摘　　要：烟薯22号具有产量高、淀粉含量高、抗病性强、适应性广的优点。2006～2007年全国北方薯区区域试验结果:鲜薯平均单产33 831.0 kg/hm2,较对照增产16.09%;两年薯干平均产量9 685.5 kg/hm2,较对照增产17.43%,居第一位。2008年通过国家甘薯品种鉴定委员会鉴定。其高产机理在于烟薯22号具有较高的光合面积和略高的净同化率,并且其T/R值进展合理。Yanshu 22 has the advantages of high yield, high starch content, strong disease resistance and wide adaptability. The regional test results from the Northern district in 2006 - 2007 showed that the average fresh root yield was 33 831.0 kg/hm^2 with 16. 09% increase compared with the check; the average yield of dried sweet potato was 9 685.5 kg/hm^2 with 17.43% increase compared with the contrast, and it was the first of all the new varieties. It passed the identification of the National Identification Committee of Sweet Potato in 2008. The mechanisms of high yield of Yanshu 22 were higher photosynthetic area and net photosynthetic rate, the reasonable value of T/R.
