Abstract:
In order to explore the association sites of soybean seed protein content,oil content,and 100-seed weight with SSR markers of local and bred soybean varieties in Sichuan and Chongqing region,232 natural populations composed of local and bred materials in Sichuan and Chongqing were used as experimental materials,and 135 SSR molecular markers distributed on 20 chromosomes of soybean were combined to examine the genotypes of all materials.The mixed linear model in TASSEL3.0 software was used to analyze the correlation between soybean seed protein content,oil content and 100-seed weight.The results showed that a total of 49 association sites were detected in the two environments when P<0.05 was significant and the contribution rate was high.There were 16 loci significantly associated with protein content,the total contribution rate was 29.78%,19 loci related to oil content,the total contribution rate was 41.94%,and 14 loci related to 100-seed weight,the total contribution rate was 13.92%.The loci satt554 and satt229 were simultaneously associated with seed protein content,oil content and 100-seed weight.
