영문 초록

A study was carried to get basic information of barley breeding for early and high yielding varieties. In isogenic analysis, early variety was 19-2% lower in grain yield than late one. The grain yield was higher in the maturing type which flower early but mature late, while lower in other maturing type, flower late but mature early. In a tipical maturing type of Korean barley cultivars, which flower early and mature early, number of grains per spike and 1000-grains weight were major factors to increase the grain yield. In the different seeding date, maturing period of early variety was longer than late one. On the while, grain yield and number of spikes per square meter were decreased severely by the delay of seeding date, but number of grains per spikes and 1000-grains weight were not.
