1998～ 1999年 ,在人工接菌条件下 ,对 6 73份玉米种质资源进行了抗丝黑穗病的抗性鉴定。鉴定结果表现高抗材料 115份 ,占鉴定总数的 17 1% ;抗病 193份 ,占 2 8 7% ;感病 2 2 5份 ,占 33 4% ;高感 14 0份 ,占 2 0 8%。 1998年从鉴定出的高抗、抗病材料中选出 94份 ,第二年进行了重复鉴定。复鉴后的高抗材料 36份 ,占复鉴总数的 38 3% ;抗病 4 7份 ,占 50 0 %。

From 1998 to 1999, 673 maize germplasm resources were tested for resistance to head smut under artificial inoculation conditions. The identification results showed that 115 were high resistant materials, accounting for 17.1% of the total; 193 were resistant to disease, accounting for 28.7%; 224 were susceptible to disease, accounting for 33.4%; and were highly susceptible to 220, accounting for 208 %. In 1998, 94 high-resistant and disease-resistant materials were identified, and the second year was repeated. After the rejuvenation of 36 high-resistant materials, accounting for 38 3% of the total number of complex; disease resistance 4 7, accounting for 50%.
