Abstract: In order to select drought-resistant rice variety suiting to grow in Hebei province, drought resistance of 21 rice stable varieties was studied by change of the agronomic characters of rice varieties cultivated in the paddy and upland field, which was correlative with crop production. The result indicated that the longer growth date, the shorter panicle length, the lower plant height and the lower yielding capacity of rice varieties were found under the dry cultivation relative to paddy cultivation. Principal factor which influenced rice yield under the dry cultivation condition was grain number per panicle. By drought resistance index and comprehensive evaluation of agronomic character, the result showed rice varieties wd1, wd10, wd11 and wd12 were medium varieties, which were suitable for dry cultivation by their stable yield, superior synthesis characters.
