| 中文摘要: |
| 采用人工接种喷雾法对国家甘蔗种质资源圃保存的31份甘蔗野生资源材料进行了抗蔗茅柄锈菌(Puccinia erianthi Padw et Khan)的抗性鉴定。结果表明,31份材料中,高抗材料19份(61.3%),抗性材料3份(9.68%),中抗材料6份(19.36%),中感材料3份(9.68%)。其中斑茅种对蔗茅柄锈菌的抗病性较强,细茎野生种抗病性较差,较易感锈病。 |
| 英文摘要: |
| Thirty-one sugarcane wild germplasm resources chosen from the collections of NNSGR (National Nursery of Sugarcane Germplasm Resources, Kaiyuan, China) were analyzed by spraying inoculation method for identification of their resistance to Puccinia erianthi Padw et Khan. The results showed that 19 of the 31 samples were highly resistant ((61.3%)), 3 of them resistant (9.68%) and 6 of them moderately resistant (19.36%), while 3 of them displayed moderate susceptibility (9.68%). Comparatively speaking, E. arundinaceus displayed higher resistance to P. erianthi, whereas S. spontaneum was more susceptible than other species. |
