Abstract: F2:10 RIL population with 154 lines, crossed by Charleston as female parent and Dongnong 594 as male parent were used. 164 SSR primers were screened with the two parents and amplified on the 154 lines. 12 agronomic traits different between the two parents are investigated, and QTLs of all traits are analyzed with windows QTL Cartographer V2.0. The agronomic traits includes quality traits: content of protein, content of oil, total content of protein and oil; yield traits: pods per plant, seed weight per plant, and seed weight per hundred; and other traits: plant height, maturity period, branches, main stem nodes, average leaf length, average leaf width. The results show that: 68 QTLs are scanned out for the 12 agronomic traits. QTLs of each trait varied from 3 of average leaf width to 11 of seed weight per hundred and plant height, and the average is 5.8. Compared with the QTLs results at home and abroad, more QTL loci are identical, so they can be used for MAS.
