| Abstract: |
| According to the results of experiment conducted on both dry-land and irrigated land in Xiji County from 2003 to 2005 the improved rust-resistant varieties of spring and winter wheat was decided．It was discovered that：Among the winter wheat varieties Jindong 9717 Jindong 941 and Jindong 9718 were ideal on irrigated land in integrated characters and rust—resistance and 8802 Longyuan 935 and Longyuan 992 were ideal on dry-land；Among the spring wheat varieties Ninchun4 802—15 and Dingfeng 806 were suitable on irrigated land and 93—163—6 and Longchun 8139—2 were suitable on dryland．The yield of rust-resistant varieties was15．4％～61．12％ higher than rust-sensitive varieties．When extending the rust-resistant varieties on large scale it is necessary to pay attentions to forecast and control of stripe rust in Ningchun 4 on irrigated lands． |
