白色对橘色为显性，苦对不苦为显性；果肉颜色和果肉酸味为受多基因控制的质量性状；分枝数等其余性状为数量性状，不同性状遗传方差分量和遗传力大小不同。
- Abstract:
- In this study,wild melon ‘LCW-01’ was chosen for male and cultivated melon ‘X09-18’ for female.Then,the branch number,fruit-bearing rate,single fruit weight et al.20 total major characteristics of the hybrid progeny were observed.ADM model was used to genetic analysis and study the wild hybrid progeny inheritance.The results showed that the hybrid F1was tended to cultivated parent.The different results of positive and negative F1-hybrid progeny showed that there existed maternal effects.Placenta color and fresh bitter taste complied to mendelism and controlled by one or two pair dominant genes respectively,white to orange as bitter to not bitter was quantities trait.Flesh color and acidity were qualitative traits,controlled by many genes.Whereas the rest traits,branch number for example,were quantitative traits.Because of different traits so the genetic variance components and genetic force size were different.
