摘　　要：为准确评价影响藜麦单株产量的农艺性状,对19份藜麦种质资源的8个农艺性状进行相关性分析、灰色关联度分析。结果表明:8个农艺性状的变异系数范围为2.32%~32.99%;株高、生育期、主穗长度、有效分枝与单株产量呈极显著或显著正相关;灰色关联分析表明,与单株产量关联度较高的农艺性状有生育期(0.773 9)、株高(0.743 5)、主穗长度(0.733 5),关联度大小依次为生育期、株高、主穗长度。因此,要想获得藜麦较高的单株产量,应优先考虑以生育期较长、植株高大、主穗较长的品系为主要选育目标。In order to accurately evaluate the agronomic traits affecting the yield o£quinoa per plant,correlation analysis and grey correlation analysis were conducted on 8 agronomic traits of 19 quinoa germplasm resources.The results show that the variation coefficients of 8 agronomic traits ranged from 2.32%to 32.99%.Plant height,growth period,main panicle length and effective branches were significantly or highly positively correlated with yield per plant.The grey correlation analysis shows that the agronomic traits with high correlation with yield per plant are growth period(0.7739),plant height(0.7435)and main panicle length(0.7335),in the order of growth period,plant height and main panicle length.Therefore,in order to obtain higher yield per plant of quinoa,priority should be given to breeding varieties with longer growth period,taller plants and longer main panicles.
