摘　　要：CS豫麦21号(周麦9号)在1988～1993年黄淮流域三年区试和河南省两年生产试验中产量均居首位。地区、省、国家三级6年85点次试验,平均亩产416.2kg,比4个对照种平均增产11.67％。其中,1992年黄淮流域11处试验,平均亩产506.9kg。生产上最高亩产625.5kg。1992年和1993年先后通过河南省和全国农作物品种审定委员会审定命名。其选育特点是:选用4个遗传背景不同且优良性状互补的亲本复合杂交,加大选育群体及重复选择,人工接种病害及肥水反应鉴定,田间选型与室内考拉结合等,使该品种集矮秆、大穗、高产、多抗于一体,具有较好的高产稳产性,至 1995年累计推广面积已超过 2000万亩。适合黄淮流域进一步扩大种植。GS Yumai 21 ranks frist in two years on demonstration tests of Henan province and Yellow Huai river valley experiment in 1988-1993. Its average yield of 85 locations in six years was 416. 2kg per mu and increased by 11. 67% over four check varieties in prefecture,province and state tests. For exampte.the average yield of 11 co-cations in 1992 was 506. 9kg per mu in Yellow -Huai river valley. The highest output was 625. 5kg per mu in production. It was regestered by Henan province and state crop varieties regestation committee in 1992 and 1993 respectively. The characteristics of se-lection include multiple cross of four parents from dissimilar genetic background and complementary characters,extension of selected population,repeated selection artificial inoculation of disease germ, test of fertilization and irrigation,selection of plant type in the field and examination of seed quality in the room et al. The variety with steadily high yield combined short-stem with large spike,high yield and multiple disease-re-sistance. The total planting area of Yumai 21 was over 20 millions mu by 1995 and the variety adapts further planting in Yellow - Hai river valley.
