Performances and Stabilities of Yield of Tartary Buckwheat Varieties

摘要

Eight tartary buckwheat varieties that had been bred in different regions of China were comparatively tested in Major Tartary Buckwheat Production areas of China and their yields were comprehensively analyzed by non-parametric rank analysis. The results of the comparison and analysis showed that these varieties (lines) significantly differed in high-yield stability, and among them Qianwei 3 was a stable high yield variety thus worthy of extension. Meanwhile, the results of the analysis also indicated that non-parametric rank analysis was capable of evaluating the test varieties (lines) objectively and fairly.
