连续3年用单花注滴法接种,考察了穗轴发病时间、病小穗数和穗轴病节片数3个抗性指标。结果表明,病小穗数这一指标能较明确地划分出高抗、中抗、感病3种类型,且稳定性最好。以病小穗数作为主要的抗病性鉴定指标,再参考穗轴病节片数,对小麦品种抗病性的评价及育种材料抗病性的鉴定较为准确、实用。 Three consecutive years with a single injection method of instillation, investigated the cob onset time, the number of sick spikes and coleoptile section number 3 resistance markers. The results showed that the index of disease spikelets can be more clearly divided into high resistance, resistance, susceptibility three types, and the best stability. Taking the number of spikelets as the main index of disease resistance identification, referring to the number of coleopathies, the evaluation of disease resistance of wheat cultivars and the identification of disease resistance of breeding materials are more accurate and practical.
