Intervarietal substitution lines (ISLs) having one or a few defined segments of a donor genome in the common genetic background of a recurrent parent can be used to search the genome for donor alleles affecting traits. A complementary set of substitution lines represents ideally the whole donor genome divided into a limited number of distinct segments, each carried by a different line. ISLs were suggested as an alternative to a segregating population for QTL mapping. An ISL population can be used to overcome the limitations of a segregating population in the accuracy of QTL localization. With overlapping donor segments in different substitution lines and their respective phenotypic values, QTL positions can be narrowed down to a few centimorgan (cM), allowing a high precision of QTL localization.The main objectives of this study were:- To develop set of intervarietal substitution lines (ISL) from the cross of ¿Express` x resynthesized line ¿RS239` - To map QTL for some agronomically important traits in two sets of ISL populations developed from the crosses of ¿Mansholt` x ¿Samourai` and ¿Express` x resynthesized line ¿RS239` - To compare QTL results mapped in the ISL population with QTL mapped in an earlier generation (F1DH population) developed from the cross ¿Mansholt` x ¿Samourai` For this, a set of ISLs was developed from a cross between the spring type resynthesized rapeseed line ¿RS239` and the winter rapeseed variety ¿Express` (¿ExRS239`). A second set, developed from a cross between doubled haploid lines of the two winter rapeseed varieties ¿Mansholt` and ¿Samourai (¿MxS`), was available from earlier work. The ISLs were developed through five backcross generations. Using marker assisted selection with AFLP markers, lines carrying a complementary set of donor segments were selected.
