小麦育种总的趋势是利用有关学科的基础理论和技术发展,提高单位面积产量,高产更高产;矮秆,耐肥水,抗倒伏;适于密植;提高品质和综合抗病虫害能力等,使产量稳定。一、小麦在我国农业生产和人民生活中的重要作用过去,小麦被视为低产作物,建国初期亩产平均不到100斤。除了栽培技术的原因以外,品种落后,给人们形成“低产”作物的概念。二十多年来,在各种作物中,小麦产量增长幅度最快,它占有粮田总面积的五分之一,占粮食总产量的七分之一,连续获得十四年的丰收。小麦产量平均每年几十亿、
The general trend of wheat breeding is to make use of the basic theory and technological development of the relevant disciplines to improve the yield per unit area and yield higher yield; dwarf, fertilizer-resistant and lodging resistant; suitable for close planting; improve quality and comprehensive pest and disease resistance capacity to stabilize output . First, the important role of wheat in agricultural production and people’s livelihood In the past, wheat was considered a low-yield crop, and the average yield per mu was less than 100 kilograms during the founding of New China. In addition to the reasons for cultivation techniques, the variety is backward, giving people the concept of “low yield” crops. For more than two decades, wheat has been the fastest-growing crop among crops, accounting for one-fifth of the total area of the grain crop, accounting for one-seventh of the total grain output and achieving a continuous fourteen-year harvest. Wheat yields an average of several billion a year,
