| 摘 要： | 为提供玉米新品种。保证广西玉米生产可持续发展，进行玉米新组合鉴定试验，以筛选出玉米新组合。试验表明：20个参试品种中，18个组合表现为增产，正大619（CK）在20个组合中产量排名第19位，有S127表现为减产；基中KJ 1242、GD1201、KJ1226产量排名前三名，增产幅度在45％以上，说明在水肥条件较好的地区种植丰产性好；S127、6222、212B-30后期叶片保绿性好，耐熟性强；金卡6号抗病性差。

| Abstract: | In order to provide new maize varieties and ensure the sustainable development of maize production, a qualification experiment of autumn maize new combinations was conducted to screen out new combinations. The results show that among the 20 tested varieties, 18 combinations represent yield-increase and the CK （Zhengda619） ranks only 19th for yield. Moreover, S127 represents yield-decrease, KJ1242, GD1201 and KJ1226 rank top three for yield with yield-increase of over 45%, which means in areas of good water and fertility condition, they will have better yield representation. The green-leave keeping in late period of S127, 6222 and 212B-30 are better with stronger mature-bearing. Jinka 6 has weak disease-resistance. |
