METHOD FOR SELECTING HAPLOID OR DOUBLED HAPLOID PLANTS, HAPLOID-INDUCING PLANTS, AND HAPLOID OR DOUBLED HAPLOID PLANTS OF MATERNAL OR PATERNAL ORIGINE

摘要

The present invention relates to a method for selecting haploid or double haploid plants. According to the invention, a line carrying a haploid-inducing gene and homozygous for a single dominant dominant lethal gene, which can direct the conversion of a non-lethal or non-inhibitory factor into a lethal or inhibitory factor, or a dominant selectable marker gene, is used. can be a toxic, inhibitory or otherwise metabolically disturbing factor to a less toxic, less inhibitory or less metabolically disturbing factor, or to a dominant screenable marker gene whose product can form a phenotypically detectable characteristic in the tissue containing it. The invention also relates to haploid inducing plants and to haploid or double haploid plants of paternal or maternal origin. ŕ
