以相关分析法研究了23个国外高粱品种9个主要性状与耐瘠性的相关关系。结果表明，多数性状与耐瘠性为不显著相关，只有穗粒数、株高与耐瘠性相关关系显著。通径分析表明，株高对耐瘠性的直接作用最大，其次为千粒重和一级枝梗数。对株高、千粒重、一级枝梗数进行选择可有效提高品种耐瘠性的选择效果。
Correlation analysis was used to study the relationship between 9 main traits of 23 foreign sorghum cultivars and barrenness. The results showed that most traits and barrenness were not significantly correlated, only the number of grain per plant, plant height and barrenness were significantly correlated. Path analysis showed that plant height had the most direct effect on barrenness, followed by 1000-grain weight and primary branch number. The choice of plant height, 1000-grain weight, primary branch number can effectively improve the selection of barrenness of varieties.
