利用我国丰富的气象资源宝库,研究小麦及小麦品种对温、光的反应,对提高小麦育种选择效应,改进农艺措施,发展小麦生产,都是有益的。几年来,白城专区农科所试验地对辽、吉、黑三省种植面积较大的辽春6号、丰强2号、新曙光1号、克丰1号以及墨西哥品种他诺瑞、伊尼亚等6个品种进行适应性考察。近年又在南宁进行冬播,乐业进行夏播,白城进行春播试验看出:1.在高温、多照条件下,不同熟期类型品种之间生育日数相差2～3天,最多不过5～7天;而在低温、少照条件下相差6～19天,最多差28天。因此,在短日照下选择早熟亲本,或选早熟株系或个体,可以提高选择效应,因为
Using our abundant treasure house of meteorological resources to study the response of wheat and wheat varieties to temperature and light, it is beneficial to improve the selective effect of wheat breeding, improve agronomic measures and develop wheat production. Over the past few years, Baicheng Prefecture Agricultural Experimental Station on Liao, Kyrgyzstan, Black three provinces planted a larger area of Liaochun 6, Fengqiang 2, New Dawn 1, Kefeng 1, and Mexican varieties of his Nuorui, Asia and other six varieties of adaptability inspection. In recent years, winter sowing in Nanning, music industry for summer sowing, white sowing spring sowing test shows: 1. At high temperature, under multiple conditions, the maturity of different types of maturity days vary between 2 to 3 days, up to but 5 ~ 7 days; while in low temperature, under the conditions of less than 6 to 19 days, up to 28 days difference. Therefore, selecting early-maturing parents or selecting early-maturing lines or individuals under short daylight can improve the selection effect because
