<div>Mungbean is one of the most important grain legumes with high-quality dietary protein in India as well in many other Asian countries. But the crop is severely affected by bruchids (Callosobruchus spp.) from field to storage condition. These storage pests not only affect the yield but also reduce the market value and quality of the crops. The chemical method of bruchid management is not economical and environmentally unsafe. So, the host-plant resistance to bruchids would be the best alternative and most sustainable way to control the bruchid. A very limited number of wild accessions and cultivated genotypes are available for the transfer of bruchid resistance gene through conventional breeding. Thus, insights into the molecular mechanism of resistance will help to find out the resistance genes/QTLs easily with the support of available genome sequence and that can be introgressed to the cultivated varieties through marker-assisted backcross breeding (MABB) approach. Therefore, in this review, we focused on QTL mapping, identification of novel QTLs, marker assisted-selection, genomics and transcriptomics study by using advanced molecular tools which will be very helpful for genomic-assisted breeding in mungbean for bruchid resistance.</div>

​Advances in Molecular Breeding for Bruchid (Callosobruchus spp.) Resistance in Mungbean [Vigna radiata (L.) Wilczek]: A Review

<div>Bruchid (Callosobruchus spp.) are the most destructive, notorious storage pest of pulses in the tropical and sub-tropical region. The yield losses are higher than half of the expected yield with in the short period of time. Bruchid initial infestation started in the field and shortly builds up during storage time and cause severe seed damage up to 100 per cent. Bruchid infestation ranges from 60 to 100% within two to three months of storage period. Among the different bruchid species, cowpea weevils (C. maculatus F.) and azuki bean weevils (Callosobruchus chinensis L.) are the most destructive storage pest of pulses. Though several options are now available to identify the elite genotypes against bruchid infestation, still the development of genotypes with sufficient level of host plant resistance is not achieved. In this pursuit, the present article has given a detailed review of the major species of bruchid, insect life style, management practices, screening technique, sources of resistance, novel breeding strategies and recent advancements including use of molecular markers in marker aided selection and QTL studies for bruchid resistance.</div>

Bruchid a Serious Pest on Pulse Crops: Its Control Measures and Breeding Advancements: A Review

<div>Background: Bruchid beetle (Callosobruchus chinensis) is one of the devastating field carry over storage pest causing a huge crop loss, especially in greengram. The pre-breeding lines were developed by crossing between a cultivated variety, VBN (Gg) 2 and Vigna radiata var. sublobata, a progenitor species of greengram used as a resistant parent against bruchid. 
 
Methods: A total of 53 stabilized inter sub-specific lines along with parents were screened for bruchid resistance by &lsquo;no choice&rsquo; method with two replications. Screening parameters were recorded for all the 53 lines and were statistically analysed. Damage assessment was carried out and the three resistant lines obtained during initial screening was further confirmed.&nbsp; 
 
Result: The low seed damage per cent was observed in three lines viz., GGISC-2 (18.00), GGISC-21 (20.00) and GGISC-49 (14.00). The susceptibility index was 0.048, 0.049 and 0.048 in GGISC-2, GGISC-21 and GGISC-49, respectively and hence, classified as bruchid resistant. Delayed adult emergence, uneven adult emergence, prolonged developmental period, small and malformed adults were the other parameters observed in resistant lines. The three resistant lines identified could be further utilized in the breeding programmes for the development of bruchid resistant varieties in greengram.</div>
