Introduction and Screening of New Spring Cabbage Varieties and Comprehensive Evaluation of Their Agronomic Traits in the Yellow River-irrigated Areas
摘要
Abstract
To select spring cabbage varieties suitable for cultivation in the Yellow River-irrigated areas with superior overall agronomic performance,thereby improving the overall efficiency of the local vegetable industry and establishing a solid foundation for the development and breeding of cabbage in this region,10 introduced spring cabbage varieties were used as experimental materials.13 agronomic traits,including plant height,plant spread,outer leaf length,outer leaf width,number of outer leaves,number of outer leaf layers,outer leaf weight,leaf ball transverse diameter,leaf ball longitudinal diameter,central column length,central column width,single leaf ball weight,and growth period,were subjected to variation analysis,correlation analysis,principal component analysis,and cluster analysis,and yield differences were evaluated.Results showed that the coefficient of variation for outer leaf weight was the highest,at 18.38%,while the coefficient of variation for central column width was the lowest,at 4.09%.Significant positive correlation was detected between plant height and central column length,outer leaf width and outer leaf weight,and leaf ball longitudinal diameter and outer leaf weight,and a highly significant positive correlation between leaf ball transverse diameter and outer leaf width,outer leaf weight,and leaf ball longitudinal diameter,respectively.Principal component analysis classified 13 agronomic traits into 4 principal components,namely spherical factor,single plant yield factor,plant height factor,and central column factor,which contributed 85.44%to the cumulative variance of the comprehensive performance.Phenotypic clustering analysis divided 10 varieties into 3 groups:high-yield population with longer growth period,medium-yield population with longer central column,and medium-yield population with moderate overall traits.Through comprehensive scoring and yield variance analysis,Tianganjiamei,Yingan 1,and Jiegan 188 were selected as spring cabbage varieties with outstanding comprehensive traits,with yields of 132 681.22 kg/ha,125 667.30 kg/ha,and 115 454.28 kg/ha,respectively,representing yield increases of 8.80%,3.04%,and-5.33%over the control variety Zhonggan 21,respectively.These varieties can be recommended for cultivation as suitable spring cabbage varieties for the Yellow River-irrigated areas.关键词
