“…Although the impacts of improved phenotypic prediction models (i.e. Genomic Selection) and doubled haploid production have sped breeding cycles for some crops (Morrell et al, 2011;De La Fuente et al, 2013), a number of edaphic stresses (lack of water and low soil fertility chief among them) still provide major uncertainties in crop production from year to year. These factors contribute to negative outcomes in industrialized farm systems, such as pollution of waterways due to inefficient application of fertilizers, strains on fresh water resources, and in the most vulnerable parts of the world can lead to low crop yields and persistent food insecurity (West et al, 2014).…”

“…De La Fuente et al (2013) proposed an in vitro nursery approach to quickly produce homozygous and homogeneous lines by combining an offseason nursery (i.e., increasing generations per year) and DH technology (i.e., instant homozygosity per generation). In their approach, the tissues from selected genotypes are extracted and converted into a tissue culture, and after the somatic cells are stabilized in culture they are induced to undergo meiosis to get gametes that undergo mitotic cycles to get clonal cells.…”

The discovery of haploids in higher plants led to the use of doubled haploid (DH) technology in plant breeding. This article provides the state of the art on DH technology including the induction and identification of haploids, what factors influence haploid induction, molecular basis of microspore embryogenesis, the genetics underpinnings of haploid induction and its use in plant breeding, particularly to fix traits and unlock genetic variation. Both in vitro and in vivo methods have been used to induce haploids that are thereafter chromosome doubled to produce DH. Various heritable factors contribute to the successful induction of haploids, whose genetics is that of a quantitative trait. Genomic regions associated with in vitro and in vivo DH production were noted in various crops with the aid of DNA markers. It seems that F2 plants are the most suitable for the induction of DH lines than F1 plants. Identifying putative haploids is a key issue in haploid breeding. DH technology in Brassicas and cereals, such as barley, maize, rice, rye and wheat, has been improved and used routinely in cultivar development, while in other food staples such as pulses and root crops the technology has not reached to the stage leading to its application in plant breeding. The centromere-mediated haploid induction system has been used in Arabidopsis, but not yet in crops. Most food staples are derived from genomic resources-rich crops, including those with sequenced reference genomes. The integration of genomic resources with DH technology provides new opportunities for the improving selection methods, maximizing selection gains and accelerate cultivar development. Marker-aided breeding and DH technology have been used to improve host plant resistance in barley, rice, and wheat. Multinational seed companies are using DH technology in large-scale production of inbred lines for further development of hybrid cultivars, particularly in maize. The public sector provides support to national programs or small-medium private seed for the exploitation of DH technology in plant breeding.

“…Pre-selection of the best predicted hybrids for detailed field testing is a promising approach to accelerate selection gain, because breeders' resources can be focussed on those materials that are predicted to harbour the highest yield potential. We expect genomic prediction techniques in plant breeding (reviewed in [15,16]) to benefit greatly from large-scale germplasm enrichment into breeding populations using HHC-like approaches. Simultaneously, the availability of immortal heterotic populations and their fully genotyped parental lines, associated with extensive data from fieldbased and controlled-environment phenotyping, provides a powerful resource for genome-scale investigations into the genetic basis of heterosis for yield and other important agronomic traits.…”
