湖北省主栽莲品种(系)的抗蚜性鉴定及抗蚜理化性状分析
Identification of aphid resistance and analysis of physicochemical traits of the major lotus cultivars in Hubei Province
摘要
Abstract
In order to provide reference for the breeding of lotus(Nelumbo nucifera)resistant to the wa-terlily aphid Rhopalosiphum nymphaeae,this study identified aphid resistance of 18 main lotus varieties(lines)in Hubei Province using the aphid-ratio method and conducted correlation analysis between the ultrastructure of lotus leaves and the contents of wax,lignin,and flavonoids and aphid resistance.The results showed that the aphid resistance of the 18 lotus varieties(lines)could be divided into six levels,i.e.Elian 12 being highly resistant,Baiyuzan 1,Baiyuzan 2,Baiyuzan 3,and Ezilian 1 being moderately resistant,Ezilian 2,Elian 5,Space 36,Elian 9,and Jianxuan 17 being low resistant,while Wuyuezao,Elian 6,and Bayuefen being low susceptible,Xiaobaipang and Baozi'ou-1 being moderately suscepti-ble,and Baozi'ou-4,Xiangfen,and Dabaipang being highly susceptible.There was no significant corre-lation between the density of papillae,stomata,and petiole spines on the surface of lotus leaves and the aphid-ratio;and there was a significant negative correlation among the wax content,lignin content,and flavonoid content of lotus leaves and the aphid-ratio.In summary,there were significant differences in aphid resistance among the 18 lotus varieties(lines)in Hubei Province.The moderately and highly resis-tant varieties(lines)are worthy of further extension,while the moderately and highly susceptible variet-ies(lines)should be paid attention to aphid control in early developmental stages of lotus.The higher the content of wax,lignin,and flavonoids in lotus leaves,the stronger the aphid-resistance of the lotus vari-ety(lines),and these traits can be used as chemical trait indicators for future aphid resistant breeding.关键词
