该项研究表明,用不同日数春化处理和连续春播的方法,经过3—4代,可将冬小麦改变为遗传上稳定的春小麦。从阿芙乐尔、高加索和五十周年三个冬小麦品种得到大量的春性品系。冬小麦的基因型和春化处理的时间对冬小麦的转化有明显影响。没有从无芒1号冬小麦品种得到春性品系。春性品系只出现在一定日数春化处理的后代中,但和春化处理日数之间没有规律性的联系。冬小麦向春小麦的转化是逐渐进行的,转化第三代是冬小麦向春小麦转化的关键时期。转化春小麦保持了原始冬小麦品种的一些质量性状,农艺性状表现出广泛的变异。改变冬小麦为春小麦可作为其他育种方法之外创造春小麦育种材料和丰富春小麦种质资源的一个新途径。
The study shows that the winter wheat can be changed to the genetically stable spring wheat after 3-4 generations through the vernalization and continuous spring sowing of different days. A large number of spring lines have been obtained from the three winter wheat varieties of Afre, the Caucasus and the fiftieth anniversary. The winter wheat genotype and vernalization time had a significant effect on the transformation of winter wheat. Spring varieties were not obtained from Wanyang No.1 winter wheat varieties. Spring only appeared in the spring rations of the descendants of a certain number of days, but there was no regular relationship between the vernalization days. The conversion of winter wheat to spring wheat is gradual, and the third generation of transformation is a crucial period for the conversion of winter wheat to spring wheat. Transformed spring wheat maintained some of the quality traits of the original winter wheat varieties, and agronomic traits exhibited a wide range of variations. Changing winter wheat to spring wheat can be used as a new way to create spring wheat breeding material and enrich spring wheat germplasm resources besides other breeding methods.
