89份甘肃区试鲜食玉米对丝孢堆黑粉菌的抗性鉴定与评价

Identification and Evaluation of 89 Fresh Corns Resistance to Sporisorium reilianum from Gansu Regional Trial

为明确不同鲜食玉米品种抗丝黑穗病差异,本研究采用田间人工接种法,于2015—2017年在甘肃省天水市甘谷县对89份甘肃省区试鲜食玉米品种进行抗性鉴定。结果表明,在89份鲜食玉米品种中,9份材料‘彩糯1号’、‘甘甜糯1号’、‘秦粮糯902’、‘九洋双色蜜’、‘AP358’、‘酒糯4103’、‘雅玉1号’、‘禾糯1号’和‘田福糯1号’表现高抗(HR);5份材料‘保糯1号’、‘田福糯2号’、‘甘垦糯2号’、‘金辉306’和‘瑞糯260’表现抗(R);9份材料‘华甜玉6号’、‘白玉909’、‘朝糯606’、‘12009’、‘银玉16号’、‘黄糯90’、‘白甜糯828’、‘原玉糯505’和‘仲甜5号’表现中抗(MR);其余36份和30份表现感(S)和高感(HS);高抗、抗、中抗、感、高感分别占供试玉米品种的10.11%、5.62%、10.11%、40.45%和33.71%。

The paper aims to confirm the head smut resistance difference among fresh corn cultivars.We identified the resistance of 89 corn cultivars in Gangu,Tianshui of Gansu by the method of artificial inoculation in field during 2015-2017.The results showed that:among the 89 fresh corn cultivars,9 were highly resistant,including'cainuo1','gantiannuo1','qinliangnuo902','jiuyangshuangsemi','AP358','jiunuo4103','yayu1','henuo1'and'tianfunuo1';5 cultivars were resistant,including'baonuo1','tianfunuo2','gankennuo2','jinhui306'and'ruinuo260';9 cultivars were moderately resistant,including'huatianyu6','baiyu909','zhuonuo606','12009','yinyu16','huangnuo90','baitiannuo828','yuanyunuo505'and'zhongtian5';the other 36 and 30 cultivars were susceptible and highly susceptible;HR,R,MR,S,HS accounted for 10.11%,5.62%,10.11%,40.45%and 33.71%,of the 89 cultivars respectively.
