“…Meanwhile, to establish the bruchid resistance in cowpea, a thorough understanding of the genetic architecture of this resistance is first required. Recent work has shown that the resistance of cowpea to C. maculatus is not related to traits such as seed weight, seed coat texture and seed coat colour (Cruz et al, 2016; Kpoviessi, Agbahoungba, et al, 2021; Kpoviessi et al, 2020; Lattanzio et al, 2005; Tripathi et al, 2020) but rather related to the biochemical traits such as the primary and secondary metabolic compounds of cowpea seeds, namely, phenols, tannins and carbohydrates (Kpoviessi, Agbahoungba, et al, 2021; Lattanzio et al, 2006). Previous research has also shown that resistance to bruchid is quantitatively inherited (Kpoviessi, Adoukonou‐Sagbadja, et al, 2021; Miesho et al, 2018) and controlled by few genes with large effects (Adjadi et al, 1985; Kpoviessi, Adoukonou‐Sagbadja, et al, 2021; Miesho et al, 2019).…”

Identification of genes associated with bruchid resistance variations in cowpea accessions would help breeders to generate new cowpea cultivars with improved resistance and quality. In this work, 107 cowpea collections from various areas in six countries were phenotyped for their responses to Callosobruchus maculatus and genotyped with Single Nucleotide Polymorphism (SNP) markers. Six multi-locus models Genome Wide Association Study (mrMLM, FASTmrMLM, pKWmEB, pLARmEB, FASTmrEMMA and ISISEM-BLASSO) were used to associate the genotype data to phenotypic cowpea resistance traits: Percentage of Bruchid Emergence (PBE); Percentage of Weight Loss (PWL); Median Development Period (MDP); Dobie Susceptibility Index (DSI); Number of Egg Laid (NEL) and Mean Number of Hole (MNH).Out of 14 QTNs, three were associated with more than one trait and were associated with 11 candidate genes located within 10-30 kb of the QTNs. These candidate genes exhibit functionalities associated with cowpea resistance mechanisms. All these results could contribute to the gene networks in resistant cowpea varieties.The result of this study could also increase our knowledge of genetic resistance of cowpea to bruchids and could be useful for molecular breeding.

“…This is so as more of these compounds were observed in the tolerant varieties than the susceptible varieties. Several compounds have been identified to confer resistance against C. maculatus in cowpea, which include alkaloids, flavonoids, phenols, phenolic acids, and tannins (Kpoviessi et al, 2021;Lattanzio et al, 2005;Ojwang et al, 2012). Hema et al (2022) The co-evolution of plants and their predators has resulted in phytophagous insects adaptation to the deterrent chemicals contained in the plants they feed on (Carlini & Grossi-De-Sá, 2002).…”

The cowpea weevil, Callosobruchus maculatus, is a major threat to stable cowpea production, especially in storage, and has been reported to facilitate postharvest losses in cowpea grains. Host resistance has been suggested as the best control method but with conflicting knowledge on the source of resistance. Hence, the study seeks to evaluate seed storage proteins (SSPs) and seed coat compounds (SCCs) associated with tolerance to C. maculatus. SSPs and SCCs were assayed and associated with C. maculatus tolerance in 19 cowpea varieties with varied tolerance levels using a stepwise multiple regression analysis. Top C. maculatus tolerants were TVu‐2027, TVu‐11952, TVu‐11953, and TVu‐145. The protein fraction with a mass of 51 kDa was a significant predictor associated with percentage adult insect emergence (PAE) and host suitability index (H.S.I.), and 57 and 71 kDa were associated with mean development period (MDP) whereas 59 and 131 kDa were associated with seed damage tolerance (TolSD). Several SCCs identified were associated with the C. maculatus tolerant measures used in the study. However, Thiazole, tetrahydro‐ and Undecane were consistently identified with C. maculatus tolerance. Higher phenotypic variability was accounted for by SCC than SSP fractions associated with C. maculatus tolerance in the study indicating that SCCs contributed more to the C. maculatus tolerance than the SSPs identified. These compounds can be incorporated into breeding for C. maculatus tolerant in cowpea and biopesticide formulations whereas cowpea varieties with the high or significant amount of these compounds can also be recommended to the farmers or to the cowpea producers.

“…CTs in the seed coat can aid in defending the embryo and endosperm from biotic stresses by acting as physical and/or chemical barriers, and via primary germination by preventing the passage of signaling molecules that alter seed dormancy ( Zhou et al., 2021 ). High tannin concentration in cowpea seeds corresponds with resistance to bruchid beetles during storage ( Kpoviessi et al., 2021 ). Rowanberry, blackcurrant, saskatoon berry, and sea buckthorn, as well as numerous Vaccinium species, have high CT concentrations ( de Araujo et al., 2021 ).…”
