Abstract:
Abstract: In this paper a four-way recombinant inbred lines population with 160 individuals were used to map QTLs underlying the maturity period- 188 SSR primers were used to identify the genotype of the individuals. The maturity period was recorded in the 4 planting environments trails.Single marker analysis method was utilized to analyze the genotypic data and phenotypic data. The result showed that 14 QTLs conditioning maturity period were mapped to located in 11 linkage groups, i.e, A2, B2, C1, C2, D1b, E, F, G, K, L and N, and the heritability varied from 1.34% to 9.19%.The excellent allelic genotype that could delay the maturity include BARCSOYSSR_08_0966（Q3Q3）, Sat_177（Q2Q2）, Sct_186（Q3Q3）, Satt307（Q3Q3）, Satt557（Q1Q1）, Satt577（Q2Q2）, Sat_351（Q1Q1）, Satt268（Q1Q1）, Sct_199（Q1Q1）, Satt273（Q3Q3）, Satt229（Q1Q1）, Satt664（Q1Q1）, Satt125（Q4Q4）, and those that could shorten the maturity include BARCSOYSSR_08_0966（Q2Q2）, Sat_177（Q1Q1）, Sct_186（Q1Q1）, Satt307（Q2Q2）, Satt557（Q2Q2）, Satt577（Q4Q4）, Sat_351（Q2Q2）, Satt268（Q3Q3）, Sct_199（Q3Q3）, Satt273（Q2Q2）, Satt229（Q3Q3）, Satt664（Q3Q3）, Satt125（Q3Q3）. Among three QTLs i.e, Satt307, Satt199 and Satt125, which were detected in two environments simultaneously, Satt199 showed little variation in effects of allelic genotypes and heritability across two environments, which showed Satt199 could be used in molecular design breeding.
