This experiment was conducted to breed the Boxthorn varieties with resistance to Anthracnose, good quality and high yielding potential in 1984 to 1986(3 years).The character of Yu seong 1 with resistance to Anthracnose and Yu seong 2 with good quality and high yielding potential are fellows;1, The plant type of Yu seong 1 was semi-elect type but became to electtype after 60C rediation and yield was decreased because of the number of flowers.2. The yield of Yu seong 2 was the highest of all varieties.3. The quality(Extract and Betain contents) of Yu seong 2 was the best ofall varieties and visible character was good.The results of this experinent showed that Yu seong 1 should be promisinglines in south area because of resistance Anthracnose and Yu seong 2 should bepromising lines in north area.hracnose and Yu seong 2 should bepromising lines in north area.orth area.
