“8143”是我们用B_(91)-80∥(69-13-3/小偃4号)F_1杂交,于1986年育成的一个耐渍高产小麦新品系。该品系1986～1990年连续四年在本省旱、涝、冻、病,虫、风等多种自然灾害的严重考验下,经全省不同土质、肥力、茬口和密度近百点次区域适应性鉴定、栽培试验和大面积生产示范检验,已逐步明确它在鄂东南黄冈、咸宁地区,武汉市和江汉平原荆州地区,以及鄂北随州市的丰产性、适应性和利用价值,同时也暴露出一些缺点和问题。“8143”近两年在黄冈地区种植表现突出,去年秋播面积1万余亩,今年秋播计划发展到30万亩左右,“8143”是黄冈地区准备取代鄂麦9号,与鄂恩1号搭配种植的定向示范推广新品种。小麦面积在百万亩以上的随州市,1990年秋播小麦品种定向是稳定鄂恩1号,发展8143”。为了充分发挥“8143”的增产优势,做到良种良法相结合,扬长避短,趋利避害,取得更大的经济效益和社会效益,现就其在适应地区的表现及在推广利用中应注意的有关问题谈几点意见,供生产上参考。
“8143” is a new wheat line with high resistance to drought and stress, which was bred in 1986 by B_ (91) -80∥ (69-13-3 / Xiaoyan 4) F_1. The strain was tested for nine consecutive years from 1986 to 1990 under the severe tests of various natural disasters such as drought, flood, freezing, disease, insect pest and wind in the province. Nearly 100 times the regional adaptability of different soil types, fertility, stubble and density Identification, cultivation and large-scale production demonstration tests have been gradually clear it in Huanggang in southeastern Hubei, Xianning, Wuhan and Jianghan Plain Jingzhou area, as well as Suizhou, northern Hubei’s high yield, adaptability and value, but also exposed Some shortcomings and problems. “8143” in the past two years in the Huanggang area planting outstanding performance last autumn, an area of more than 1 acres of autumn planting this year plans to develop to about 30 acres, “8143” is Huanggang region to replace Emei 9, and E 1 No. With the planting of targeted demonstration to promote new varieties. Wheat area of more than one million mu in Suizhou, the 1990 autumn planting of wheat varieties oriented E Er 1, the development of 8143. “In order to give full play to” 8143 "the advantages of production, so good seeds and good law, to avoid weaknesses, profit-seeking Make more economic and social benefits, and talk about their performance in adapting to the region and relevant issues that should be noticed in the promotion and utilization for reference.
