Abstract:

Abstract: The high yield, quality and adaptability of 17 new varieties (strains) of oat were analyzed by GGE Biplot under the semi-arid farming-pastoral zone in the northern foot of Yinshan Mountain，and provided basis for sellecting new varieties of oats with high yield and quality. The results showed that: the straw yield of H44 was the highest, the grain yield of KeYan No.1 was the highest, the protein and fat content of 2004R-17 was the highest, the content of β-glucan of Bayou No.10 was the highest and the content of lysine of Bayou No.8 was the highest. The correlation analysis indicated that the grain yield was significantly correlated with the number of spikelets and 1000-grain weight, and the yield of straw was also significantly correlated with plant height、tiller number and the number of spikelets. The number of spikelets and grains per spike ,and grain yield or the straw yield had a negative correlation. Lysine and β-glucan、β-glucan and fat、fat and protein showed a significant correlation，and Lysine and fat、lysine and protein、β-glucan and protein had a negative correlation.
