摘　　要：运用SAS统计软件对杂交水稻11个性状进行通径分析。结果表明,单株有效穗、每穗总粒数、每穗秕粒数和千粒重对单株穗重有较显著的直接效应,全生育期、株高、剑叶长度、穗长对单株穗重表现显著的间接效应。rice characters on path analysis were studied by SAS statistic system.The result indicated that panicles/plant,grains/panicle、 non-filled grains/panicle,and 10 0 0 -grain weight had significant direct effecton the yield/plant,while growth duration,plant height,flag leaf length and panicle length had significantindirect effect on the yield/plant.
