摘　　要：2003～2004年在长春对6个春小麦品种的6个性状进行了对比试验。结果表明,小麦的抽穗期和穗粒数均对产量产生了正效应。而成熟期、千粒重和植株高度则在不同的年度中对产量的效应表现各异。因此,在长春地区选育小麦品种时应适当延长抽穗期、调节植株高度和成熟期,以达增加千粒重和穗粒数的目的。Six varieties of wheat were selected and 6 agronomic characteristics were analyzed in 2003 and 2004. The results indicated that days to ear and grain numbers were positively correlated with yield. Days to mature, weight of 1000 grains and plant height have different effect in different years. So we can presume that day to ear is an important factor for selecting wheat varieties in Changchun areas.
