摘要

Drought stress adversely affects plant growth and causes extensive losses in agricultural production. The inheritance of traits is important for developing effective breeding program and the most cost-effective and environmentally friendly approach to improve drought tolerance is deployment of effective resistant genes in cultivars. F1 cultivars allow plant breeders to combine the best traits and multiple host plant resistance. If the parents are homozygous, the hybrids will be uniform, an increasingly important trait in production. However, producing homozygous pure parents takes a long time, a lot of effort and cost. The haploid form is providing a good basis for producing a pure line of plants (DH-doubled haploids) allowing new varieties to be regenerated. The aim of this review is to provide an overview of DH production and different potential methods for haploid induction and their potential effect in the development of drought tolerant germplasm.
