Technical development and evaluation of doubled haploid breeding scheme in wheat improvement



Field performance of wheat lines selected by the doubled haploid (DH) and pedigree selection (PS) methods from three F1 crosses were compared with the aim of evaluating doubled haploid method in wheat breeding programs. It took only two years from planting of wheat materials for DH production to planting of selected DH lines for yield evaluation. There was no significant difference in grain yield between DH lines and PS lines selected from an F1 cross whose parental varieties were closely related in their pedigrees. In two crosses with low coefficients of parentage and large variation in their progenies, grain yield of selected DH lines was significantly lower than those of selected PS lines. These results confirm that the DH method has the advantages of saving time in obtaining recombinant inbred lines ready for yield evaluation and of increasing selection efficiency. However, a larger DH population is required to achieve the same level of genetic advance with the PS method in crosses containing greater genetic variation. The application of doubled haploid breeding scheme with selected breeding objectives can thus complement conventional breeding programs and accelerate the release of new varieties in developed countries, as well as in developing countries where rapid varietal development is critical for sustainable wheat production systems.
