摘要
通过GGE双标图法分析了17个燕麦新品种(系)在阴山北麓半干旱农牧交错区生态条件下的丰产性、适应性和品质,为筛选高产优质燕麦新品种提供依据。结果表明:H44号的秸秆产量最高,科燕一号的籽粒产量最高,2004R-17的蛋白质和脂肪含量最高,坝莜十号β-葡聚糖含量最高,坝莜八号赖氨酸含量最高。籽粒产量与千粒重和有效穗数呈显著正相关关系,秸秆产量与株高、分蘖数以及有效穗数间也呈正相关关系,小穗数和穗粒数与籽粒产量或者秸秆产量间均呈负相关关系,赖氨酸和β-葡聚糖、β-葡聚糖和脂肪、脂肪和蛋白质呈显著正相关关系,赖氨酸和脂肪、赖氨酸和蛋白质、β-葡聚糖和蛋白质均呈负相关关系。
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.
