Abstract: Grape is genetically highly heterozygous.An early and rapid identification of the authenticity of grape hybrid progenies at the molecular level provides an auxiliary means for accelerating the creation of grape germplasm.SRAP molecular marker technique was used to identify the authenticity of eight F1 seedlings of three hybrid combinations of grape,‘Hongti’בRed Rose’,‘Hongti’בBeda’and‘Hongti’בGuifei’.Ten pairs of primers selected from 196 pairs of SRAP-PCR primers could produce clear and stable polymorphism bands between Hongti and Beda.Among them,four pairs of primers could distinguish between ‘Hongti’ and ‘Red rose’ grape,and 4 pairs of primers between ‘Hongti’ and ‘Guifei’ grape.Three pairs of primers were selected respectively to identify the F1 seedlings of three hybrid combinations,and the results showed that all the eight F1 seedlings were true hybrids.This study provides a basis for the effective and rapid identification of hybrid progenies using SRAP markers.
