The purposes of this research project are to identify quantitative trait loci (QTLs) associated with yield-related traits using a recombinant inbred line (RIL) population derived from a cross between a high-yield soybean genotype SS0404-T5-76 and Daewonkong and to develop high-yield soybean and lodging-resistant sprout soybean cultivars. For development of DNA markers and identification of functional sequence variations, firstly, whole genome of five soybean genotypes, Sinpaldalkong 2, SS2-2, Pungsanamulkong, SS0404-T5-76 and Daewongkong, were sequenced using Illumina Hi-Seq technology. SS2-2 is a EMS-induced mutant of Sinpadalkong 2. SS0404-T5-76 showing high-yield is a F8 RIL derived from a cross of Pungsanamulkong x SS2-2. Daewonkong is a elite cultivar with high-protein. Furthermore, to construct a genetic linkage map, we are advancing F4 lines of SS0404-T5-76 x Daewonkong by single seed-descent. Secondly, we developed high-protein and high-yield soybean lines and lodging-resistant sprout lines. Area-adaptability tests of these promising lines are performing in three different locations including Jeju, Naju, and Suwon. Based on the results of area adaptability tests, we are planing to conduct cultivar registration of the promising soybean lines.
