영문 초록

The objective of this study was to compare yearly variations of heritability, phenotypic, genotypic and environmetal corrlations for eight characteristics of malting barley, and to provide a useful selection information for improving malting barley. Heritabilities of culm length, spike length and number of spikes per ㎡ were very high, but the yearly variations were not large. 1,000 grains weight, number of grains per spike and grain yield were comparatively high in heritability and the yearly variations were slightly large. The genetic correlation coefficients between culm length and spike length, number of spikes per ㎡, number of grains per spike, 1,000 grains weight, and grain yield were positive, and the yearly variations were not large. In the pathway coefficients of the characteristics, the number of spikes per ㎡, 1,000 grains weight and number of grains per spike effected directly to the grain yield.
