摘要

ZHONGZHUMA No.2 was bred by Institute of Bast Fiber Crops ,Chinese Acad-emy of Agricultural Sciences with mutation breeding method. The regional tests were carried out in two years in Yunnan province. The results showed that :The stem yield was 10669.5 kg/hm2 , being the same as the CK. The fiber ratio was 30.4% ,being 1.24 percentage points over the CK. The fiber yield was 2675.2 kg/hm2 ,being 10.56% over the CK. And also it was No.1 a-mong all the tested new lines and varieties. The seeds yield was 879.9 kg/hm2 ,being 5.09% o-ver the CK. The test results was identified by seed management office of Yunnan province ,and it was named as ZHONGZHUYAMA No.2 ,and was expanded to be planted in Yunnan province.%中亚麻2号是中国农业科学院麻类研究所采用诱变以及系统选育的方法育成。该品种在云南两年区域试验原茎产量10669.5kg／hm2，与对照相仿。出麻率为30.4％，比对照高1.24个百分点。纤维产量2675.2kg／hm2，比对照品种增产10.56％，在参试材料中位列第一位。种子产量可达879.9kg／hm2，比对照增产5.09％。2013年通过云南省种子管理站组织的品种鉴定，命名为“中亚麻2号”，并正式推广。
