摘　　要：[Objectives]This study was conducted to investigate the inheritance laws of'Meiting'nectarine.[Methods]With'Meiting'nectarine as the material,the inheritance of the main traits was studied,and the genotypes were inferred.[Results]The two paired traits,freestone and tree height,segregated in the self-bred progenies of'Meiting'nectarine,and the segregation ratio was basically in line with Mendel's independent allocation rule of a pair of gene traits of 3:1,indicating that these two pairs of genes are heterozygous.The round fruit,glabrous fruit surface,yellow flesh,rose-shaped flower,pollen,inseparable flesh and skin,half-opened tree shape,straight leaf edge and kidney-shaped leaf nectary did not segregated in the progenies,indicating that these traits are homozygous.Based on the above results,the genotypes of the main traits of'Meiting'nectarine were inferred.[Conclusions]This study provides a theoretical basis for peach parent selection,thereby improving breeding efficiency.
