Abstract
Kenaf new variety KB2,green stem,divided leaf,which was bred from progeny of “EV41X72—44”,is the most promising variety among the breeding lines at present.The average fiber yield of KB2 was 303.8kg/666.7m2,22.4%， higher than that of CK“7804”in Hunan Provincial Kenaf regional trial at 5 locations for 2 years,248.6kg/666.7m2,15.8% higher than that of new CK“74-3”in national kenaf regional trial at 8 locations in succesive 2 years(1997-1998),253.9kg/666.7m2,21.2% higher than that of Qingpi 3 in Anhui Province regional trial in 1996-1997.Average dry stalk yield of KB2 was 1.22T/666.7m2,25.4% higher than that of Qingpi 3.Average fiber and stem yields of KB2 ranked the first among the new strains and standard varieties.Its average fiber strength was 43.8kg/g,fineness 276.8m/g.The average length of bark fiber 2.74mm,core fiber 0.76mm,ratio of bark to stalk 38.1%,ratio of pulp to dry stalk 48.1% with the method of sulfate cook.All of the traits were better than that of CK.The main abvantages of KB2 were more effective plants at final harvest,no early flowering,large plants,superior fiber quality,high resistance to anthracnose disease and wide adaptability.关键词
