WebDoubled haploid technology is a feasible, fast, and cost-efficient way of producing completely homozygous lines in maize. Many factors contribute to the success of this system including the haploid induction rate (HIR) of … A doubled haploid (DH) is a genotype formed when haploid cells undergo chromosome doubling. Artificial production of doubled haploids is important in plant breeding. Haploid cells are produced from pollen or egg cells or from other cells of the gametophyte, then by induced or spontaneous … See more The first report of the haploid plant was published by Blakeslee et al. (1922) in Datura stramonium. Subsequently, haploids were reported in many other species. Guha and Maheshwari (1964) developed an See more Mapping quantitative trait loci Most of the economic traits are controlled by genes with small but cumulative effects. Although the … See more The main disadvantage with the DH population is that selection cannot be imposed on the population. But in conventional … See more Technological advances have now provided DH protocols for most plant genera. The number of species amenable to doubled haploidy … See more Doubled haploids can be produced in vivo or in vitro. Haploid embryos are produced in vivo by parthenogenesis, pseudogamy, or chromosome … See more In DH method only two types of genotypes occur for a pair of alleles, A and a, with the frequency of ½ AA and ½ aa, while in diploid method three genotypes occur with the frequency of ¼ … See more The ability to produce homozygous lines after a single round recombination saves a lot of time for the plant breeders. Studies conclude that random DH’s are comparable to the selected lines in pedigree inbreeding. The other advantages include … See more

Web2. Production of haploids and doubled haploids Haploids produced from diploid species (2n= 2x), known as monoploids, contain only one set of chromosomes in the sporophytic phase (2n=x). They are smaller and exhibit a lower plant vigor compared to donor plants and are sterile due to the inability of their chromosomes to pair during meiosis. WebThe most efficient way to produce doubled haploids in corn is through haploid induction, he adds. “It can be done cheaply in the field and is broadly applicable across all genetic starting material.” Haploid induction … broiling lobster tail in shell
