Abstract
“Cheongwoo”, a white winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross “Kanto75/8/Tapdong/4/Bb#1/Jangkwang// STRAMCHO/3/Suwon220/5/Suwon185/ CI12703//Kanto75///Suwon219/7/F1277” and “Keumkang” in 1998 at RDA. “Keumkang” is a semi-hard white winter wheat with high yield. And mother plant is a winter wheat with long culm length, high yield. “Cheongwoo” was evaluated as “Iksan326” in Advanced Yield Trial Test in 2007. It was tested in the regional yield trial test between 2008 and 2009. “Cheongwoo” is first whole crop wheat with long culm length, high-yield. The Heading date of “Cheongwoo” was similar to “Keumkang”. The average forage yield of “Cheongwoo” was about 14.8 ton ha-1 in dry matter in paddy field. This dry matter was higher than dry matter of “Keumkang” (13.2 ton ha-1). The cultivar had 97 cm of culm length, 1,070 spikes per m2 and it showed better rate of culm. Culm length of “Cheongwoo” were longer than “Keumkang”. This cultivar would be suitable for the area above the daily minimum temperature of -10°C in January in Korean peninsula. Our research will improve good-quality of silage by using winter cereal crops.
