摘要： Sixty-nine SSR markers were used to analyze the genetic diversity of 102 germplasm resources adapted to different climatic regions of Heilongjiang province. The results indicated that 50 out of 69 have polymorphism. One hundred eighty nine alleles were detected. The average number of alleles per locus was 3.78 with a range from 2 to 9. Genetic diversity index ranged from 0.019 to 0.761, with the mean of 0.355. Polymorphism information content ranged from 0.019 to 0.641, with the mean of 0.318. The expected heterozygosities ranged from 0.055 to 1.492 with an average value of 0.595. UPGMA cluster analysis showed that the 102 rice materials tested could be divided into four groups at a genetic similarity coefficient of 0.698. The 102 rice germplasm resources from different region showed lower genetic diversity. Rice breeders need to introduce innovation of germplasm in the conventional rice breeding program for further increase of rice yield and stress tolerance in Heilongjiang province.
