Efficiency of Microspore Culture for Doubled Haploid Production in the Breeding Project ''Czech Winter Rape?. Czech J. Genet. Plant Breed., 42, 58-71, ISSN 1212-1975.

Popis výsledku v původním jazyce

The selected set of twenty inter-line F1 hybrids of Brassica napus L. was evaluated for their capacity to produce microspore-derived doubled haploid (DH) plants subsequently utilized in the breeding ?Czech Winter Rape''. All tested genotypes were able toproduce microspore-derived embryos based on the standardized protocol previously adopted for the Czech winter rape varieties/breeding lines; nevertheless, significant differences were found in the frequency of microspore-derived embryos production as related to particular genotypes. However, the fertile dihaploid DH regenerants were obtained only in 12 hybrid lines of this set. The other 8 lines failed to produce fertile DH plants for several reasons, mainly due to altered morphology of microspore embryos connected with limited germination/conversion potential and due to unsuccessful colchicine treatment resulting in haploid or mixoploid (chimeric) regenerants exhibiting partial or full sterility. In general, colchicine treatment induc
