【摘要】 中红麻12号(原名"SCS11-04")系利用国外优良红麻种质(EV71×非洲红麻)F1与国内抗病特异育种材料SCS1复合杂交选育而成的一个集高产、抗病、抗倒、优质、适应性广于一体的纺织、造纸用的红麻优良新品种,红茎、裂叶型、不早花。在1999-2000年全国红麻主产区的六省七点全国红麻区试中,平均纤维产量3565.5kg/hm2,比对照红引135平均增产17.9%,在新品系中居首位,在生产试验中较对照极显著增产,干茎产量19009.5/hm2,较对照增产18.6%,表现出植株高大,皮较厚,有效株数多,干茎产量和出麻率均高,抗病性强,纤维品质好。纤维品质经农业部麻类产品质量监督检验测试中心检测,纤维支数270支,强力482牛顿,符合纺织要求。采用硫酸盐法制浆,SCS11-04的平均干茎纸浆得率为47.3%,高于对照。人工接菌炭疽病鉴定,病情指数为31.9,烂头率为7.9%,属于高抗类型。并于2006年已通过全国农作物品种鉴定。更多还原

【Abstract】 Kenaf new variety China Kenaf 12,red stem,divided leaf,which was bred from progenies of "EV71×African Kenaf",is the most promising variety among the breeding lines at present.The average fiber yield was 3565.5kg/hm2,17.9% higher than that of CK "Hongying135" in 6-province,7-location kenaf regional trial in 1999-2000.Average dry stalk yield was 19009.5kg/hm2,18.6% higher than that of CK.Average fiber and stem yields ranked the first place among the new strains and standard varieties.Its average fiber strength was 482 N,fineness was 270 m/g.It was high resistant variety with disease index of 31.9,ratio of pulp to dry stalk was 47.3% with the method of sulfate cook.All of the traits were better than those of CK.The main advantages of China Kenaf 12 were more saving time at final harvest,no early flowering,large plants,superior fiber quality,high resistance to the anthracnose disease and wide adaptability,it was released by National Crops Varieties Approval Committee in 2006.更多还原
