“…Cowpea has a broad diversity in growth habit, flower color and size, and color and shape of pods and seeds (Dareus et al., 2021; Mafakheri et al., 2017; Nkhoma et al., 2020; Sanjeev et al., 2018). A great variation is also found for phenological traits such as days to flowering (DF), days from flowering to pod maturity (DFPM), and days to pod maturity (DPM) (Muñoz‐Amatriaín et al., 2017, 2021; Paudel et al., 2021).…”

Understanding the genetic control of traits linked to phenology is essential to address strategies and efforts in the development of resilient cultivars capable of adapting to climate change. In this study, we performed genome‐wide association studies (GWAS) on a cowpea [Vigna unguiculata (L.) Walp] mini‐core collection to dissect the genetic architecture and identify genomic regions associated with days to flowering (DF), days from flowering to pod maturity (DFPM), and days to pod maturity (DPM). Phenotypic data were collected in two years and used to test associations with 41,533 single‐nucleotide polymorphism (SNP) markers by single and multi‐trait analysis. In addition, we searched for candidate genes putatively involved in phenological traits within genome‐associated regions. The single‐trait approach identified 28 significant marker‐trait associations for the three traits, while the multi‐trait identified 18 significant associations, both evidencing pleiotropic associations. Five of these markers were associated with phenological traits reported in previous studies. Candidate genes were identified, including genes involved in phosphorylation and encoding the maternal effect embryo arrest 60, known to be associated with pod maturity and flowering, respectively. Functional validation of these genes will further improve our understanding of the variation of phenological traits in cowpea and other related crops.This article is protected by copyright.
