PRODUCTION MUTANT LINES OF TURNIP RAPE (BRASSICA RAPA) AND ITS INTERSPECIFIC HYBRIDS IN THE ISOLATED MICROSPORE CULTURE

This article presents the results of research on production mutant doubled haploids turnip rape (Brassica rapa L.ssp.Oleifera), as well its interspecies hybrids with rapeseed napus). An  immature embryo culture  was used to increase productivity inter-specific hybridization. Studies have obtained interspecific rapeseed. The largest number plants observed in where mother plant Furthermore, chemical mutagenesis genetic diversity studied materials. Ethyl methanesulfonate (EMS) has been applied treatment embryos produced isolated microspores and hybrids. Results regeneration against mutagen a nutrient medium B5 gibberellic acid showed that concentration 8 mM EMS stimulated process cultivars (Zolotistaya - 72% Yantarnaya 88%) superior compared low (4 mM). For high (8mM), 4mM results. New lines starting material for selection creation new domestic canola cultivars.
