由吉林省生物研究所主持的农业部“七五”计划重点项目“四个羊草新品系的育种”。7月9日在吉林自城市通过了田间验收。羊草是我国东北及内蒙东部草旬草原的重要野生资源,是一种抗逆性颇强的野生优良禾本科牧草。在当前草原改良中,已成为各地大面积种植的一种主要牧草。但现有的野生羊草,由于结实率,产草量,发芽率均很低,已构成了羊草种植生产上的一大难点。由吉林省生物研究所主持在吉林、内蒙、黑龙江八个试区点的支持协作下,采用了生物技术与常规育种技术相结合的方法,从羊草物种分化研究入手,搞清羊
The key project of the “Seventh Five-year Plan” sponsored by Jilin Provincial Institute of Biology is “Breeding of Four New Leymus Chinensis Lines”. July 9 in Jilin from the city passed the field acceptance. Leymus chinensis is an important wild resource of grassland in the northeast of China and Eastern Inner Mongolia, and is a kind of wild and good gramineous pasture with strong resistance. In the current improvement of grasslands, it has become a major pasture planted over large areas. However, the existing wild Leymus chinensis has a very difficult production in the production of Leymus chinensis due to its low seed setting rate, grass yield and germination rate. Under the support of Jilin Provincial Institute of Biology under the support of eight pilot sites in Jilin, Inner Mongolia and Heilongjiang, biotechnology was used in combination with conventional breeding techniques to study the species differentiation of Leymus chinensis,
