为了缩短麦子的育种年限,加快杂交世代的繁殖,我们进行了两年观察试验。在本地条件下,用半冬性与春性品种杂交材料夏播,不但能够抽穗结实,而且成熟早,春性愈强则成熟也愈早,全生育期一般比秋播夏熟的约少一半。如用两个春性强的品种杂交材料夏播,播后46天就抽穗,全生育期81天,比秋播夏熟的缩短131天;用半冬性与春性品种杂交材料夏播,播后65天抽穗,全生育期92天,比秋播夏熟的少119天;用冬性与春性品种杂交材料夏播,播后93天抽穗,全生育期114天,比秋播夏
In order to shorten the breeding time of wheat and speed up the breeding cross generation, we conducted a two-year observation and test. Under local conditions, the semi-winter and spring varieties of hybrid materials, summer sowing, not only able to erect, and mature early, the spring is stronger, the earlier the maturity, the whole growth period is generally less than about half of the summer sowing . For example, two spring hybrid varieties of spring variety are sowed. After 46 days of sowing, the ear is eared. The whole growth period is 81 days, which is 131 days shorter than that of autumn seeding. With the hybrid materials of semi-winter and spring, 65 days after sowing, the whole growing period was 92 days, 119 days less than that of summer sowing. The winter sowing and spring sowing hybrids were sowing, and 93 days after sowing. The whole growing period was 114 days,
