Advantages of haploid breeding

Controlling the separation of hybrid progeny, shortening the breeding period, improving the efficiency of obtaining pure material, eliminating recessive interference, and improving the accuracy of selection, etc.

1, controlling the separation of hybrid progeny.

1, control of hybrid progeny segregation, shorten the breeding years: through the haploid induction of haploid plants can appear after chromosome doubling of pure line plants (2n), from which the selection of the excellent pure line progeny are not separated, plant phenotypes neat and consistent, can significantly shorten the breeding years.

2, improve the efficiency of obtaining pure material: haploid plants by chromosome doubling, in a generation can appear pure diploid, from which the excellent pure line offspring are not separated, the performance of neat and consistent, improve the efficiency of obtaining pure material.

3, to exclude the dominant and recessive interference, improve the accuracy of selection: haploid plants by chromosome doubling, can exclude the dominant and recessive interference, improve the accuracy of selection.
