Basil ( L.) is a member of the Labiatae family and is one of the most widely consumed aromatic and medicinal plants in many countries due to its numerous properties and uses. The objective of the study was to determine whether landraces are better adapted to water-limited environments compared to commercial cultivars. Irrigation levels and genotypes affected plant height and leaf area index, with 25% and 33% higher values observed under complete irrigation, respectively. Additionally, limited water availability resulted in a 20% reduction in dry matter yield and a 21% reduction in essential oil yield over the three years in all of the genotypes tested, specifically in the lower irrigation treatment (d), compared to the control treatment (d). The landraces that performed the best under limited water supply were Athos white spike (AWS) and Gigas white spike (GWS), indicating their suitability for environments with limited water resources. The results demonstrate that there are landraces that can be utilized in dryland climates with appropriate water management, enabling water conservation and utilization of fields in water-scarce areas for irrigation purposes.
罗勒（唇形科罗勒属）是唇形科植物的一员，由于其具有多种特性和用途，是许多国家消费最为广泛的芳香植物和药用植物之一。本研究的目的是确定地方品种是否比商业栽培品种更能适应水分受限的环境。灌溉水平和基因型影响株高和叶面积指数，在完全灌溉条件下，株高和叶面积指数分别高出25%和33%。此外，与对照处理（d）相比，在所有测试基因型中，特别是在较低灌溉处理（d）下，三年来有限的水分供应导致干物质产量降低20%，精油产量降低21%。在水分供应有限的情况下表现最佳的地方品种是阿索斯白穗（AWS）和吉加斯白穗（GWS），这表明它们适合水资源有限的环境。结果表明，通过适当的水分管理，一些地方品种可用于干旱气候地区，从而实现水资源节约，并在缺水地区利用农田进行灌溉。
