摘要
为了明确黑龙江常规种植芸豆品种抗蚜性,本文利用室内盆栽接虫法,调查芸豆不同品种上豆蚜发生数量,并分析芸豆形态指标与抗蚜性的相关性。结果表明,接豆蚜10 d后,不同品种芸豆上豆蚜虫口密度在26.0~178.7头/株之间,蚜量比值在0.27~1.89之间。蚜量比值低于0.50的高抗品种有‘海军白’‘塔吉克斯坦’‘柱红’,蚜量比值高于1.70的高感品种为‘柱紫’。芸豆不同品种叶片面积、叶色、叶片厚度、叶片含水量、叶毛着生方式和数量均存在一定差异,其中蚜量比值与芸豆叶片正、反面叶毛数均呈极显著负相关,与叶片厚度呈现显著正相关,可以将这3个指标作为评价芸豆抗蚜性的形态指标。本研究为豆科作物抗蚜性的形态学评价提供了方法参考,明确了抗蚜芸豆新品种的选育方向,可为生产实践推荐高抗蚜性芸豆品种以减轻豆蚜造成的产量损失,降低农药使用量,加快抗蚜种质资源的创新与推广。
To evaluate the resistance of commonly cultivated kidney bean varieties in Heilongjiang province to bean aphids,this study employed an indoor pot-based infestation method to assess bean aphid population development on different varieties and analyzed the correlation between morphological characteristics of kidney beans and their aphids resistance.The results showed that 10 days after inoculation with bean aphids,the aphid population density on different kidney bean varieties ranged from 26.0 to 178.7 aphids per plant,and the aphid number ratio ranged from 0.27 to 1.89.The highly aphid-resistant varieties exhibiting an aphid number ratio of less than 0.50 were‘Navy White’‘Tajikistan’and‘Zhuhong’,while the highly aphid-susceptible variety with an aphid number ratio exceeding 1.70 was‘Zhuzi’.There were some differences in leaf area,leaf color,leaf thickness,leaf water content,leaf hair growth status and number among different kidney bean varieties.Among them,the aphid number ratio was extremely significantly negatively correlated with the number of adaxial and abaxial leaf hairs,and significantly positively correlated with leaf thickness.These three indicators can be used as morphological indicators to measure the aphid resistance of kidney beans.This study provides a methodological reference for the morphological evaluation of bean aphid resistance in leguminous crops clarifies,the breeding of new aphid-resistant kidney bean varieties and can facilitate the screening and popularization of highly aphid-resistant kidney bean varieties in production practice to mitigate yield losses induced by bean aphids,reduce pesticide application rates,accelerate the innovation and extension of aphid-resistant germplasm resources.
