摘　　要：对两年区试结果分析表明，豫玉２２号（豫单８７０３）属高产、稳产型玉米新杂交种，是目前替代丹玉１３的理想品种。由于其含有热带亲本血缘，因此，它的推广应用也有利于改善目前生产上品种单一老化、遗传基础狭窄的状况。The analysis on the data from the region experiments for two years.The result shows that Yu Yu22,a new corn variety with high and stable yield,is an ideal variety to substitute Dan Yu13 at present.As it contains the tropical parental blood,the popularization of Yu Yu22,will be favourable for changing the status of single and ageing varity,and the narrow genetic background in production.
