Abstract: The winter (spring) wheat varieties selected in the experimenthave a characteristic of larger sensitivity to vernalizat ion (photoperiod) than to photoperiod (vernalization). The winter wheat from UKhas not only short photoperiod response similar to super strong winterness (SSW) variety, but also a vernalization accumulative quantity (VAQ) similar to winterness (W) variety. VAQ of winter wheat from USA is similar to st rong winterness (SW) variety, but its response to photoperiod is similar to w interness (W) variety. The spring varieties from UK and Australiahave a weak vernalization similar to the spring varieties from southern China. The difference between natural vernalization and photoperiod condition and the development characteristic of the varieties from UK and USA results in the longer grow ing period and late maturing in winter wheat zone of China.
