摘要
2008—2011年,在田间自然条件下系统调查比较了27个鲜食玉米自交系对玉米小斑病、茎腐病和纹枯病3种主要病害的抗病性,同时分析了不同杂交组合的产量差异。结果表明,不同鲜食玉米自交系间抗病性存在差异,其中甜玉米自交系HJT1211、糯玉米自交系YZ22、WN48、FN7和30m抗病性最强,均兼抗玉米小斑病、茎腐病和纹枯病;在14个杂交组合中,有4个高抗兼抗3种玉米病害;不同杂交组合产量差异显著,其中以甜玉米组合"Z132-2×HJT1211"产量最高。
2008-2011, investigation was conducted to study on resistance of 27 fresh corn inbred lines to southern leaf blight of corn, corn stalk rot and sheath blight under field condition. Meanwhile, yield of different hybrid combinations was analyzed. Results indicated that there was significant difference for resistance between inbred lines. Two sweet corn inbred lines （HJT1211） and three waxy corn inbred lines （YZ22, WN48, FN7, 30m） showed the strongest resistance, which were resistant to the three diseases. It also found that four of fourteen hybrid combinations were resistant to southern leaf blight of corn, corn stalk rot and sheath blight. In addition, yield was significantly different between different hybrid combinations, with that of sweet corn combination ＂Z132-2×HJT1211 ＂was the highest.
