| Abstract: | It is necessary to test and analyse productivity and stability of introduced maize hybrids before they are planted in other ecological background. This paper discusses the productivity and stability of maize hybrids introduced from the north of China. The conclusions are as follows: (1) that Haihe 2, Sidan 68, 3119 and 3303 are significantly superior to Zhongdan 2 as CK; (2) that the productivity of hybrids, Shendan 10 and Yuyu 22, are better than CK, but the stability is not as good as CK. Finaly, the hybrids fitting to planting in different districts are suggested. |
