| Research Abstract |
A large number of quantitative trait loci (QTLs) controlling economic traits of chickens were discovered, using a resource family derived from Oh-Shamo males and White Leghorn females. The number of QTLs detected is as follows. Growth-related traits : 229 main-effect QTLs and 18 pairs of epistatic-interaction QTLs ; egg-related traits : 67 main-effect QTLs and 16 pairs of epistatic-interaction QTLs ; and meat-related traits : 14 main-effect QTLs. These QTLs will be useful for future DNA-based breeding.
