Abstract
A SSR-based linkage map of linseed constructed based on 154 individual lines of F (2) mapping population derived from JRF-4 (disease-resistant) and Chambal (disease susceptible) genotypes. QTLs for Alternaria blight and other yield related traits identified. Out of 1720 SSRs, 216 SSRs were found polymorphic among the parents but due to segregation distortion 18 SSRs could not be used for linkage map construction. Total 191 SSRs were used to construct the linkage map and distributed in 15 linkage groups covering genome length of 1802.4 cM. A total of 10 QTLs were identified for 4 phenotypic traits including 4 QTLs for capsules/plant, 2 for capsule weight/plant, 2 for seed weight/plant and 2 for Alternaria blight resistance. This study laid a foundation for further validation and fine mapping with more advance and large set of marker for different QTL identification and marker-assisted selection in linseed.
