摘　　要：为进一步了解小麦新品种盐麦2号的特征特性和利用价值,根据2018—2020年江苏省淮南地区(淮河以南)江苏里下河地区农业科学研究所科企小麦联合体区域试验以及生产试验结果,运用产量比较、变异系数、高稳系数和回归系数等分析方法对盐麦2号的丰产性、稳产性以及适应性数据进行分析。结果表明:盐麦2号连续3年参试的实际产量均高于500 kg/667 m~2,在不同年度间实际产量的变异系数为2.19%,数值较小,连续3年的回归系数均略大于且很接近于1,说明盐麦2号丰产性突出、稳产性好、适应性适中,适宜在江苏省淮南麦区种植推广。The current research investigated the characteristics and use value of the new wheat variety Yanmai No.2. Its yielding ability,yield stability, and adaptability were evaluated according to the following methods: yield comparison;and analyses of variation coefficient, high stability coefficient, and regression coefficient. These analyses were performed based on the data of the wheat regional trials and production trials conducted by Agricultural Sciences Institute in Jiangsu Lixiahe Area collaborating with enterprises in Huainan area(the south of Huaihe River) from 2018 to 2020. The actual yields of Yanmai No.2 consistently exceeded 500 kg/667 m~2 in the three consecutive years. The variation coefficient of its actual yield between different years was 2.19%, which was relatively small, and the regression coefficient was slightly larger than, and very close to, 1 in the three consecutive years. The above results showed that Yanmai No.2 has a high yielding capacity, yield stability, and adaptability, suggesting that this new wheat variety is suitable for planting and promotion in Huainan wheat-planting area of Jiangsu Province.
