豫玉 11号(原名 90—1)是一个坚叶、大穗、高产、优质、多抗、适应性广的玉米杂交种。该杂交种在1990～1991年河南省玉米区试中,平均亩产529.5kg,比对照种增产14.9％,达极显著水平,居首位。该杂交种在1992～1993年全国夏玉米区试中,晋、鲁、豫、皖、苏五省平均亩产512.3kg,比对照掖单2号增产15.7％,亦达极显著水平,居首位。在全国二十多个省(市、区)试验示范中,一般比对照种增产8.7％～47.6％。在河南省夏播示范中,亩产达900.1kg。其群体叶面积变化呈前快、中稳、后慢的理想曲线,植株氮代谢水平高,干物质积累快、总量大,且分配合理,经济系数高,因而增产显著。该杂交种高抗青枯、大小斑等多种病害,较抗倒耐旱,综合性状优良,品质好,中熟,适宜密度范围较大,制种产量高,适合我国大部分省份春、夏、秋播中等以上肥力地种植。
Yu Yu 11 (formerly 90-1) is a corn, big spike, high yield, high quality, multi-resistance, wide adaptability of corn hybrids. The hybrids in the 1990-1991 maize area test in Henan Province, the average per-mu yield of 529.5kg, 14.9% increase over the control species, reaching a significant level, ranking first. The hybrids in the 1992 ~ 1993 National Summer Corn Zone test, Jin, Shandong, Henan, Anhui and the five provinces average yield 512.3kg, compared with the control Yedan 2 15.7% increase, also reached a significant level, ranking first Bit. In more than 20 provinces (cities, districts) pilot demonstration, the general increase of 8.7% to 47.6% over the control. Summer sowing demonstration in Henan Province, the mu yield of 900.1kg. The leaf area change of the population showed the ideal curve of fast, stable, slow afterward. The nitrogen metabolism of plants was high, the accumulation of dry matter was fast, the total amount was large, the distribution was reasonable, and the economic coefficient was high. The hybrids are highly resistant to many diseases such as chlorosis, size spots and the like, are more resistant to drought and drought, have better comprehensive characters, better quality and medium maturity, higher suitable density range and higher seed production yield, and are suitable for spring, summer and autumn in most provinces of our country Planting medium or above fertility.
