Soybean ( (L.) Merrill) is globally valued for protein, oil, and biofuel applications. Thailand imports 99.8% of its soybean consumption due to declining cultivation areas. Northeastern Thailand presents substantial potential for expanding soybean production through integrated seed rotation systems in post-sugarcane (upland) and post-rice (lowland) environments. This study evaluated the newly developed 'Morkhor 60' soybean variety compared to three commercial varieties (SJ 5, 223*Lh-85, and CM 60) across thirteen diverse environments in Northeastern Thailand during 2022-2023. Field experiments employed a randomized complete block design with four replications per site. The 'Morkhor 60' demonstrated favorable yield stability and competitive performance across most environments. The variety showed broad adaptability across soil types (sandy loam to clay) and seasonal conditions (rainy and dry seasons) with minimal genotype-by-environment interactions. Chemical analysis revealed favorable protein content (39.63%) and oil content (14.66%). These findings support the cultivation of 'Morkhor 60' in integrated seed rotation systems, offering a viable strategy to reduce national soybean seed shortages while enhancing domestic production and agricultural sustainability.
大豆（(L.) Merrill）因其蛋白质、油脂和生物燃料应用而在全球受到重视。由于种植面积减少，泰国99.8%的大豆消费依赖进口。泰国东北部通过甘蔗后作（旱地）和水稻后作（水田）环境中的综合轮作系统扩大大豆生产具有巨大潜力。本研究在2022 - 2023年期间，于泰国东北部的13个不同环境中，将新培育的‘莫尔霍尔60’大豆品种与三个商业品种（SJ 5、223*Lh - 85和CM 60）进行了比较。田间试验采用随机完全区组设计，每个地点设置4次重复。‘莫尔霍尔60’在大多数环境中表现出良好的产量稳定性和竞争性能。该品种在不同土壤类型（砂壤土到黏土）和季节条件（雨季和旱季）下均表现出广泛的适应性，基因型与环境的互作极小。化学分析显示其蛋白质含量（39.63%）和油脂含量（14.66%）良好。这些研究结果支持在综合轮作系统中种植‘莫尔霍尔60’，这为减少该国大豆种子短缺、提高国内产量和农业可持续性提供了一个可行的策略。
