영문 초록

This experiment was carried out to determine the inheritance of wide outer glume, to investigate the associated agronomic characters with wide outer glume and to examine variations of chemical feed composition in barley. This study was conducted to obtain basic genetic informations which could be used for breeding better quality and yielding whole crop silage barley. The parents, F₁ and F₂’s of cross line between wide outer glume variety Triple beared club mariout(C. I. 2523) and 4 narrow outer glume varieties were studies in field at experiment farm, Dankook univ., Cheonan city, during 1990~1991 crop season. The results are summarized as follows : The wide outer glume of barley was a simple recessive and controlled by one set of allele. Broad sense heritabilities of wide outer glume were high and it was expected to high efficiency of selection for wide outer glume in the early segregating population. The gene of wide outer glume of barley showed pleiotropic effects including late heading, shorteninng of culm length, upper internodes, spike and awn length. Especially, it made 1s internode short. There was no significant correlations between wide outer glume and yield of barley, though the gene of wide outer glume decrease number of spike per plant and number of grains per spike. The gene of wide outer glume of barley could be used as marker gene for breeding agromic characters and a high yielding whole crop silage barley and it should also be considered in selection procedure for improving agronomic characters and a high yielding line.
