Evaluation on aphid resistance of Lonicera plants species by different evaluation methods
The damage of Aphidoidea seriously affects the yield and quality of Lonicera plants.Breeding Aphidoidea resistant varieties is the most economical and effective means to solve the problem of Lonicera plants aphids.Through the evaluation method of Lonicera plants against the aphid,the highly resistant to aphid varieties and germplasm resources are selected for the treatment of aphids.We evaluated the aphid resistance of 27 species Lonicera plants by aphid index method,improved aphid index method,innovative honeydew index method and cluster analysis method.There were significant differences of the aphid resistance.Baiyu1,Yangjiao and Lonicera×tellmanniana were high resistant varieties,accounting for 11.1%.Beihua No.1,Zijingzi,red honeysuckle and Sijihua were high sensitive varieties,accounting for 14.8%.Xiaojizhuahua,Xianhuazi,wild honeysuckle,Jiulu No.1,Fengqiu honeysuckle,Julu honeysuckle,Changzhenzi,Lonicera confusa,Xiaomaohua,Jiufeng No.1,and Shanhuazi were the resistant varieties.Lonicera hypoglauca,Xiaozhenhua,Zhongjin No.1,Yanghuazi,Damaohua,Lonicera similes,Mazhenhua,Jinfeng No.1 and Lonicera macranthoides were the sensitive varieties.Among the four evaluation methods,the evaluation effect of honeydew index method is close to the final judgment result and has clear visual hierarchy.Honeydew index method is simple and feasible,and suitable for aphid resistance evaluation of honeysuckle species.
