揭示青稞品质的内在影响因子，为青稞产业多元化、绿色、持续发展提供有力支撑。以近年来选育的12个优异青稞品种(系)为试验材料，利用因子分析法对14个性状进行分析，并对分析结果进行了Promax斜旋转。结果表明，在2次综合评价中，202004的综合评分均居第1位，可作为新品种进行后续品种区域试验。202055、202035和对照品种陇稞1号的综合评分居前4位，可作为青稞育种过程中的改良亲本。另外，202122、202029、202036品种(系)的排序靠后，但部分主因子得分较高，可作为性状改良的资源加以利用。

This study aims to reveal the intrinsic influencing factors of highland barley quality and to provide strong support for the diversified, green, and sustainable development of the highland barley industry. 12 elite highland barley varieties (lines) developed in recent years were used as experimental materials. 14 traits were analyzed using factor analysis, followed by Promax oblique rotation. The results showed that in two rounds of comprehensive evaluation, 202004 ranked first in the comprehensive score and was suitable for subsequent regional variety experiment as a new cultivar. 202055, 202035, and the control variety Longke 1 ranked among the top 4 and could be used as improved parents in highland barley breeding. In addition, although 202122, 202029, and 202036 ranked lower overall, they had high scores in some principal factors and could be used as resources for trait improvement.
