They are of great importance, especially in studies on the induction of muta- tions and also for the production of homozygous plants, they are needed in large numbers. The conventional methods employed by plant breeders for their production are cumbersome, time-consuming, laborious and rather inefficient. Sometimes it may take years to produce a pure line. However, with the introduction of in vitro techniques, especially anther culture for the induction of androgenesis, it has become increasingly evi- dent that these methods considerably accelerate the production of haploids for plant breeding programs. During the last decade, in vitro-produced haploids have been incor- porated into breeding programs of many agricultural crops, and positive results have been obtained especially with rice, wheat, potato, barley, maize, asparagus, sunflower, brassica, tobacco, etc. Among these, rice and wheat are the best examples in which a number of improved varieties have been released. In wheat, the breeding cycle can be shortened by three or four generations when the pollen haploid breeding method is used instead of conventional cross-b | | 出版日期 | Book 1990 | | 關(guān)鍵詞 | Embryo; Helianthus annuus L; ; Hordeum vulgare L; ; Zea mays L; ; arabidopsis thaliana; bean; breeding; cluste | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-61499-6 | | isbn_softcover | 978-3-642-64856-4 | | isbn_ebook | 978-3-642-61499-6Series ISSN 0934-943X Series E-ISSN 2512-3696 | | issn_series | 0934-943X | | copyright | Springer-Verlag Berlin Heidelberg 1990 |
