-i-HAPLOID AND DOUBLED HAPLOID ANGIOSPERMSAbstractHaploids are produced by treating a plant with anapomixic agent at a time of from about flower initiationto about anthesis and collecting the viable apomixic seedproduced. Doubled haploids are obtained by growing theapomixic seed into mature, seed producing plants. Theapomixic technique has many uses, including the fixing ofa plant line into homozygous plant lines.
