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 Tankook Agricultural Coll. farm located in Chonan 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.
