In a recent article entitled, “Identification of genomic regions involved in resistance against Sclerotinia sclerotiorum from wild Brassica oleracea” published on 25th October in Theoretical and Applied Genetics, Jiaqin Mei and ten associates (majority affiliated to College of Agronomy and Biotechnology, Southwest University, China and J. McKay at Colorado State Univ., Fort Collins) described the results of their investigation in which they succeeded to transfer genes for resistance against Sclerotinia sclerotiorum from a wild accessions of Brassica oleracea to rapeseed (Brassica napus). This achievement will prove to be a milestone in the breeding of Sclerotinia resistant rapeseed cultivars. It may be mentioned here that this important oilseed crop suffers severe yield losses by the attack of stem rot disease caused by this pathogen. Based on their study over two years the immunity for leaf resistance was attributed by them to 12 QTLs while for stem six QTLs. The study took into consideration an F2 population derived from the cross, a resistant line of wild B. oleracea, namely, B. incana X a susceptible line B. oleracea var. B. alboglabra. . The investigators identified on chromosome A09 of B. rapa, a 12.8-centiMorgan long genetic region harboring two major QTL for both leaf and stem resistance comprising 30 putative resistance-related genes. When they surveyed the hybrid population they found that there was a reduction of the relative susceptibility by 22.5% in leaves and 15% in the stem.
