Genetic Dissection of Azuki Bean Weevil (Callosobruchus chinensis L.) Resistance in Moth Bean (Vigna aconitifolia [Jaqc.] Marechal).

ABSTRACT: The azuki bean weevil (Callosobruchus chinensis L.) is an insect pest responsible for serious postharvest seed loss in leguminous crops. In this study, we performed quantitative trait locus (QTL) mapping of seed resistance to C. chinensis in moth bean (Vigna aconitifolia [Jaqc.] Maréchal). An F₂ population of 188 plants developed by crossing resistant accession 'TN67' (wild type from India; male parent) and susceptible accession 'IPCMO056' (cultivated type from India; female parent) was used for mapping. Seeds of the F₂ population from 2014 and F_2:₃ populations from 2016 and 2017 were bioassayed with C. chinensis, and the percentage of damaged seeds and progress of infestation severity were measured.
