大豆新品种洛豆1号高产稳产性及适应性分析

Analysis on the Yield Potential, Stability and Adaptability of Soybean Variety Luodou 1

根据2014—2015年河南省大豆区域试验资料,采用高稳系数、Shukla方差、品种离优度对洛豆1号的高产性、稳产性进行了分析。结果表明:洛豆1号两年的高稳系数分别为85.29%、79.92%,均处于较高水平;Shukla方差分别为3.32%、2.506%,分别居第4、第2位;离优度分别为185.40、290.88,均居第2位。说明洛豆1号是一个高产稳产适应性好的大豆品种。并探讨了品种稳产性参数的可靠性。

Based on regional soybean experiments in Henan Province during 2014-2015, this thesis analyzes the high and stable yields of Luodou 1 soybean through high-and-stable-yield coeffcient, Shukla variation and degree of deviation from the best soybean variety. According to the results, the highand- stable- yield coefficients of Luodou 1 soybean were relatively high at 85.29% and 79.92% respectively in 2014 and 2015. The Shukla variations were 3.32% and 2.506%, ranking the fourth and the second respectively. The degree of deviations were 185.40 and 290.88, both ranking the second. The above results show that Luodou 1 soybean is a variety with high and stable yields as well as high adaptability. The thesis also digs into the reliability of the stable yield coefficient.
