Quantitative Trait Loci in Brassica rapa,
Pagination or Media Count:
This paper briefly examines current methodology for developing genetic linkage maps and using them to find loci for quantitative traits QTL. Maximum likelihood interval mapping is viewed as an extension of classical least squares methods when the trait of interest is normally distributed and located near a genetic marker. Some problems in finding multiple loci for a quantitative trait are examined for days to budding as measured on F2 plants from a Brassica rapa cross. Relevant design aspects of molecular biology experiments are briefly noted.
