    摘要:

    以15个玉米品种为试验材料,在吉林省半干旱区开展抗旱丰产玉米品种的综合评价及筛选。试验运用玉米产量抗旱指数为主要筛选指标,结合雌雄开花间隔天数(ASI)、植株生长性状、果穗性状和产量性状指标,对参试玉米品种进行综合评价。结果显示,强抗旱品种郑单1002和吉单50,中等抗旱品种先玉335、农华101、中种8号和登海605,干旱胁迫的产量较高,并且ASI等指标好于其他玉米品种,较适合在半干旱区种植。

    Abstract:

    In this article, 15 maize varieties grown in the semiarid area of Jilin Province were comprehensively evaluated and screened for high yield maize varieties with drought resistance. Using corn yield drought tolerance index as the main screening indicators, integrated ASI, plant growth, ear characters and grain yield traits, maize varieties tested were comprehensively evaluated. Results showed that strong drought resistant varieties‘Zhengdan 1002’,‘Ji-dan 50’and medium drought resistant varieties‘Xianyu 335’,‘Nonghua 101’,‘Zhongzhong 8’and‘Denghai605’had high yield under drought stress, and their ASI and other indicators were also better than other maize varieties, so they were suitable for cultivation in semi-arid region.
