Identification of Resistance to Fusarium Head Blight and Quality Analysis of Major Wheat Cultivars in Henan Province
摘要
Abstract
In order to provide a basis for fusarium head blight (FHB) resistance breeding and disease control,the resistance and quality of 28 major wheat cultivars were tested in Henan province.The results showed that there was significant negative correlation between 1 000-grain weight and disease index/average response level.In 28 wheat cultivars tested,one cultivar (3.57％ of those tested) was moderately resistant,six cultivars (21.43％ of those tested) were moderately susceptible to FHB,and the 1 000-grain weight decreased by 4.55％ and 4.56％-44.76％ respectively under spray inoculation.Similarly,one cultivar (3.57％ of those tested) was moderately resistant,four cultivars (14.29％ of those tested) were moderately susceptible to FHB,and the 1 000-grain weight decreased by 8.50％ and 5.73％-12.99％ respectively under syring inoculation.There was a significant negative correlation between test weight and disease index/average response level,and a significant positive correlation between 1 000-grain weight and water absorption.Wet gluten content,sedimentation value,extensibility and extension area were decreased at different degree by spray inoculation.Protein content,wet gluten content,sedimentation value,stability time,extensibility and extension were decreased at different degree by syring inoculation.The analysis showed that the optimal cultivar of quality synthetic index was Zhengmai 9023 by GGE biplot.It was noticed that the resistance of major wheat cultivars to FHB was deficient in Henan province,and FHB would decrease the quality of susceptible cultivars.Therefore,it was necessary to strengthen screening and breeding of wheat cultivars with resistance to FHB.关键词
