Several bruchid species attack stored pulses including those belonging to Vigna species.Wild Vigna accessions offer a host of useful traits for improvement of their cultivated types and hence 42 endemic wild Vigna accessions from 13 species were screened against three cosmopolitan bruchid species viz., Callosobruchus maculatus (F.), C. chinensis L. and C. analis (F.). The accessions exhibited varied reactions to three bruchid species and were categorized based on two criteria-seed damage (SD) and susceptibility index (SI). Based on SD, IC251442 accession of V. umbellata was found highly resistant, whereas accessions of V. umbellata (IC251439, PRR 2007-2 and IC251440), V. vexillata (IC248326 and IC248343), V. trilobata (JAP10-5) and V. trineriva var. bournei (IC247407) were found resistant to C. maculatus. Likewise, the accessions of V. mungo var. mungo (IC251390, IC251385 and IC251387), V. vexillata (IC248326) and V. khandalensis (Kumur local) were found highly resistant, whereas the accessions V. umbellata (IC251440), V. mungo var. mungo (IC251397), V. vexillata (IC248343) and V. dalzelliana (IC247408) were found resistant to C. chinensis. Interestingly, none of the accessions was found either highly resistant/resistant to C. analis. Based on SI, several accessions (including those susceptible on the basis of SD) recorded lower SI (<0.05) and were found resistant. A few accessions namely, V. trinervia (JAP 10–51), V. trinervia var. bournei (IC247407), V. pilosa (IC210575, IC210580 and IC210576) and V. dalzelliana (IC203864) were found resistant/moderately resistant to C. chinensis and C. maculatus, whereas the same lines were found moderately susceptible/susceptible against C. analis. The remaining accessions were found to be susceptible/highly susceptible to all bruchid species tested. These resistant lines could be further subjected to biochemical as well as molecular analysis to identify the specific seed components imparting resistance to bruchids. Simultaneously, these may be deployed in introgression breeding to develop bruchid resistant superior cultivars.

几种 bruchid 物种攻击储存的豆类，包括属于豇豆物种的那些。 野生豇豆种质提供了许多有用的特性来改进其栽培类型，因此对来自 13 个物种的42 种地方性野生豇豆种质与三种世界性的 bruchid 物种（即 Callosobruchus maculatus）进行了筛选(F.), C. chinensis L. 和C. analis（F。）。种质对三种 bruchid 物种表现出不同的反应，并根据两个标准进行分类 - 种子损伤 (SD) 和易感性指数 (SI)。根据 SD，发现 V. umbellata 的 IC251442 种质具有高度抗性，而 V. umbellata (IC251439、PRR 2007-2 和 IC251440)、V. vexillata (IC248326 和 IC248343)、V. trilobata-5 (JAP10) 的种质具有高抗性V. trineriva 变种。bournei (IC247407) 被发现对 C. maculatus 具有抗性。同样，V. mungo var. 的种质。发现 mungo (IC251390、IC251385 和 IC251387)、V. vexillata (IC248326) 和 V. khandalensis (Kumur local) 具有高度抗性，而 V. umbell ata (IC251440)、V. mungo var. mungo (IC251397)、V. vexillata (IC248343) 和发现V. dalzelliana (IC247408) 对C. chinensis具有抗性。有趣的是，没有发现任何种质对C. analis具有高度抗性/抗性。基于 SI，一些种质（包括基于 SD 的易感种质）记录了较低的 SI (<0.05) 并被发现具有抗性。一些种质即V. trinervia (JAP 10–51)、V. trinervia var. bournei (IC247407) 、V. pilosa (IC210575、IC210580 和 IC210576)和 V. dalzelliana (IC203864) 被发现对C. chinensis和C. maculatus具有抗性/中度抗性，而相同的品系被发现对C. analis中度敏感/易感。发现剩余的种质对所有测试的 bruchid 物种敏感/高度敏感。这些抗性品系可以进一步进行生化和分子分析，以确定赋予 bruchid 抗性的特定种子成分。同时，这些可以用于基因渗入育种，以开发抗 bruchid 的优良品种。
