In order to breeding new potato (Solanum tuberosum) varieties with antiRhizoctonia solani,high yield and good quality,‘Longshu No.6’ and ‘Longshu No.7’ was crossed with ‘Atlantic’,respectively,and the F₁ hybrids were obtained.42 F₁ hybrid individuals of ‘Atlantic’בLongshu No.6’,and 9 F₁ hybrid individuals of ‘Atlantic’בLongshu No.7’ were used for analysis with SSR molecular markers.Two pairs of SSR primers were selected from 59 pairs of SSR primers,and were used for marker analysis among those hybrids and their parents.The results showed that there were 4 types of banding patterns observed in the hybrids,complementary pattern of both parents,deletion pattern,malespecific pattern and femalespecific pattern.Fifty one individuals of F₁ hybrids were identified as true hybrids with primers S184 and STM1049,which showed that it was feasible to identify hybrid potatoes with SSR molecular markers.This research may provide the theoretical basis for further selection of excellent lines with objective traits from potato hybrid descendants.
