Studies on the Response of Isogenic lines of Compact and lax Type to Fertilization and Plant Density in Malting Barley
맥주맥에 있어서 직두형 및 수두형 Isogenic line의 시비량 및 재식밀도에 대한 반응

Abstract
Taiwan land race, Taichung 2 rowed barley #1 was crossed with England cultivar, Deba abed in 1972, and two isogenic lines-lax and compact heads-were made in 1982. So as to three fertilizer and three seeding density levels were treated at Dan-Kook Agricultural College farm located in Cheonan in 1984-1985. Lax head type had longer spike length and rachis than compact type. The traits uninfluenced by different head types were heading time, number of grains per spike, yield and soluble nitrogen content. However, the traits related to malting quality such as 1,000 grain weight, assortment ratio, protein content of grain and malt, malt extract, malt total nitrogen content, Kolbach index and diastatic power were significantly affected by head types. The number of spikes per m2, yield, assortment ratio, crude protein content of grain and malt yield ratio, extract yield ratio, malt total nitrogen, souble nitrogen content, Kolbach index and diastatic power were affected by fertilizer and seeding density levels in both isogenic lines. The malting quality was best at 12-12-9 kg/l0a fertilizer level and the yield was greatest at 15-12-9 kg/l0a level. Narrow-spaced or drilling seeding had greater yield and better malting quality than conventional row seeding. The plant with lax head type had some advantages in malting quality, suggesting that this trait would be considered as an selection criterion fer good malting quality lines.
