摘要
为鉴定我国红麻种质资源对根结线虫病的抗病性,在对120份红麻遗传资源进行田间自然发病鉴定的基础上,选择25份有代表性(22份高抗和3份感病)的种质进行盆栽根结线虫病接种鉴定。田间自然发病鉴定结果:120份红麻遗传资源中5个高感、19个中感、25个中抗、71个高抗;其侵染的根结线虫主要为南方根结线虫(Meloidogyne incognita)、爪哇根结线虫(Meloidogyne javanica)和花生根结线虫(Meloidogyne arenria)的混合种群。进行盆栽接种鉴定的25份遗传资源中,7份为中抗,其余分别为中感和高感品种,未发现高抗或免疫品种。本研究可为红麻种质资源发掘利用提供科学依据。
This study was conducted to indentify the resistance against root-knot nematode in 120 kenaf varie- ties using field trials and pot culture. The results showed that the main species of root-knot nematode in the field were Meloidogyne incognita, Meloidogyne javanica, and Meloidogyne arenria. 5,19,25, and 71 varieties of 120 tested varieties were of high susceptibility, middle susceptibility, middle resistance, and high resistance to these root-knot nematodes,respectively. Further study was carried out in representative 25 varieties using pot culture,7 rarities were middle resistance to Meloidogyne incognita,but no highly resistant or immune varieties.
