摘要: 用红麻(Hibiscus cannabinus)722(♀,2N=36+32+4SAt)与金钱吊芙蓉(Hibiscus raidatus)(♂,2N=72=70+2SAt)进行种间杂交,杂种F12N=54=51+3SAt,并育成86-369(F142N=36=30+6SAt).1987-1992年在全国与青皮三号28点次的对比,平均每公顷产原麻5353.5k8,增产17.02%,达极显着水平。与红麻722计22点次的对比,平均每公顷产原麻4918.5kg,增产16.9%也达极显着。86-369的花瓣淡紫蓝色,经济性状优良,抗病力强于青皮三号。1991~1992年在安徽省进行生产示范表现较好,受到麻农欢迎。Abstract: Kenaf (Hibiscus cannabinus)722(♀,2N=36=32+4SAt,Whole lamina.Yellow flower petals) and Cottonrose Hibiscus(Hibiscus raidatus)(♂,2N=72=70+2SAt.Crack lamina.Purple-red flower petals)were used to inter species cross.F1,was 2N=54=51+3SAt.Crack Lamina.Purple-red (lower petals.Hybrid progeny was selected and bred to cottonrose hibiscus kenaf 86-369 (F14 )(2N=36=30-6SAt).It was compared with Qingpi No.3 through 28 placetimes in all over the coutry during 1987-1992.The average of dry bark weight was 5353.5 kg/hm2 increased by 17.02% with qingpi No.3 at the 1%significant level.Also it was compared with kenaf 722 through 22 place-times,the average of dry bark weight was 4918.5 kg/hm2, increased by 16.9% at the 1% significant level either.Flower petals of Cottonrose hibiscus kenaf 86-369 were pale blue, palmatipartite leaves.Economic Characters are better than those of Qingpi No.3.fiber quality is good.disease resistance is better than that of Qingpi No.3.Production demonstration in Anhuei province showed good result,it was welcome by farmers of bast fiber production.
