摘要

豇豆（Vigna unguiculata， L.）是一种重要的豆科植物，具有很高的营养价值和经济价值，能很好地适应干旱、高温和生物胁迫。关于加纳豇豆品系生长和产量的有限数据促使在Berekum West对15个品系进行品种开发评估。该研究于2021年的主要和次要季节在加纳波诺地区Berekum West市的三个地点（Nyekyemam、Mantukwa和Prosu）进行。试验采用随机完全区组设计（RCBD）， 3个重复。数据分析采用GenStat统计软件第12版。利用AMMI稳定性分析对豇豆品系在不同环境下的稳定性进行了评价。分析表明，生长和产量参数之间存在显著差异。在3种环境下，育科红基因型表现最好，平均产量分别为392.00、370.1和380.6 kg/ha，而UCC Early基因型表现最差。稳定性分析表明，优克红是表现最好的基因型，基因型Rank值最低，为1。y - kpitio White是最稳定的基因型，AMMI稳定值（ASV）和Rank AMMI稳定值（RASV）最低。库姆-佐雅的产量稳定指数（YSI）最高，表现出高产与稳定的良好平衡。由于其适应性强，结实性好，在不同的农作季节产量可靠，农民应优先种植育克红。

Agronomic evaluation of cowpea (Vigna unguiculata L.) lines for varietal development in the Brekum West municipality of Ghana

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
