| 摘 要： | “川苎8号”(原代号D-156)是我所用自育的优良雄不育系C26和恢复系B8配制而成的两系杂交苎麻组合。在1995—1997年四川省苎麻区域试验中平均原麻产量1957．8kg／hm^2,较对照红皮小麻增产41．85％,在组合比较试验中平均原麻产量2546．1kg／hm^2,较对照红皮小麻增产69．04％;两组试验增产均达极显著水平。该组合纤维品质优良,在苎麻区域试验中平均单纤维细度为1913支;在生产示范中,经达州市纤检局检测平均单纤维细度为1978支。该组合采用种子繁殖,后代在品质和经济性状上分离变异极小;植株高大、粗壮、经济性状优良,蔸型、株型理想,抗逆性强,高抗苎麻花叶病,抗旱、抗风力强。

| Abstract: | D - 156 is a new combination in two -line hybrid ramie developed by male sterile line C26 and restorer B8 in Dazhou Agricultural Research Institute. The average fiber yield of D - 156 was 1957. 8kg/hnr, 2546. lkg/hm2 and 41. 85%, 69. 04% higher than that of check "Hongpixiaoma" in Sichuan province ramie regional test and combination yield test respectively. D - 156 was of high fiber quality. Its fiber fineness was 1913 in the regional test. Different from traditional young shoot or root multiplication, the multiplication of this combimation is seed. Little variation was observed on yield, quality and economic characters of offsprings. D - 156 has many features of large plant, thick stem, good economic characters and high RMD resistance. |
