History and Current Status of Haploidization in Carrot (Daucus carota L.)

The induction of haploid cell development into normal plants enables the production doubled lines, which are homozygous and can be used in breeding programs as an alternative to conventionally derived inbred lines. In this paper, we present historical background current status attempts carrot (Daucus carota L.). Economically, is one most important vegetables. It outcrossing diploid (2n = 2x 18) species. Nowadays, seeds hybrid cultivars constitute majority sold world. Hybrid produced using populations. Inbreeding species difficult due inbreeding depression also time-consuming, it a biennial crop. Therefore, implementation haploidization technology high interest. Androgenesis, gynogenesis induced parthenogenesis methods that have been for induction, their potential discussed. centromere-specific histone 3 variant (CENH3) its manipulation acknowledged.
