为提高谷子育种效率,找出赤峰地区谷子农艺与经济性状对于单株产量影响的重要性排序,应用灰色关联分析方法对赤谷系列谷子单株产量与农艺、经济性状之间的关系进行了研究。结果表明:穗重、草重、千粒重、生育期这四个性状与单株产量最为密切,节数、穗长、穗粗、株高对单株产量影响较小,在育种的性状选择中,应主要考虑穗重、草重、千粒重和生育期,兼顾其他性状。
In order to improve the efficiency of millet breeding and find out the importance of agronomic and economic traits of millet per plant on the yield per plant in Chifeng region, the relationship between yield per plant and agronomic and economic traits of millet was studied using gray relational analysis. The results showed that the four traits such as panicle weight, grass weight, 1000-grain weight, and growth period were the most closely related to the yield per plant. The number of segments, ear length, ear diameter and plant height had little effect on the yield per plant. Should mainly consider the ear weight, grass weight, grain weight and growth period, taking into account other traits.
