Resistance to pod shatter was studied within and between populations of the resynthesized Brassica napus line DK142, grown under glass or in the field, at sites in the UK and Belgium. All populations showed similar ranges of resistance that were greater than that of a commercial cultivar (Apex). The increase in range was at least three-fold greater than the range found in Apex. Only sowing time affected the descriptive statistics of shatter resistance of each line, with spring-sown populations more shatter susceptible than winter-sown populations. The partitioning of dry matter to individual tissues of the pod was different for the two lines, with dry matter biased to the seed in Apex and to the receptacle in the more resistant DK142. In DK142 and Apex, as well as F1 and F2 populations derived from crosses between DK142×Apex, correlations for pod shatter resistance and mature pod characters were high, particularly the weight and length of the valves and septum. Shatter resistance increased in plants when pod numbers were reduced by the removal of whole racemes.

Dominant resistance genes identified in Brassica napus lines are effective against some, but not all, Turnip mosaic virus<br />(TuMV) isolates. An infectious clone of an isolate (UK 1) was used as the basis of chimeric virus constructions using<br />resistance-breaking mutants and other isolates to identify the virulence determinants for three dominant resistance genes.<br />For the resistance gene TuRB01, the presence of either of two mutations affecting the cylindrical inclusion (CI) protein<br />converted the avirulent UK 1 to a virulent isolate. Acquisition of such mutations had a slight cost to viral fitness in<br />plants lacking the resistance gene. A similar strategy is being used to identify the virulence determinants for two more<br />resistance genes present in another B. napus line.

SummaryPod shattering of rapeseed (Brassica napus) causes serious yield loss. Genetic resistance to shattering has been introgressed into B. napus from B. juncea. This followed from allosyndetic pairing between chromosomes of B and C genomes in the interspecific F1 hybrid, B. juncea × B. napus (2n = 37, AABC). The reconstituted B. napus plant showed regular meiosis with 19 bivalents and had pollen and seed fertility of 84 and 23% respectively. An approach is suggested for achieving introgression from monogenomic diploids to digenomic allopolyploids that exploits non-homologous recombination.
