长果黄麻新品种‘Y007-10’选育研究

Breeding of Corchorus Olitorius New Variety ‘Y007-10'

经过近10年的精心研究，选育出优良长果黄麻新品系‘Y007—10’。该品系在2009-2010年品系比较中纤维产量居6个参试品种首位，2年纤维产量平均为3667．1kg／hm^2，比对照湘黄麻3号增产14．53％．品系之间差异达到极显著水平。在2011-2012年8地16个点次区域试验中有11点次纤维产量居参试品种第1位．平均纤维产量为3463．66kg／hm^2，比长果对照宽叶长果（纤维产量2897．19kg／hm^2）增产19．55％；比第l对照圆对照果品种179增产18．86％，相比其它所有参试品种增产均达极显著水平；其纤维支数398公支．纤维强力280N，均优于对照品种；中抗小黑点炭疽病．在大田种植一般不发病或少见病斑。

By crossing and then back crossing with compact type 0-4（ I ） and Xiang No.3, the Institute of Bast Fiber Crops of Chinese Academy of Agriculture Sciences obtained one elite offspring. We selected and identified the offspring strains in Hunan and Hainan from 2003 to 2007, the stabilized high yield strain Y007-10 was eventually obtained. By means of comparing plant type and strain feature, we found that Y007-10 grow fast and produced more fiber. The fiber yield of this strain was in the first place in the variety comparison trial which contained 6 strains in 2009~2010. The average fiber yield of Y007-10 attained 3 667 kg/ha., 19.55% higher than that of CK, which far ahead that of other participants. The fiber yield 18.86% higher than that of Corchorus Capsularis L ＂179＂ . Y007-10 fiber count was 398.The fiber strength was 280N. Y007-10 has moderate resistance to carbon myiasis small black spots, planted in field won＇t been affected by carbon maggots.
