| Outline of Final Research Achievements |
This research was conducted for getting knowledge about the mode of unreduced pollen formation in ‘Nishiuchi Kontasu’ hyuganatsu. Based on the information of linkage map and DNA markers in clementine mandarin, SNP markers located near the centromere were screened. It was shown that the ratio of the number of alleles up to hexaploid was able to be reflected on the two dimensional plot. SNP genotypings for embryo and tegmen (containing endosperm tissue) from normal seeds obtained by pollination of ‘Nishiuchi Konatsu’ pollen revealed that almost all loci of the unreduced pollen were heterozygous, suggesting that the for unreduced pollen was formed through FDR (First Division Restitution).
