Bread wheat (Triticum aestivum L. ) accounts for 80% of the wheat consumption, howe ver, it is attacked by a large number of pests and pathogens; rusts and smuts cause enormous damage to the crop and reduce the yield drastically in some areas. The major breeding objectives for wheat include grain yield, earliness, resistance to lodging and diseases, spikelet fertility, cold tolerance, leaf duration and net assimilation rate, fertilizer utilization, coleoptile length, nutritional value, organoleptic qualities, and the improvement of charac ters such as color and milling yield. The breeding of wheat by traditional methods has been practiced for centuries, however, it has only now come to a stage where these methods are insufficient to make any further breakthrough or to cope with the world‘s demand. Although numerous varieties are released every year around the world, they do not last long, and long-term objectives cannot be realized unless more genetic variability is generated. | | 出版日期 | Book 1990 | | 关键词 | Expression; Mutation; Pathogen; Triticale; Triticum aestivum L; ; Triticum durum Desf; ; biotechnology; breed | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-662-10933-5 | | isbn_softcover | 978-3-642-08081-4 | | isbn_ebook | 978-3-662-10933-5Series ISSN 0934-943X Series E-ISSN 2512-3696 | | issn_series | 0934-943X | | copyright | Springer-Verlag Berlin Heidelberg 1990 |
