大豆主要农艺性状与品质性状间的灰色关联度分析

摘要

High yield and good quality are important targets of soybean breeding, and grey relation analysis is one of methods in grey theory. Using the method of grey relation analysis and correlation coefficient k and correlation degree r of agronomic and quality traits, the article analyzed the relations between soybean agronomic and quality characters. The analysis showed that soybean agronomic and quality characters had positive correlation. Yield per plant had the greatest influence on fat and protein content, while hundred seed weight was in the second place. The result provided theoretical evidence for soybean breeding.%　　高产、优质育种是大豆主要育种目标，灰色关联度分析是灰色理论中的一种分析方法，应用灰色关联度分析的这一方法，通过分析农艺性状的各种性状对品质性状的关联系数（k）及关联度r，研究影响品质性状的主要农艺性状及其影响程度，试验分析了大豆主要农艺性状与品质性状之间的关联度，优势分析表明，大豆农艺性状与品质性状为正相关，从关联序可以得出对脂肪含量和蛋白质含量影响最大的是单株产量，其次是百粒重，为大豆育种提供了重要理论依据。
