Tetraploid citrus progenies arising from FDR and SDR unreduced pollen in 4x X 2x hybridizations
Polyploid citrus arise by somatic and sexual polyploidization, and both have been used in triploid breeding programs. Sexual polyploidization is mainly achieved by first-division restitution (FDR) or second-di...

Recovery of citrus cybrid plants with diverse mitochondrial and chloroplastic genome combinations by protoplast fusion followed by in vitro shoot, root, or embryo micrografting
Somatic embryogenesis and plant regeneration are basic processes for the success of citrus somatic hybridization via protoplast fusion. In many cases, few embryos develop normally and only a small number of pl...

Inheritance in doubled-diploid clementine and comparative study with SDR unreduced gametes of diploid clementine
Tetraploid clementine displays mainly tetrasomic inheritance. Genetic structures of 2n SDR and 2 × gametes from DD clementine are complementary and will guides triploids citrus breedin...

Implementation of extensive citrus triploid breeding programs based on 4x × 2x sexual hybridisations
Seedlessness is one of the most important characteristics for mandarins for the fresh-fruit market, and mandarin triploid hybrids have this trait. Triploid citrus plants can be recovered by 4x × 2x hybridisati...

Extensive citrus triploid hybrid production by 2x × 4x sexual hybridizations and parent-effect on the length of the juvenile phase
The citrus fresh market demands the production of seedless citrus fruits, as seedy fruits are not accepted by consumers. The recovery of triploid plants has proven to be the most promising approach to achieve ...

Multilocus half-tetrad analysis and centromere map** in citrus: evidence of SDR mechanism for 2n megagametophyte production and partial chiasma interference in mandarin cv ‘Fortune’
The genetic structure of 2n gametes and, particularly, the parental heterozygosity restitution at each locus depends on the meiotic process by which they originated, with first-division restitution and second-div...

Recovery of citrus triploid hybrids by embryo rescue and flow cytometry from 2x × 2x sexual hybridisation and its application to extensive breeding programs
Seedlessness is one of the most important characteristics for mandarins for the fresh-fruit market and mandarin triploid hybrids have this trait. Citrus triploid plants can be recovered by 2x × 2x sexual hybri...
