摘要
以2012年国家谷子品种区域试验东北春谷区中晚熟组品种的性状结果为数据材料,对东北春谷区中晚熟组谷子产量构成的主要农艺性状进行相关和通径分析。结果表明:穗粒重、单穗重和亩穗数是构成东北春谷区中晚熟组谷子单株产量的主要因素,其次是出苗-抽穗天数、生育期、株高、穗长和出谷率。各性状对单株产量的直接贡献顺序为穗粒重>千粒重>亩穗数>单穗重>出苗-抽穗天数>穗长>生育期>抽穗-成熟天数>出谷率。
The correlation analysis and path analysis on major agronomic traits related to yield of middle and late mature group of the national regional test in spring millet area of Northeast China in 2012 were carried out.The results showed that the grain weight per ear、single ear weight and Mu ear number were the main factors related to yield per plant,then the emergence- heading、growth period、plant height and grain rate.The direct contribution of agronomic traits to yield was in the following order;grain weight per ear 1000- grain weight〉 Mu ear number 〉single ear weight〉 emergence- heading〉 ear length〉 growth period 〉heading- maturity 〉grain rate.
