摘要
中杂红316(原名"H316")系利用外观性状茎色、叶型相似、经济性状互补性强的红麻品系152和P91为亲本,从数十个杂交组合中筛选出的超高产型抗病优质杂优组合H316(F1),在比较试验中,分别比KB2和红引135增产26.1%和56.0%;干茎产量达21348.45kg/hm2,比对照中红麻10号增产16.6%;H316(F1)在2004-2006年全国红麻区域试验中,平均纤维产量4171.31kg/hm2,比对照增产14.18%,增产极显著;在全国红麻生产试验中平均纤维产量4339.5kg/hm2,比对照中红麻10号增产12.56%;主要产量构成因素为株高405.98cm、茎粗1.89cm、纤维鲜皮厚度1.24mm、干皮精洗率60.85%、平均笨麻率11.95%;纤维品质经农业部麻类产品质量监督检验测试中心检测,纤维支数为275m/g,纤维强力为332N,均优于对照;该品种经人工接种炭疽病菌鉴定,烂头率为0.7%、病情指数为10.8,其抗病性指标明显优于对照。表明中杂红H316是高产、优质、多抗、适应性广的纺织、造纸兼用的红麻新组合。
Kenaf hybrid H316, red stem, divided leaf, which was bred and selected from several decades of kenafcrosses, is the most promising hybrid used in production at present. The average fiber yield of H318 was 5460kg/hm2, 26.1% and 56.0% higher than that of CK KB2 and ＂Hongying135＂ respectively in comparison of kenaf hybrids in 2003, 4171.31kg/hm2, 16.6% higher than that of CK ＂China Kenaf 12＂ in national kenafregional trial at 7 locations in 3 years （2004-2006）, the highest among new lines and hybrids. The average dry stalk yield of H316 was 21.35t/hm2, 14.18% higher than that of CK at 3 sites. Its average fiber strength was 332N（ 1 g fiber, length 30cm）, fineness 275n/g. Under the artificial inoculation, the anthracnose disease index was 10.8,the rate of died top stem 0.7%. The main advantages of kenaf hybrid H316 are large plant, more available plants at final harvest, high ratio of bark to stalk, good fiber quality, high resistance to the anthracnose disease and wide adaptability.
