Abstract:

Taking 22 Chinese old garden roses as materials，their resistance to powdery mildew were evaluated by isolated identification and field identification，in order to know their powdery mildew resistance.The results showed that the two identification results were almost consistent.There were five moderately resistant varieties (Rosa ‘Pufuhong’，R.‘Ruanxianghong’，R.‘Yunzhengxiawei’，R.‘Sichun’，R.‘Viridiflora’)，12 moderately sensitive varieties (R.‘Yijifen’，R.‘Simianjing’，R.‘Yipinzhuyi’，R.‘Zixiangrong’，R.‘Mudanyueji’，R.‘Yulinglong’，R.‘Jinfenlian’，R.‘Yingrihehua’，R.‘Huzhongyue’，R.‘Chunshuilvbo’，R.‘Yushizhuang’，R.‘Zihongxiang’) and five highly sensitive varieties (R.‘Pallida’，R.‘Dafugui’，R.‘Qinglianxueshi’，R.‘Junang’，R.‘Jinoufanlv’).The results will provide the scientific theoretical basis for rose disease-resistant breeding using Chinese old garden roses in the future.
