Abstract

Cowpea (Vigna unguiculata (L.) is a vital legume with high nutritional and economic value, well-adapted to drought, heat, and biotic stresses. Limited data on the growth and yield of Ghanaian cowpea lines prompted the evaluation of 15 lines in Berekum West for varietal development. The study was conducted across three locations (Nyekyemam, Mantukwa, and Prosu) in the Berekum West municipality in the Bono Region of Ghana during the major and minor seasons of 2021. The experiment followed a randomized complete block design (RCBD) with three replications. Data were analyzed using GenStat Statistical Software 12th Edition. AMMI stability analysis was also used to assess the stability of the cowpea lines across the environments. The analysis revealed significant differences among the growth and yield parameters. Genotype Yok-Kpitio Red performed best across the three environments with mean yield values of 392.00, 370.1, and 380.6 kg/ha, while the least performing genotype was UCC Early. Stability analysis identified Yok-Kpitio Red as the top-performing genotype with the lowest Genotype Rank value of 1. Yok-Kpitio White was the most stable genotype with the lowest AMMI Stability Value (ASV) and Rank AMMI Stability Value (RASV). Kum-Zoya had the highest Yield Stability Index (YSI) value, showing a good balance between high yield and stability. Farmers should prioritize cultivating Yok-Kpitio Red for its adaptability, robustness, and reliable yields during different farming seasons.

期刊介绍： Ecological Genetics and Genomics publishes ecological studies of broad interest that provide significant insight into ecological interactions or/ and species diversification. New data in these areas are published as research papers, or methods and resource reports that provide novel information on technologies or tools that will be of interest to a broad readership. Complete data sets are shared where appropriate. The journal also provides Reviews, and Perspectives articles, which present commentary on the latest advances published both here and elsewhere, placing such progress in its broader biological context. Topics include: -metagenomics -population genetics/genomics -evolutionary ecology -conservation and molecular adaptation -speciation genetics -environmental and marine genomics -ecological simulation -genomic divergence of organisms
