Seedless fruits are desirable in the citrus fresh fruit *** production via diploid x tetraploid interploidy crosses is thought to be the most efficient and widely-used strategy for the breeding of seedless ***'Orah'mandarin has desirable organoleptic qualities,seeds in the fruits weaken its market *** produce new seedless cultivars that are similar to'Orah'mandarin,we performed three 2x x 4x crosses using'Orah'mandarin as the seed parent to regenerate triploid plantlets.A total of 182 triploid and 36 tetraploid plantlets were *** analyzing their genetic origins using nine novel single nucleotide polymorphism(snp)markers,all of the triploids and tetraploids derived from these three crosses were proven to be ***,we demonstrated that 2n megagametophyte formation in'Orah'mandarin result in tetraploid production in these three interploidy *** tetraploid plantlets were genotyped using eight pericentromeric snp markers and nine centromere distal snp *** on the genotypes of the 2n megagametophytes,the parental heterozygosity rates in 16 snp loci and all 2n megagametophytes were less than 50%,indicating that second division restitution was the mechanism underlying 2n megagametophyte formation at both the population and individual *** triploid hybrids enrich the germplasm available for seedless ***,the tetraploid hybrids are valuable as parents for ploidy breeding for the production of seedless citrus fruits.
