| Abstract: | The adaptability of some new maize varieties in the mid-low-yielding fields of Henan province was tested,and these maize varieties were screened according to their yield,agronomic characters and resistibility.The main results were as follows:in comparison with CK variety Zhengdan 958,the yield of Zhengdan 136,Xianyu 335,Zhongke 11 and Xundan 20 was increased by 12.8%,12.5%,5.0% and 4.9% respectively,the yield difference was obvious,and the adaptability,resistibility and agronomic characters of these four varieties were good,so they could be planted in the area,while the others should be observed in further tests. |
