摘要
2003～2006年在田间采用人工接种的方法,对我国153份玉米自交系及24份玉米群体材料进行了抗丝黑穗病的鉴定评价。结果表明,对玉米丝黑穗病表现高抗的自交系有P138、4F1、200B、鲁原92、齐319、吉412、合344、东91、CD13和吉495共10份,大多数玉米自交系对玉米丝黑穗病表现感病和高感。加强玉米种质资源的收集、鉴定与评价对玉米抗病育种非常重要。
Taking the method of artificial inoculation under field conditions, the resistance of 153 maize inbred lines and 24 maize populations to Sporisorium holci-sorghi were assessed and evaluated in 2003 - 2006, the results showed that 10 maize inbred lines were high-resistance to Sporisorium holci-sorghi, such as P138, 4F1,200B, Luyuan92, Qi319, Ji412, He344, Dong91, CD13, Ji495. Most of maize inbred lines were susceptible and high-susceptible. It＇s very necessary for resistance breeding to enhance the collection and evaluation of maize germplasm to Sporisorium holci-sorghi.
