영문 초록

The genetic segregation of awn-brittleness (da2) and awn characteristics of a barley variety Milyang 55 were exammined. Awn of Milyang 55 shattered at 35~40 days after heading in the field. Its culm length was 85㎝ and head length was 3.2㎝. Heading date of this variety was April 23 and maturing date was May 30. Among yield components, number of spikes per ㎡ was 606, number of grains per spike was 52, and 1,000-grain weight was 31.9g. Grain yield per 10a was 268㎏ with lodging resistance. All F₁ plants of Milyang 55/Alchanbori showed normal awn. But F₂ progenies of this cross were segregated with the ratio of 13(normal) : 3(brittleness). This suggested that the inhibiting factor acts on the expression of awn-brittleness. In the cross of Milyang 55 and Milyang 6, the same genetic pattern also recognized. Milyang 55 and its progenies have very good agronomic characteristics, especially grain shape with awn-brittleness.
