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 necessary which could be used for breeding better quality and high yielding whole crop silage barley. The parents, F₁ and F₂’s of cross line between wide outer glume variety Triple bearded dumb mariout(C.I. 2523) and 4 narrow outer glume varieties were studies in field experiment at experiment farm, Dankook univ., Cheonan city, during 1990~1991 crop season. The results are summarized as follows: Broad sense heritabilities of crude protein, crude oil, crude fiber and ash content were high and its were expected to high efficiency of selection for feed compositions in the early segregating population. The nutrient compositions such as crude protein, crude fat, fiber, ash and soon showed normal distribution as well as transgressive segregation among F₂ population, so could select a high nutrient plant. The gene of wide outer glume of barley showed pleiotropic effects that its made crude protein, crude oil and ash content increase. The gene of wide outer glume of barley could be used as marker gene for breeding better quality, a high yielding whole crop silage barley.
