广西桑树品种资源材料对赤锈病的抗性鉴定
Identification of mulberry varieties resistance to red rust in Guangxi
摘要
Abstract
[Objective ]The present study was conducted to verify the red rust resistanee in different mulberry varieties in Guangxi in order to provide resistant materials for mulberry disease resistant varieties breeding programs. [Method]Both,the smearing and covering methods were used to identify the resistance of 7 mulberry varieties through artificial inoculation of the red rust pathogen. The status of natural incidences of red rust in mulberry field was also investigated. [Result]All the tested varieties were found infected by the disease, and the variety Lunjiao 40 was found to have relatively lower diseased index, while the other 6 varieties were found seriously affected with the disease. The incidence of mulberry red rust differed in different years, seasons and geographical areas of mulberry production. Red rust was found happening initially in the first 10-day of Apr, and reaching peak period from Oct to Nov. Higher incidences of mulberry red rust disease were found to occur in areas where mulberry was planted in paddy field and low-lying land, while relatively lower incidences were observed in dry slope areas. [Conclusion]The mulberry variety Lunjiao 40 was found to possess resistance against the red rust disease and may be recommended as an intermediate material or parent in disease resistance breeding programs.关键词
