Abstract: Grain grouting character was studied on eight high grain yield wheat cultivars which popularized in Guanzhong area belong to early,medium and late-maturing.The result showed that:the high grain yield of early-maturing wheat cultivars take much use of nourishment prefloral storage and usage of photoassimilates correspond during grain grouting period,grouting peak is late and the peak value is high,after peak,grouting rate drop quicker than medium-late maturing cultivars,but grouting rate is high remarkably than medium-late maturing cultivars,till about 35 days postfloral.
