Pigeon pea (Cajanus cajan) is an important orphan crop mainly grown by smallholder farmers in India and Africa. Here, we present the first pigeon pea pangenome based on 89 accessions mainly from India and the Philippines, showing that there is significant genetic diversity in Philippine individuals that is not present in Indian individuals. Annotation of variable genes suggests that they are associated with self-fertilization and response to disease. We identified 225 SNPs associated with nine agronomically important traits over three locations and two different time points, with SNPs associated with genes for transcription factors and kinases. These results will lead the way to an improved pigeon pea breeding programme.
兵豆（Cajanus cajan）是一种重要的孤儿作物，主要由印度和非洲的小农种植。在这里，我们展示了第一个基于 89 个主要来自印度和菲律宾的兵豆个体的兵豆泛基因组，表明菲律宾个体存在显著的遗传多样性，而印度个体则没有。可变基因的注释表明，它们与自交和对疾病的反应有关。我们在三个地点和两个不同的时间点鉴定了与九个农艺性状相关的 225 个 SNP，其中与转录因子和激酶基因相关的 SNP 与九个农艺性状相关。这些结果将为改良兵豆的育种计划铺平道路。
