Genetic Diversity Analysis on SNP of Core Collection of Wild Soybean in Northeastern China
One hundred and ninety-six wild soybean germplasm were selected from core collection of Northeastern China and the NRT2,AspAT2 and CPK13 gene sequences were used for SNP analysis.We detected 94 SNPs and 10 Indel with average proportion of nucleotide transitions and transversions of about 2∶1.There was 39 rare SNPs(＜ 10％),with ratio of approximately 41.5％.The average proportion of polymorphic sites for 196 core collection was 74％,Shannon's index of 0.366 and diversity index was 0.241.With the decline of latitude,average diversity index of populations of different latitudes was increased,reaching peak at 44°N.Changes in diversity index exhibited normal mode curve.It showed that the central diversity of wild soybean in Northeastern China was found at 42°N-45°N.
