秦巴山地玉米套种条件下大豆品种丰产及稳产性分析

Analysis on the high yield and stable yield of soybean varieties under the condition of maize interplanting in Qinba mountain area

为选择适宜秦巴山地玉米-大豆套种条件下的高产稳产大豆品种,提高秦巴山区粮油作物的产量及效益。开展了玉米-大豆套作模式下,高产大豆品种的产量稳定性与适应性分析。利用变异系数(CV)、显著性差异、回归系数、高稳系数(HSCi)等方法综合分析了9个大豆品种的丰产性和适应性。结果表明,黑大豆、贡秋豆5号为丰产性、稳产性较好的大豆品种。通过评价分析的高产稳产大豆品种黑大豆和贡秋豆5号可在秦巴山地同类生态环境玉米套种大豆条件下作为高产稳产品种加以应用。

To select high and stable yield soybean varieties suitable for corn-soybean interplanting in Qinba mountainous area to im⁃prove the yield and benefit of grain and oil crops,the stability and adaptability analysis of high-yield soybean varieties under the corn intercropping soybean model was carried out.Using coefficient of variation(CV),significant differences,regression coefficients,high stability coefficient(HSCi),a comprehensive analysis of the adaptability of 9 varieties with a large increase in yield was carried out.The results showed that Heidadou and Gongqiudou No.5 are soybean varieties with good yield and stability.Heidadou and Gongqiudou No.5 can be used as high-yield and stable-yield varieties under the conditions of corn interplanting soybeans in the same ecological environment in the Qinba mountains.
