Selective Breeding of New Forage Ramie Variety Minsizhu No.1

The ramie resources (Pinghe ramie) which possessed the characteristics of high yield, strong regeneration, drought resistance, wide adaptability, used cobalt 60 γ to obtain new lines of forage ramie. After seedling planting, excellent mutant screening and variety test, it finally was bred of Pinghe ramie-2 of a high yield, good resistance, high protein content, which officially named as Minsizhu No.1 in 2012. The average annual fresh and dry grass yield were up to 138.8 t·hm^-2 and 28.0 t·hm^-2 respectively in 2 years and 5 points regional test, increasing 32.15% and 37.08% above Zhongsizhu No.1, the difference reached extremely significant level; The average annual yield of fresh and dry yield of Minsizhu No.1 respectively were up to 140.7 t·hm^-2 and 24.7 t·hm^-2 in two years productive tests, than control increasing 18.9% and 17.32%, the difference reached extremely significant level.
