Identification of stable resistant wild pigeonpea donors to multiple predominant bruchid species in India.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 key discriminators. Correlation funnel confirmed antibiosis as the predominant resistance mechanism, while antixenosis was species-specific, particularly against C. maculatus. Machine learning model predicted seed and insect traits as major contributors. Factorial Analysis of Mixed D and hierarchical clustering validated biologically meaningful grouping of resistant versus susceptible accessions, with biochemical traits enhancing separation of intermediate classes. Collectively, R. bracteata emerges as a robust multi-species resistance donor, and C. scarabaeoides as a species-specific donor. These multi-species resistant resources act as invaluable resources for introgression breeding to develop bruchid-resistant pigeonpea cultivars and highlight opportunities to dissect biochemical pathways and QTLs underlying resistance.
