摘要: 根据3种类型梨杂交组合后代的遗传表现,提出梨果实肉质遗传模式为:梨果实肉质的脆软肉遗传为质量性状遗传,由A、B两对基因控制。软肉对脆肉为显性,只有两对基因同时隐性纯合时才表现为脆肉。脆肉基因型为aa bb,软肉基因型为A_ _ _、_ _B_,该模式可解释前人的部分研究成果。
Abstract:The crispness and softness of flesh texture in pear are qualitative characters,controlled by two genes A,B.The softness is dominant to crispness,only when two genes are recessive homozygous,the phenotype is crispness.The genotype of crispness is aabb,the genotypes of softness are A_ _ _,_ _ B_,Some factors may affect flesh also.
