| Abstract: |
| Drought is one of the critical environmental factors affecting wheat yield in Heilonggang area, Hebei Province. It is of great importance, therefore, to identify drought\|resistant accessions from newly released wheat varieties to ensure food security and to save underground water resource used for ecological purpose. The objective of this study was to screen drought\|resistant varieties from 38 wheat varieties recently released in central and southern area of Hebei Province under field conditions treated with different water regimes. The test was carried out under field conditions at experimental stations of Cheng'an and Xinji counties during two growing seasons of 2017-2018 and 2018-2019. The results showed that, could be used to evaluate the drought resistance of wheat varieties under field conditions when drought index (DI) based on yield combined with high stability coefficient (HSC), and a total of six varieties were chosen as varieties with drought resistance and highly yield stability. Also, six varieties were selected as varieties with drought resistance but medium stability. The selection of these drought\|resistant wheat varieties had laid a crucial foundation for achieving water\|saving through biological way in the Heilonggang area. |
