AbstractOilseed rape is a very undeveloped crop with regard to efficiency of production and the agronomic practice used to maximize its potential. The genetic potential to modify oilseed rape is limited by the narrow genetic base found within the breeding gene pool, resulting in limited novel variation available for exploitation. Novel variation is, however, present in wild diploid ancestors of oilseed rape and has been made available by developing synthetic Brassica napus. This is illustrated through the use of this material to develop an understanding of pod shattering which is one of the most agronomically important characteristics of the crop. Through a variety of approaches it is shown how progress has been made to understand this trait and how this understanding is being used to improve the crop such that efficiency of production will be enhanced.

Broadening the genetic base of the C genome of Brassica napus canola is needed for continued improvement of this crop. For this, we developed few hundred canola lines from B. napus × B. oleracea interspecific crosses involving a B. napus canola line and six B. oleracea accessions belonging to four varieties, viz. vars. alboglabra, botrytis, capitata and italica, and following two breeding methods (F2- and BC1 (F1 × B. napus)-derived lines). The objective of this study was to understand the genetic structure of this population regarding the alleles introgressed from B. oleracea by using SSR markers, and to investigate the inheritance of B. oleracea alleles in these re-constituted canola lines. Marker analysis showed that the four B. oleracea varieties were genetically quite distinct. Several canola lines derived from these six crosses tended to group together with their B. oleracea parent demonstrating that the wide diversity of the B. oleracea gene pool can be exploited for broadening the genetic base of the C genome of B. napus canola. Loss of several B. oleracea alleles occurred during the development of these inbred lines. While comparing the two breeding methods for introgression of B. oleracea alleles, significantly greater loss of alleles occurred in the F2-derived population as compared to the BC1-derived population. Thus, the knowledge from this study can be used for efficient introgression of exotic alleles from B. oleracea into B. napus for broadening the genetic base of this crop.
