A survey of development and prospects of the utilisation of doubled haploid techniques in rapeseed breeding in the world and in the Czech Republic is presented. The first utilisation of spontaneously occurred haploids from Brassica napus inbreeding programmes is described. The development of techniques of anther and later microspore culture is outlined. Special emphasis is given to the practical use of doubled haploids for the improvement of the effectiveness of breeding new productive cultivars. Some partial results of evaluation of yield parameters and resistance to important diseases in the obtained doubled haploid lines of winter oilseed rape are shown. The literary review and present results indicate, that the doubled haploid technique can be effectively used for the development of homozygous oilseed rape lines as an alternative to conventional methods.

Breeding Lines

Brassica napus (L.), winter oilseed rape (WOSR) or canola, is one of the most important oilseed crop species of the moderate climate zone. Improving the seed quality and yield makes the main target in breeding programs worldwide. In this study, we examined the genotype-by-environment (G×E) interaction with respect to six seed traits among 25 WOSR genotypes. The plant material included the registered canola cultivars, our newly developed mutant breeding lines and the Ogura F1 hybrids and their parental components, in addition to our domestic breeding lines including two semi-resynthesized (semi-RS) lines. The 25 genotypes were examined in field trials at two locations, in three growing seasons. Seed oil and protein content, total glucosinolates (GLS) content in seed meal and C18 unsaturated fatty acid (oleic, linoleic and linolenic) composition in seed oil were examined. The additive main effects and multiplicative interaction (AMMI) analyses revealed significant effects of both, genotype (G) and environment (E) as well as the G×E interaction regarding the analyzed seed traits. In our study, two Ogura F1 hybrids, a CMS line and a new high oleic mutant breeding line revealed high stability and good average values for most of the analyzed seed traits, thus making a valuable source of starting materials for further improvement.

Genotype × environment interactions, cultivar response to environments and cultivar stability for yield of oilseed rape (Brassica napus L.) were studied using five cultivars grown for 3 yr at nine locations in Manitoba. The objectives were: (1) to estimate the components of variance associated with the first- and second-order interactions and to determine their effects on the standard error of a cultivar mean so that optimum test combinations of replications, locations and years for cultivar testing in Manitoba could be determined; (2) to measure cultivar response to varying environments; and (3) to measure cultivar stability. The genotype × year and the genotype × year × location interactions were significant. The genotype × location interaction was not significant, indicating the cultivars tested performed similarly relative to each other across locations over years. Increasing years, locations and replications in that order had the greatest effects on the standard error of a cultivar mean. Calculation of the contribution of each variety to the G × E sums of squares indicated that Westar made the largest contribution and Altex the smallest.Key words: Rape (oilseed), Brassica napus L., stability, cultivar testing
