摘要

在埃塞俄比亚,花生既是粮食作物,也是经济作物,发挥着重要作用。它在埃塞俄比亚的生产被发现受到几种生物和非生物因素的限制。为此,本研究的目的是在2019年鉴定高产、生物和非生物抗性或耐受性品种。共对6个品种进行了RCBD评价。AMMI结果表明,环境、品种及其互作效应存在显著差异。AMMI双图对各品种的稳定性和高产能力进行了较为直观的描述。不同环境下,各品种间种子产量差异显著。品种G1 (Bulki)、G6 (Babile2)和G4 (Werer962)专门适应高产环境。G2(舒拉米兹)是最不稳定的品种。G1 (Bulki)比其他品种更稳定。在GGE双图中;IPCA 1和IPCA 2对花生品种环境互作的贡献率分别为48.07%和25.93%,总贡献率为74.00%。因此,Bulki (1075kg ha -1)和Babile2 (1030kg ha -1)是研究区和类似农业生态最稳定的推荐品种,而Fedis是花生生产的理想环境。关键词:AMMI, G x E相互作用,花生DOI: 10.7176/FSQM/102-04出版日期:2020年11月30日

Performance Evaluation of Groundnut Varieties in Eastern Parts of Ethiopia
Groundnut plays an important role as a food as well as cash crop in Ethiopia. Its production in Ethiopia is found to be constrained by several biotic and abiotic factors. To this end, this study was done with the objective of identifying the high yielding, biotic and abiotic resistance or tolerance varieties in 2019. A total of six varieties were evaluated in RCBD. AMMI showed that environments, varieties and their interaction effects were significantly different. The stability and high yielding ability of the varieties has been graphically depicted by the AMMI bi-plot. The variation for seed yield among the varieties for each variety was significant at different environments. Varieties G1 (Bulki), G6 (Babile2) and G4 (Werer962) were specifically adapted to high yielding environments. G2 (Shulamiz) was the most unstable variety. G1 (Bulki) was more stable in comparison to other varieties. In GGE bi-plot; IPCA 1 and IPCA 2 explained 48.07% and 25.93%, respectively, of groundnut variety by environment interaction and made a total of 74.00% of variation. Therefore, Bulki (1075kg ha -1 ) and Babile2 (1030kg ha -1 ) were most stable recommended for the study area and similar agro-ecologies and Fedis was the ideal environment for groundnut production.
