A new kenaf variety-China Kenaf 13 (originally named LC0301) was selected and bred from the progeny of "KB2xKBll", which would be a textile and multipurpose new kenaf variety with high yield, disease and lodging resistances, high quality and wide adaptability. It is no early flowering, red stem and lobed leaf. In national regional trials, the average fiber yield of China Kenaf No. 13 was 4251.31kg/hm2, 16.37% higher than the CK "China Kenaf No.10" which was 3855.2 kg/hm2 from 2004 to 2006. Its average fiber and stem yields ranked the first place among the conventional varieties. In the productive trials its average fiber yield was 4541.61 kg/hm2, 17.8% higher than the CK which was 3855.2 kg/hm2. The main traits that China Kenaf 13 has are high plant, thick bark, high percentage of effective plants, high bast fiber and dry stem yield, disease-resistance and good fiber quality. Its average fiber strength was 316 N, fineness was 267 m/g, all the traits were better than those of CK. The disease index was 12.1 and the root-rotten rate was 0.8%, which could be concluded that this new kenaf variety was high resistance to the anthracnose disease.%中红麻13号(原名"LC0301")系利用优良红麻材料(KB2×KB11)F1与KB11回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、多用途的红麻新品种,不早花、红茎、裂叶型.在2004-2006年全国红麻区域试验中,平均纤维产量4251.31公斤/公项,比对照中红麻10号3653.33公斤/公项增产16.37%,居第二位,在常规品种中居首位.在生产试验中平均纤维产量4541.61公斤/公项,较对照3855.2公斤/公顷增产17.8%.表现出植株高大,皮厚,有效株数多,干茎产量和出麻率均高,抗病性强,纤维品质好.经农业部麻类纤维检测中心检测,纤维支数267支,强力316牛顿,优于对照品种.人工接菌炭疽病鉴定,病情指数为12.1,烂头率为0.8%,属于高抗类型.
