Association search of molecular markers with determinant of blossom-time in natural and artificial population of Brassica rapa L.

The authors studied thc chromosomal loci, associated with blossom-time, in two-parental splitting population of double haploid and in pivotal collection of native and breeding varieties-populations of B. rapa, using the different types of molecular markers. Utilizing the techniques of QTL-analysis and association mapping the authors identified and mapped the chromosomal loci, situated in linkage group 2, 3,5,6, 7 and 10, and established the AFLP-, SSR- and S-SAP-markers, linked with blossom-time.
