So as to compare the differences of major agronomic traits according to fall plant types, two cultivars and eight lines which were derived from the same pedigree, were planted and analyzed. The heading and mature times, and culum length of erect plant types were earlier or longer, but the spike number per ㎡ and yield were smaller than the those of prostrate types. Also, 1000 grain weith, assortment rate and light penetration rate in erect types were greater than in prostrate types. The heading time was positively correlated with mature time and yield, but negatively correlated with culum length, 1000 grain weight, assortment rate and light penetration rate. Yield was negatively correlated with light penetration rate. If the lines with prostrate types in fall season, fast regrowth after wintering and rapid elongation of stem were bred and selected, it will be of great benefit in the area requiring sever winter hardiness.
