玉米粗缩病是安徽省玉米产区重要病害,选育和应用抗病品种是唯一经济高效的防治措施。于2009年,对安徽省33个玉米品种进行粗缩病田间鉴定。根据相对抗病指数,将品种分为高抗(HR,0~0.20)、抗病(R,0.21~0.39)、中抗(MR,0.40~0.59)、感病(S,0.60~0.79)、高感(HS,0.80~1.00)5类。鉴定结果表明:高感粗缩病的品种有13个(病指在52.1~100),分别是鲁宁202、雅玉12、弘大8号、滑玉13、苏玉20、郑单23、浚单18、中科11、益丰29、郑单958、申源213、蠡玉13和济单8号;感粗缩病的品种有8个(病指在41.0~52.0),分别是隆平206、浚单20、先玉335、金赛29、鲁单661、中农大236、鲁单981和金赛6850;中抗粗缩病的品种有5个(病指在31~40),分别是齐单1号、中农大311、利民15、皖玉17和东单80;抗粗缩病的品种有5个(病指在14.1~30.0),分别是中科4号、宿单9号、蠡玉35、鲁单6018和蠡玉16;高抗粗缩病的品种有2个(病指在0~14.0)分别是登海3号和农大108。
Maize is one of the important diseases in maize producing area in Anhui Province. It is the only economical and effective prevention and control measure to breed and apply disease-resistant varieties. In 2009, 33 maize varieties in Anhui Province were identified for their crude diseases. According to the relative disease resistance index, the cultivars were divided into three groups: high resistance (HR, 0-0.20), disease resistance (R 0.21-0.39), moderate resistance (MR 0.40-0.59), susceptible (S 0.60-0.79) High sense (HS, 0.80 to 1.00) 5 categories. The identification results showed that there were 13 varieties with high susceptibility to the disease (52.1 ~ 100), including Luning 202, Ya Yu 12, Hongda 8, Yuyu 13, Suyu 20, Zhengdan 23, Xundan 18, Zhongke 11, Yifeng 29, Zhengdan 958, Shenyuan 213, Yuyu 13 and Jidan 8; there are 8 susceptible varieties (41.0 ~ 52.0), respectively, 206, Xundan 20, Xiangyu 335, Kinsey 29, Ludan 661, Zhongnongda 236, Ludan 981 and Kinsey 6850. There were 5 varieties with anti-sliver disease in the range of 31-40 Is Qidan No.1, Zhongnongda 311, Limin15, Wanyu17 and Dongdan80; there are 5 varieties resistant to chondrosis (pathological index is 14.1 ~ 30.0), they are No.4 in Zhongke and No.9 in Shangdan , Luyu 35, Lu Dan 6018 and Luyu 16; two varieties with high resistance to chondrosis (pathogen at 0 ~ 14.0) were Denghai 3 and Nongda 108 respectively.
