摘　　要：豫麦１６的选育特点是：采用多抗源异地材料作条本，扩大Ｆ２种植群体规模，Ｆ４选择特优系并配合抗条锈病、白粉病鉴定，Ｆ５进行多点产量试验。通过边试验、边繁殖、边提纯的方法，结合高产栽培试验和组织大面积高产示范，加快了育种进程与推广。初步明确了豫麦１６具有每公顷７５００～９０００ｋｇ的高产潜力。探讨了进一步选育高产品种的育种目标。The breeding characteristics of Yumai 16 were:using multiple disease-resistant germpiasms from different regions,increasing F2 population,selecting the elite families and identifving for stripe rust and powdery mildew resistances in F4,assessing the yield potential of F limes on multiple sites,speeding up the breeding process and utilization of the new variety by the technique of combining experiment with multiplication, selection,cultivation and demonstration at the same time, The results showed that Yumai 16 had a high yield potential of 500-600kg per mu.The breeding obiectives for higher yielding varieties were discussed.
