玉米种质对黄曲霉菌抗性的鉴定

以145个玉米自交系作为试验材料,对其籽粒人工接种黄曲霉菌(Aspergillus flavus),根据籽粒的发病情况进行抗性鉴定。结果表明:(1)各玉米自交系对黄曲霉菌的抗性有极显著的差异,在145个自交系中,高抗的8份,中抗的72份,中感的57份,高感的8份;(2)对黄曲霉菌有较高抗性的自交系大多数来自于我国的南方地区;(3)通过辐射处理,对于提高抗性可能有较好的效果;(4)爆裂玉米具有较好的抗性;(5)不同致病菌株接种,抗性反应有差异。

Identification of maize germplasm resistant to Aspergillus flavus

The resistance of 145 maize inbred lines to Aspergillus flavus were identified.The results showed that:(1) There were significant difference in resistance among inbred lines.Eight inbred lines were highly resistant,and 72 inbred lines were moderately resistant;(2) Most inbred lines with high resistance to Aspergilluv flavus came from Southern China;(3) Treatment with radiation can increase resistant level;(4) Popcorn were resistant to the disease;(5) There were difference in resistance by inoculation with different strains of Aspergillus flavus.
