　　Brassica rapa (ArAr,2n =20) plays an important role in widening germplasm of B.napus (AnAnCnCn,2n =38) and exploiting intersubgenomic heterosis between natural B.napus and new-typed B.napus created by introgressing component of Ar genome from B.rapa.A RIL population of new-typed B.napus,consisting of 138 lines,was developed by successive selfing a F2 plant of backcrossing,(B.napus × B.rapa) × B.rapa.A linkage map was constructed with 410 SSR markers which were grouped into 24 linkage groups (LGs) and 17 of them were identical with the international reference map of B.napus.
