    摘要:

    为了筛选出适宜不同生态类型区土壤种植的抗旱丰产型玉米品种,采用16个常规玉米杂交种,在公主岭可移动防雨棚内用淡黑钙土和黑土进行水分胁迫试验。试验结果表明,玉米株高、穗长、穗粒数和百粒重与玉米抗旱性显著正相关,可作为抗旱性鉴定指标。对4个抗旱性鉴定指标和7个抗旱指标进行抗旱隶属系数分析,评价出适宜半干旱区淡黑钙土种植的高抗旱丰产型品种为先玉335、京科968和华农887,中抗高产品种为秋乐126、吉单50和翔玉218;适宜半湿润区黑土种植的高抗旱丰产玉米品种为先玉335和翔玉218,中抗高产品种为华农887、京科968和吉单50;适用于两种土壤种植的抗旱丰产型玉米品种有先玉335、京科968、华农887、翔玉218和吉单50。

    Abstract:

    In order to screen out drought resistant and high-yield maize varieties which is suitable for planting in different ecological types of soil, 16 conventional maize hybrids were used to carry out water stress test with light chernozem and black soil in movable rainproof shed in Gongzhuling. The results showed that plant height, ear length,kernels per spike and hundred-grain weight were positively correlated with drought resistance of maize, which could be used as drought resistance identification index. Four drought resistance identification indexes and seven drought resistance indexes were analyzed. The results showed that Xianyu 335, Jingke 968 and Huanong 887 were the high drought resistant and high-yield maize varieties. Qiule 126, Jidan 50 and Xiangyu 218 were middle resistant and high-yield varieties. Xianyu 335 and Xiangyu 218 were the high drought resistant and high yield maize varieties suitable for planting in semi humid black soil. Huanong 887, Jingke 968 and Jidan 50 were middle resistant and high yield varieties. The drought resistant and high yield maize varieties suitable for planting in both kinds of soil are Xianyu 335, Jingke 968, Huanong 887, Xiangyu 218 and Jidan 50.
