| 摘 要： | 本试验以小麦品种平原50、东方红3号、陕西蚂蚱、农大198为材料,以小麦条锈病混合菌种接种,研究了温室条件下成株期小麦条锈病反应型—产孢量之间的关系,并在此基础上提出了相对抗病性综合指数的概念(0≤RRCI≤1),作为品种抗条锈性的综合指标。

| Abstract: | A preliminary experiment was conducted to estimate the quantitative relationship between infection type and spore yield of wheat stripe rust on mature plants.It was found that lesions of different infection types produced significantly different amounts of spores per square centimeter(cm2),just as R.Johnson (1976) had reported with seedling experiment Reaction type weights(RTW)were deduced as 0,0.01,0.16,0.51 and 1 for reaction types 0,1,2,3,4 respectively,based on the experiment result with adult plants,an... |
