Ordered population could augment panicle angle and panicle length,which fa-vored the formation of large panicle,erect panicle variety was more fit out-of-order cultivation than bending panicle variety.Distributing mode had significant influence on yield and biologi-cal yield,yield is higher in ordered population than that in out-of-order population.
