黄淮麦区小麦品种(系)黑胚病抗性研究
Study on Resistance of Wheat Varieties to Wheat Black Point Kernel in Huang-Huai Wheat Area
摘要
Abstract
The aim was to understand the incidence and resistance performance of black point disease in major cultivated wheat varieties in the Huang-Huai wheat region.A total of 33 wheat varieties from the region were collected,and the rates of black point kernel in grains and diseased index were statistically analyzed for each variety.Disease index was also analyzed,and the resistance to black point disease was categorized.Significant differences in the rate of black point kernel were observed among the tested wheat varieties(lines),with the rate of black point kernel ranging from 6.17%to 63.17%.Varieties such as'Bainong 607','Bainong 207','Shannong 17','Shannong 116','Weilong 169',and'Xinmai 45'had low rates of black point kernel in grains and a light disease index,all were classified as having a low susceptibility to wheat black point disease;whereas'Zhoumai 36','Zhoumai 28','Gaomai 6','Tunmai 127','Anke 1602',and'Aikang 58'had high rates of black point kernel in grains and a heavy disease index,all were classified as having a high susceptibility to wheat black point disease.There were significant differences in the rate of black point kernel among different wheat varieties in the Huang-Huai wheat region.The research results provide important information for variety selection and disease management in the region,which will help guide agricultural production practices,reduce the occurrence of black point disease,and improve wheat yield and quality.关键词
