AbstractInorder todeeplyunderstand thecharacteristicsof yield formationanddrymatter transportof wheat varieties in Shandong Province during the 195Os-2010s，8 wheat varieties were selected forfield tests，including Bima No.1，JinanNo.2，TaishanNo.1，LumaiNo.1Yannong19，Jimai22，Tanmai98，andLuyuan502.Theyieldandits components，dry matter translocation characteristics，and changes indry mater allcation among diffrent organs of these varieties werecomparativelyanalyzed.Theresults indicated that with variety improvement，wheatyield，grains per spike，and thousand-kernel weightshowedanincreasing trend，whilethenumberof spikesremained relatively stable. The contributionrate of pre-anthesis dry mater storageandtranslocation to grain decreased，while thecontribution rate of post-anthesis drymatteraccumulationgradually increased.Theproportionofdrymatter allocated to leavesand spikes increased，whilethat allocated tostems decreased，indicating enhanced sink capacityandsource strength in wheat.Coordinating yield components，promoting there-translocation of pre-anthesis stored substances basedon ensuring post-anthesis dry mater accumulation，and optimizing source-sink structure were identifiedas important objectives for future high yield wheatbreeding.
