基于因子分析的青稞新品系性状评价研究
Study on the Trait Evaluation of New Hulless Barley Lines Based on Factor Analysis
摘要
Abstract
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.关键词
