采用航天诱变技术，对C90-2辐照后代优异单株进行3年6代的定向筛选、纯化，2007年获得稳定优异的株系C2005-43，2008年至2010连续进行品系比较，纤维产量三年平均3784.00 kg/hm2，比对照增产10.5％以上，达极显著水平。2年8点区域试验，纤维产量增产8％以上。 C2005-43纤维支数408支，纤维强力299 N。综合性状表明，该品种在纤维品质、高产性、稳产性、黄麻炭疽病抗性方面表现优良。%With the space mutation technology , irradiated offsprings C90-2 were screened direc-tionally and purified for 3 years ( 6 generations ) , a stable excellent strain C 2005-43 was obtained in 2007.Continuous strain comparison was conducted from 2008 to 2010 , the average fiber yield of three years was 3784.00 kg/hm2 , 10.5%higher than the control , reached extremely significant level.Fiber yield of C2005-43 increased more than 8%according to eight locations test in two years.Fiber number and fiber strength reached 408 m/g and 299 N respectively.Comprehensive traits showed that this variety performed well in fiber quality , yield, stability and anthracnose resistance.
