1979～1983年,通过春化室、温室等人工设备和山区、大田等自然条件相结合,异季集团加代和正季单株选择相结合的途径,研究了小麦幼苗春化加代育种技术,技术要点:(1)双氧水低温法打破种子休眠;(2)春化室幼苗春化:处理温度8～10℃,连续光照30天左右;(3)一年三代育种:山区集团密植夏繁,温室集团密植秋繁,就地大田单粒冬播,苗期薄膜棚覆盖,单株选择。实现了不同春化习性全套育种材料为一年三代育种。 From 1979 to 1983, through the combination of artificial equipment such as vernalization house, greenhouse and other natural conditions such as mountainous area and field, the combination of heterosis group plus generation and single plant selection, the spring vernalization and substitution breeding techniques of wheat seedlings were studied. : (1) Hydrogen peroxide hypothermia method to break seed dormancy; (2) vernalization of vernalization room seedlings: treatment temperature 8 ~ 10 ℃, continuous light for about 30 days; (3) Breeding one year three generations: Dense planting autumn and autumn, local single grain winter sowing, seedling film shed cover, single plant selection. Achieve a full set of different breeding habits of breeding materials for three generations of breeding a year.
