摘要
"川苎11"(原代号川杂9832)是我所用自育的优良雄不育系"C9451"和优良恢复系"R79-20"配制而成的两系杂交苎麻品种。在2002-2004年四川省苎麻区域试验中平均原麻产量2323.5kg/hm2,较对照川苎4号增产25.8%,平均单纤维细度1934m/g。在组合比较试验中平均原麻产量2000kg/hm2,较对照川苎4号增产41.03%,平均单纤维细度1979.1m/g。生产试验中平均原麻产量2629.95g/hm2,较对照川苎4号增产24.3%。经四川省纤维检验检测局测定,川杂9832平均单纤维细度2174 m/g,纤维强力40.89cN。该品种采用种子繁殖,植株整齐、均匀、高大、粗状、经济性状优良,蔸型、株型理想,高抗苎麻花叶病毒病和苎麻炭疽病,抗旱、抗风力强。
9832 is a new two-line hybrid ramie variety developed by good male sterile line C9451 and restorer line R79-20 in Dazhou Agricultural Research Institute. The average fiber yield of 9832 was 2323.5kg/hm2, 25.8% higher than that of control "Chuanzhu 4"and 2000kg/hm2, 41.03% higher than that of the control "Chuanzhu 4" in ramie regional test and combination yield test in Siehuan respectively. 9832 has high fiber quality. Its fiber counts were 1934 and 2174 in the regional test and shower yield test. 9832 has many features of large plant, thick stem, good economic characters and high resistance to ramie mosaic and anthracnose.
