Identification of Field Resistance to Stem Blight in Chinese Water Chestnut Resources
摘要
Abstract
Resistance identification and evaluation of 30 Chinese water chestnut [ Eleocha-ris tuberosa ( Roxb. ) Roem. et Schult ] resources to stem blight was carried out in field under nature disease occurrence condition by relative resistance index method. 'Yiyangbiqi' was identified as high resistance, Xuanzhouqi-2' and 'Jiangxijiujiangqi' were identified as medium resistance. Meanwhile, it was determined that state of illness investigation in the middle and lower valley of the Yangtze River should be dated in early October ( Chinese water chestnut would be transplanted in in middle and late July ). Using relative resistance index method to identify and evaluate Chinese water chestnut resistance to stem blight could in certain degree eliminate effects of different investigation methods on the accuracy of identification results.关键词
