“…This is the first report of polygenic inheritance of CLS resistance. In another study, the evaluation of CLS disease in F 2 plants and F 2:3 families derived from a cross between “CSR12906” (susceptible) and “IT90K‐59‐120” (resistant) revealed that the disease scores were continuously distributed, suggesting that the resistance in IT90K‐59‐120 is a quantitative trait (Duangsong, Kaewwongwal, Somta, Chankaew, & Srinives, ).…”

Cowpea (Vigna unguiculata): Genetics, genomics and breeding

Cowpea, Vigna unguiculata (L.), is an important grain legume grown in the tropics where it constitutes a valuable source of protein in the diets of millions of people. Some abiotic and biotic stresses adversely affect its productivity. A review of the genetics, genomics and breeding of cowpea is presented in this article. Cowpea breeding programmes have studied intensively qualitative and quantitative genetics of the crop to better enhance its improvement. A number of initiatives including Tropical Legumes projects have contributed to the development of cowpea genomic resources. Recent progress in the development of consensus genetic map containing 37,372 SNPs mapped to 3,280 bins will strengthen cowpea trait discovery pipeline. Several informative markers associated with quantitative trait loci (QTL) related to desirable attributes of cowpea were generated. Cowpea genetic improvement activities aim at the development of drought tolerant, phosphorus use efficient, bacterial blight and virus resistant lines through exploiting available genetic resources as well as deployment of modern breeding tools that will enhance genetic gain when grown by sub-Saharan Africa farmers.

“…Originally from Central Africa, the cowpea is a leguminous plant, which, thanks to its special biological and morphological characteristics (very strong root system, with a great absorption power, waxy layer on the leaves), can very well capitalize on poorly productive lands in the category of sandy soils, having a high tolerance to thermo-hydric stress conditions, (Sinclair et al, 2015;Abe et al, 2015;Egashira et al, 2016;Sánchez-Navarro et al, 2021;Drăghici et al, 2022). Research results have proven that the plant's metabolism proceeds normally under the conditions of a healthy cultural state, correlated with the direct influence of environmental factors (Hamidou et al, 2007).…”

The study was carried out in the period 2021-2022 at the Research and Development Station for Plant Culture on Sands Dabuleni, Romania, with the aim of finding scientific solutions to reduce the incidence of attack produced by the identified harmful agents in the cowpea crop (Vigna unguiculata L. Walp) sown in the conditions of the sandy soils of southern Oltenia, Romania. Various environmentally friendly products with a fungicidal and insecticidal role were tested, in order to promote sustainable agriculture, by applying two phytosanitary treatments in the phases of 3-4 true leaves and the appearance of flower stalks of the cowpea plant. The results obtained for cowpea highlighted the phytosanitary treatment with the Polyversumbiofungicide, in a dose of 0.1 kg/ha and the Bioinsekt insecticide, in doses of 0.5-1 l/ha, which achieved the best phytosanitary control over the attack produced by plant pests (AD=0.79%), correlated with an increase in resistance to stress conditions (bound water=3.42%; vacuolar juice concentration=10.2%) and high productivity (12.6 pods/plant, leaf index=8.04, production=2725.2 kg/ha).

“…Draft genome sequence of Pseudocercospora cruenta causing black leaf mould of cowpea Introduction Cowpea (Vigna unguiculata) is a widely cultivated legume in tropical and subtropical regions, especially in Africa, Asia, and some parts of America. It serves as a significant source of carbohydrates, protein, minerals and vitamins for human and livestock nutrition in the tropical world (Duangsong et al 2016;Longe 1980;Singh et al 2003). In many countries, cowpea is grown as a major component in cropping systems because of its rapid growth, drought tolerance, and ability to fix atmospheric nitrogen (Duangsong et al 2016;Omoigui et al 2019).…”
