Genes | Free Full-Text | Quantitative Trait Loci (QTLs) Associated with Microspore Culture in Raphanus sativus L. (Radish)

< div class= "art-abstract in-tab hypothesis_container" > The radish is an extremely self-incompatible plant, and consequently it is difficult to produce homozygous lines. Bud pollination in cross-fertilization plants must be done by opening immature pollen and connecting pollen to mature flowers. It accordingly takes a lot of time and effort to establish lines with fixed alleles. In the present research study, a haploid breeding technique has been applied to get homozygous plants in a brief amount of time by doubling chromosomes through the induction of a plant body in the haploid cells, in order to shorten the time to breed inbred lines. We constructed hereditary maps with an F1 population derived by crossing parents that reveal a remarkable and inferior ability to regrow microspores, respectively. Genetic maps were built from the maternal and adult maps, individually, using the two-way pseudo-testcross design. The phenotype of the regeneration rate was taken a look at by microspore cultures and a quantitative quality loci (QTL) analysis was carried out based upon the regeneration rate. From the results of the culture of microspores in the F1 population, majority of the group did not regrow, and just a few showed a high regrowth rate. A total of five substantial QTLs were found in the F1 population, and 5 candidate genes were discovered based upon the results. These prospect genes are divided into 2 classes, and appear to be related to either PRC2 subunits or auxin synthesis.
