扬麦4号小麦系江苏省扬州地区农科所用南大2419×胜利麦5代品系,再与阿夫选系2号杂交育成。我所于1981年引入,经两年试种观察,初步证实该品种具有早熟、高产、抗病等优良性状。1983年小麦生长后期阴雨连绵,锈病流行,赤霉病重发。在这种极为不利的天气条件下,仍表现青秆黄熟,获得较好的收成。我所大田栽培20.01亩,平均亩产573.2斤,比浙麦2号增产13.6%。有五块田计6.47亩,亩产超过700斤,其中最高一块田1.02亩,亩产高达804.9斤。近两年来,台州地区曾对该品种组织考察评选,1982年冬播面积近千亩,普遍反应良好,预计1983年冬播将有较大的面积。
Yangmai 4 wheat is used in Yangzhou, Jiangsu Province, Nanda 2419 × Victory wheat line 5 generations, and then selected with the Ave hybrids bred. I was introduced in 1981, after two years of trial planting observation, initially confirmed that the varieties with early maturity, high yield, disease resistance and other fine traits. In 1983 the late wheat growing rainy, rust epidemic, scab disease recurrence. In this extremely adverse weather conditions, the performance is still stout straw, get a better harvest. My field cultivation of 20.01 acres, an average of 573.2 kg per mu, Zhejiang wheat than 2 increased by 13.6%. There are five fields of 6.47 acres, more than 700 pounds per mu, of which the highest one 1.02 acres of fields, up to 804.9 kg per mu. In the past two years, Taizhou Prefecture once inspected and selected the breed organizations. The area of winter seeding in 1982 was nearly a mu, and generally responded well. It is estimated that there will be a large area for winter seeding in 1983.
