Abstract
Yield results showed that ZHONGZUO 966 ranked first, it had an average yield of 3 702kg/hm 2, 9.9% higher than ZAOSHU 18, the control; TAI 96-38 ranked second with the average yield of 3 427 kg/hm 2, 1.7% higher than CK. However, the first three varieties matured later than CK, their growth period were over 100d. The three varieties could be planted as summer sowing varieties in the area with long frost-freeing period such as Linfen and Yuncheng, but not in Taiyuan.
