| 中文摘要: |
| 为给我国冬小麦的冬、春性遗传改良提供参考，结合 “济麦”系列小麦品种（济南17、济麦19、济麦20、济麦21、济麦22）及1996年以来年推广面积最大的冬小麦品种的特性及作者多年育种经验，分析了目前小麦冬春性的分类、鉴定方法（常规田间鉴定方法及分子标记鉴定法）及与抗寒性、广适性的关系。小麦冬春性鉴定应将2种方法有机结合，冬春性与抗寒性无必然联系。冬小麦在其他特性相当的情况下，抗寒性强的偏春性品种往往表现出广泛的适应性，冬春麦杂交可作为提高小麦品种广适性的一条重要途径。 |
| 英文摘要: |
| In this paper, combined with characteristics of “Jimai” wheat varieties(Jinan 17, Jimai 19, Jimai 20, Jimai 21, Jimai 22), winter-spring characteristics of widely used wheat varieties in China since 1996 and our breeding experience, the relations between winter-spring type with cold resistance and adaptability analyzed. There were two kinds of methods used in current classification of winter-spring type of wheat,,the conventional field identification method and molecular marker identification method.The combination of conventional field identification method with molecular marker identification method was recommendated for more accurate identification of winter-spring type of wheat varieties, And there were no certain connections between the winter-spring characteristics and cold resistance of wheat genotypes. Spring wheat cultivars with good cold resistance was of wide adaptability while planted as autumn sowing and with the same conditions. The cross between spring wheat and winter wheat was suggested as an efficient strategy to improve the wide adaptability of wheat varieties in China's winter wheat breeding. |
