Identification of stable resistant wild pigeonpea donors to multiple predominant bruchid species in India.

ABSTRACT: Identifying stable-resistant sources offers an eco-friendly and sustainable insect management strategy. Sixty-eight wild pigeonpea accessions were systematically screened against three predominant bruchid species (Callosobruchus analis, C. chinensis, C. maculatus) using a high-throughput screening pipeline at Kanpur, India, from 2021 to 2024. Resistance classification was based on seed damage and susceptibility index. Four Rhyncosia bracteata accessions consistently exhibited convergent and complete resistance across species, while few C. scarabaeoides accessions were resistant to C. chinensis and C. maculatus but moderately stable against C. analis. Multivariate analyses revealed significant species- and condition-driven variation, with seed damage, emergence and developmental period, as
