贵州小麦科研现状与今后的重点分析

Research Situation and Major Analysis on Wheat in Guizhou

贵州是小麦的适宜区,常年面积在46万hm2左右,虽然近年来有下降的趋势,但仍是夏收的主要粮食作物。贵州小麦在科研取得一定成就的基础上,还存在科研人才后劲不足,科研条件还需改善,科研水平急待提高等现状。为此,提出进一步提高贵州小麦产量,改良和提高小麦品质,促进优质高效小麦栽培技术体系的建设,利用外源基因导入小麦,拓宽小麦的遗传基础,开展杂交小麦研究,加强抗病育种和病害防治等作为今后小麦科研的重点选择内容。

Wheat is the main summer food crop with about 0.46 M ha of planting area annually in Guizhou. Owing to short of talented scientific researchers and essential research conditions, the scientific research level waits for raising, so the yield of wheat is slightly down recently in Guizhou. Some key research measures for wheat including improving its yield and quality, building the high-efficiency cultivation technical system, developing hereditary base by introducting exotic genes, carrying out breeding of hybrid wheat, enhancing breeding for resistance to diseases and controlling diseases should be emphasized to improve total wheat yield in Guizhou.
