湘北丘陵区旱地苎麻品种筛选研究

摘要

An agronomic traits analysis to 11 ramie germplasms and one contrast resource which grow in the hilly region of north Hunan, during 2005～2007, has been explained in this article.After a field plot experiment work on 7 generations of ramie in 3 years, we got a result.The result shows that there are four pieces of ramie perform obviously higher yield than ClasK, The yield ofZhongzhu 1 was 7788 kg/hm2, Polyploid 1 5 313 kg/hm2, Xiangzhu X5 5 313 kg/hm2.and Xiangzhu X3 was 5 254.5 kg/hm2.Finally Zhongzhu 1 and Polyploid 1 were considered as the high-yield germplasms which are suitable for planting in hilly region.%2005～2007年在湘北丘陵区旱地对11份苎麻种质和1份对照种质进行农艺性状分析和评价.通过3年7季麻的小区试验,结果表明:供试的11份苎麻种质中,中苎1号(7788 kg/hm2)、多倍体1号(6770.55 kg,hm2)、湘苎X5(5313 kg/hm2)、湘苎x3(5254.5 kg/hm2)的产最明显高于湘苎2号(CK).最后筛选出适合丘陵区利种植的高产种质为中苎1号和多倍体1号.
