近 10a来对 2 179份选育材料作赤霉病抗性鉴定 ,筛选到 2 9份新抗源 ,抗性水平超过苏麦 3号 ,年度间抗性稳定 ,抗赤遗传背景较丰富。部分新抗源的穗部性状和籽粒外观品质有较大改善 ,但植株仍偏高。本试验鉴定出部分中抗品系的综合农艺丰产性已达到生产上的应用水平。抗性鉴定和评价左右着材料的取舍 ,把握抗赤鉴定尺度 ,妥善处理抗性与其他农艺性状的关系 ,需要育种和鉴定工作者慎重对待 Nearly 10 years, 2 179 screened materials were screened for scab resistance, 29 new resistant sources were screened, and the resistance level exceeded that of Sumai No.3. The resistance was stable during the year and the red background was more abundant. Some of the new anti-source ear traits and grain appearance quality has greatly improved, but the plant is still high. This experiment identified some of the lines of comprehensive agronomic high yield has reached the production level of application. Identification and evaluation of resistance around the choice of materials, grasping the scale of anti-red identification, properly handle the relationship between resistance and other agronomic traits, the need for breeding and identification of workers to be taken
