摘要
Abstract
16 sweet potato varieties were used to comprehensively evaluate their agronomic traits and yield through grey correlation analysis and principal component analysis.The results showed that the coefficient of variation for seven agronomic traits ranged from 20.24%to 45.65%.Fresh tuber yield exhibited significant positive correlations with stem diameter and marketable tuber rate.The contribution degree ranking of agronomic traits to yield was:tuberization rate>stem thickness>leaf area>number of branches per plant>longest vine length>number of tubers per plant.The top three varieties ranked by principal component analysis matched the top three in fresh tuber yield rankings,albeit with slight positional variations.Selected sweet potato varieties Pusui 32,Shangshu 19,and Hami are suitable for demonstration and promotion in the Linzhou region.关键词
