| 本研究明确了黄淮冬麦区主栽小麦品种对赤霉病的抗侵染、抗扩展、抗毒素积累和抗籽粒侵染能力以及几种抗性之间的相互关系, 并检测了各品种是否带有FHB1抗性基因, 旨在为该区小麦赤霉病抗性鉴定评价、抗性品种培育和利用提供科学依据。小麦赤霉病综合抗性鉴定结果表明:22个黄淮冬麦区主栽品种中, 有20个为感病品种, 只有‘郑麦9023’和‘西农979’为中感品种, 所有品种均不含FHB1基因; 长江中下游麦区的9个品种中, ‘扬麦17’和‘宁麦9号’等6个品种表现中抗, ‘扬麦23’表现中感, ‘苏麦3号’和‘扬麦21’表现抗, ‘扬麦14’‘扬麦17’和‘扬麦23’不含有FHB1基因, 其他品种均含FHB1基因。小麦品种的抗扩展能力与抗侵染能力无显著相关性(r=0.27, P>0.05); 两种接种条件下小麦品种的病粒率与抗脱氧雪腐镰刀菌烯醇(DON)毒素积累能力呈极显著正相关(r=0.86, P<0.01; r=0.88, P<0.01); 单小花滴注法接种条件下, 小麦品种的平均病级与病粒率和籽粒中DON含量都呈极显著正相关(r=0.71, P<0.01; r=0.81, P<0.01); 喷雾接种条件下, 小麦品种的病小穗率与平均病级、病粒率、籽粒中DON含量和ZEN含量都呈极显著正相关(r=0.78, P<0.01; r=0.73, P<0.01; r=0.78, P<0.01; r=0.63, P<0.01)。在毒素积累抗性上, DON含量和ZEN含量呈极显著正相关(r=0.70, P<0.01)。在目前黄淮冬麦区没有中抗品种的情况下, 可以增加育种和鉴定目标为抗籽粒侵染和抗毒素积累的品种, 在小麦品种推广过程中加以运用, 可以达到较好的效果。 |

| The purpose of this paper is to understand the comprehensive resistance of main wheat cultivars to Fusarium head blight (FHB) in the Huanghuai winter wheat region and detect their FHB1 resistance genes, so as to provide new ideas for FHB resistance identification and breeding strategies in this region. The evaluation results of the comprehensive resistance to FHB showed that 20 of the 22 main winter wheat cultivars in the Huanghuaihai region were susceptible, and only ‘Zhengmai 9023’ and ‘Xinong 979’ were moderately susceptible, and all the 22 wheat cultivars did not contain FHB1 gene. Six of the nine wheat cultivars in the middle and lower reaches of the Yangtze River, such as ‘Yangmai 17’ and ‘Ningmai 9’, were moderately resistant; ‘Yangmai 23’ was moderately susceptible, and ‘Sumai 3’ and ‘Yangmai 21’ were resistant. ‘Yangmai 14’ ‘Yangmai 17’ and ‘Yangmai 23’ did not contain FHB1 gene, while other varieties contained FHB1 gene. There was no significant correlation between the disease severity under the single-spikelet point inoculation (the resistance to spread of blight symptoms within a spike) and infected spikelet rate under the spray inoculation (the resistance to initial infection) (r=0.27, P>0.05); the percentage of scabbed kernels of wheat cultivars was positively correlated with DON accumulation under the two inoculation conditions (r=0.86, P<0.01; r=0.88, P<0.01); the disease severity was significantly positively correlated with the percentage of scabbed kernels and DON accumulation under the single-spikelet point inoculation (r=0.71, P<0.01, r=0.81, P<0.01); under the spray inoculation conditions, infected spikelet rate was significantly positively correlated with the disease severity, percentage of scabbed kernels, content of DON, content of ZEN (r=0.78, P<0.01; r=0.73, P<0.01; r=0.78, P<0.01; r=0.63, P<0.01). There was a significant positive correlation between the DON content and ZEN accumulation under the spray inoculation (r=0.70, P<0.01). In the absence of moderately resistant cultivars in the Huanghuai winter wheat region, the cultivars with resistance to kernel infection and DON accumulation should be applied for a better production of wheat. |
