Abstract

An interspecific BC3F2 population (Milyang 23/O. glaberrima/3*Milyang 23) consisting of 141 lines was evaluated for8 traits associated with yield. Oryza glaberrima (IRGC #103544) was phenotypically inferior to all of the traits examined in thisicle and grain yield. A genetic linkage map generated for this population consisted of 124 SSR markers with an average intervallength of 13.1 cM. The percentage of O. glaberrima genome, which was calculated on the number of the exotic gene introgres-sions contained in the 141 BC3F2 lines, ranged from 3.9 to 25.4% with a mean of 12.8%. Of the 37 QTLs associated with yield andyield components, 24 alleles from O. glaberrima were favorable. However, eight QTLs were significantly associated with yieldand five alleles of O. glaberrimafrom 1.5 to 2.2 tons/ha. Exploitation of the genetic potential of exotic species using molecular markers might provide a new oppor-tunity to improve yield and quantitative traits in rice breeding program.
