THE PRODUCTION OF HAPLOID SEED, OF DOUBLED HAPLOIDS AND OF HOMOZYGOUS PLANT LINES THEREFROM

摘要

In a process for producing haploid seed haploids are induced in an angiosperm by applying an apomixic agent to a plant at a time which is between the occurrence of flower initiation and anthesis in an amount sufficient to cause apomixis, allowing the plant to produce seed and collecting from the seed, viable, haploid seed. The process may be used to produce doubled haploids in an angiosperm by further growing the haploid seed in an environment which fosters the development of the embryo into a plant which is capable of producing doubled haploid seed. The process enables homozygous plant lines to be obtained. The process may usefully be applied to cereal grain and forage crop plants.
