Analysis on the High and Stable Yield, and the Adaptability of New Rapeseed Variety Shanyou1609 Based on GGE Biplot

In order to effectively explore the production potential of Shanyou 1609 and realize its large-scale popularization and application, the GGE biplot was used to analyze high yield stability and adaptability of 22 tested varieties of National Winter Rapeseed in Huanghuai region in 2016 and 2017, and comprehensively evaluated Shanyou1609 in combination with important agronomic, quality and resistance traits. The results showed that: Shanyou1609 was closest to the positive direction on the average environmental axis（AEA）, with outstanding yield and good stability. The ideal degree of Shanyou1609 ranked first. Shanyou1609 had a wide adaptability, especially in Yangling, Fuping, Baoji, Dali of Shaanxi, Zhengzhou of Henan and Chengxian of Gansu in which it performed well and was suitable for planting. Compared with the control ’Qinyou7 ’, Shanyou1609 had obvious advantages in planting Winter Rapeseed in Huanghuai region. Shanyou 1609 had high oil quality, better quality multi-resistant, suitable for mechanized production. In summary, Shanyou1609 was an excellent variety with high yield, stable yield and wide adaptability among the tested varieties of National Winter Rapeseed in Huanghuai region group. This study could also provide reference for the comprehensive evaluation of quantitative traits of other crops by GGE biplot analysis.
