摘要: 试验应用常规组织分离法分离病原菌串珠镰刀菌。在自然环境下田间播种所测玉米品种(系),花丝萎蔫时采用双牙签法进行病原菌接种。玉米成熟后调查发病情况,依照抗性评价标准确定抗性。结果表明:有1个品种抗性表现为高抗,占鉴定总数的1.8%;有40个品种抗性表现为抗,占鉴定总数的72.7%;有13个品种抗性表现为感,占鉴定总数的23.7%;有1个品种抗性表现为高感,占鉴定总数的1.8%。试验筛选出41个玉米品种(系)可作为山西省玉米抗穗腐病育种利用的种质资源,也为山西省玉米生产选种提供了科学依据。

Abstract: The pathogen fusarium moniliforme was Isolated with conventional tissue separation method.Maize was bred under natural environment.Inoculation was done using the method of double toothpick when the flowers were wilting.Investigation of morbidity was done after the maize were ripe and determining the resistance according to the evaluation standard of resistance. The results showed there was one variety that shows high resistance and account for 1.8% of total materials;there were 40 varieties that show resistance and account for 72.7% of total materials;there were 13 varieties that show sensibility and account for 23.7% of total materials;there was one variety that shows high sensibility and account for 1.8% of total materials. The experiment screen out 41 varieties that can be used as the resources against Ear and Kernal Rot of maize.It also provides the scientific basis for the selecting varieties of maize production in Shanxi province.
