Two lines mat rush, Fs-73-I-8031 and Fs-72-P-8006, were introduced from Japan in 1973 and 1972, respectively, and were cultured acclimatized and selected TARI and other regions. The performance of the two lines has been outstanding in comparative trials, integrated cultural demonstration and the new-line demomstration. The straw yields per hectare of the two lines were 28.9% and 56.2%, respectively, higher than that of Kan-san No. 3, served as the check variety, The ratios of first-grade grass to total straw yield of the two lines were 179% and 13.7%, respectively, higher than that of the check variety. Both the two lines also showed a shorter tip-rot than the check variety. On account of the high yielding and the superior agronomic performance, the two lines were registered as Tainung selections No. 1 and No. 2, respectively, in 1980.
