选育与推广晚播早熟、产量高而稳定的小麦品种,是夺取全年粮食均衡增产的重要措施之一,对沿河湾地及低洼易涝的地区更有重要意义.我省淮北地区小麦面积2000万亩左右,占全省麦田面积的三分之二,其中晚茬麦面积约占20%,即达400万亩左右,如遇旱涝灾害天气,晚麦面积更大.长期以来,晚麦产量低,收获迟,也不利于后茬及时整地播种,影响全年均衡增产.为适应生产上的需要,1981年我们从郑州741与杨麦2号的杂交后代中选育出宿育1号小麦新品种,在主要性状上
Breeding and promoting early maturity of late sowing, high yield and stability of wheat varieties is one of the important measures to seize the balanced grain yield throughout the year, is more important for the coastal areas along the Bay and low-lying areas prone to waterlogging. Area of about 2000 acres, accounting for two-thirds of the province’s wheat field area, of which about 20% of the late wheat crop, which amounts to about 400 acres, in case of droughts and floods, late wheat larger area.For a long time, Late wheat yield is low, late harvest, is not conducive to timely seeding crop planting, affecting a balanced increase throughout the year.In order to meet the needs of production, in 1981 we from Zhengzhou 741 and Yangmai 2 hybrid offspring breeding No. 1 new wheat varieties, the main traits
