Název v původním jazyce

Chromosome doubling effects of selected antimitotic agents in Brassica napus microspore culture

Popis výsledku v původním jazyce

Effects of microspore culture treatment with antimitotic agents colchicine, trifluralin and oryzalin on the frequency of embryo formation, embryo development, plant regeneration and diploidization rate of winter rapeseed cultivars were compared. In vitroapplications of all antimitotic drugs increased the rate of doubled haploid (DH) plants significantly. Although there were no significant differences in diploidization efficiency between the in vitro applications of particular antimitotic agents, trifluralin showed to be the most suitable because of its positive effect on embryo development and conversion into whole plants. In addition, the diploidization rate was sufficient and stable in all genotypes tested. The results indicate that the trifluralintreatment of microspore cultures could provide efficient chromosome doubling for the production of doubled haploid lines from winter oilseed rape breeding materials.
