冀东滨海区玉米品种抗旱鉴定

Identification of Drought Resiatance of Maize Varieties in Coastal Areas of East Hebei

为确定玉米在冀东滨海区的抗旱表现,按河北省地方标准"农作物品种抗旱性鉴定规程"(DB13/T398.5-1999),对12个玉米品种在冀东滨海区干旱胁迫和非干旱胁迫下的产量和抗旱指数进行了鉴定。结果表明,富友一号、丹玉86、东单66号、东单19号、沈玉18、邯丰79的产量和抗旱指数都高于对照品种农大108,具有较好的抗旱性,适宜在该地区干旱条件下栽培。

In order to determine the drought resistance of maize in coastal areas of east Hebei, the yields and resistant indexes of twelve maize varieties were studied under the circumstance of drought stress and non-drought stress in coastal areas of east Hebei. This study was done in accordance with the local standard ＂identification order of crop varieties drought resistance＂. The results indicated that the yields and drought resistance indexes of Fuyoul, Danyu 86, Dongdan 19, Shenyu 18 and Hanfeng 79 were higher than the control variety Nongda 108, which means that these maize varieties have good drought resistance, and therefore are suitable for local planting under drought conditions.
