小麦加代繁殖是加速新品种选育进程的主要途径 ,国内外对此已作了大量的研究。日本百足幸一郎利用温室加代 ,实现了对春小麦进行 1a4～ 6代的培育 [1] 。我国普遍采用的是异地加代的方法 ,但由于自然条件的限制一般只能实现冬、春性材料 1a繁育3代 [2～ 5] ;同时 ,在解决夏季低 Addition of wheat is one of the main ways to speed up the selection and breeding process of new varieties. Many researches have been done on it at home and abroad. Japan’s Yukio Shigeyou use of greenhouse plus generation, to achieve spring wheat 1a4 to 6 generations of cultivation [1]. However, due to the restriction of natural conditions, it is generally only possible to achieve the breeding of winter and spring materials 1a by 3 generations [2 ~ 5]. In the meantime,
