WebThe production of doubled haploids (DH) has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species. However, the development of new, more efficient and cheaper large scale production protocols has meant that doubled haploids are also recently being applied in less advanced breeding ... WebThe doubled haploid technique is a method of varietal selection that consists in collecting haploid cells from these gametes in order to provoke a doubling of their chromosome store and obtain a stable line within only two generations. With traditional methods, it takes 6 to 8 generations of self-fertilization and more than 10 years to obtain a ...
