摘  要:
本研究应用DUS测试对19个国内外鸭茅品种进行研究,为筛选适合我国南方地区种植的多年生优质牧草及南方现代草地畜牧业发展做出贡献。结果表明,供试鸭茅品种可分为早熟、中熟、晚熟3种类型;且生长速度、鲜草产量、鲜干比、分蘖数、抗性表现差异明显,通过差异比较可有效区分供试鸭茅,通过品种综合排序,最终筛选出适合作为鸭茅杂交亲本的优良育种亲本。

摘  要:
In this report,DUS testing were used in 19 Dactylis glomerata L.varieties worldwide,for screening excellent perennial grass for the southern China regions and the development of southern grass-livestock husbandry.The results showed that,the D.glomerata varieties could been divided into early,middle and late-maturing 3 types,and there were obvious differences among D.glomerata on growth speed,green-grass yield,green-hay ratio,tiller numbers and resistance,which presented the differences of studies D.glomerata,there were a comprehensive ranking about the DUS testing screening,and selected excellent D.glomerata varieties for the cross of breeding in the end.
