Gametes have the unique potential to enter the sporophytic pathway, called androgenesis. The plants produced are usually haploid and recombinant due to the preceding meiosis and they can double their chromosome number to form doubled haploids, which are completely homozygous. Availability of the doubled haploids facilitates mapping the genes of agronomically important traits, shortening the tim...

Doubled-haploid lines (DHs) are normally produced from F1 plants in maize (Zea mays L.). Several studies have found a low frequency of recombinants doubled haploids that could limit the selection response. Hence, an attempt was made to produce F2 generation verify whether one more round meiotic recombination lead increased genetic variability and assess response selection. The two cross-combina...

Isolated microspore culture in vitro (IMC) is an advanced technique for producing doubled haploids. We developed a modified isolation method the Brassicaceae family, which exceeds results obtained by standard method. found that new allows increase percentage of microspores at embryogenic stage development culture. In spring rapeseed ‘Ratnik’ increases from 66.7% to 73%, and European radish ‘RBK...

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 Furtherm...
