苎麻新品种中苎3号的选育

摘要

中苎3号是中国农业科学院麻类研究所从厚皮种S2×玉山麻S2杂交后代中选育出来的早熟苎麻新品种.全国区域试验中,中苎3号原麻产量2800.58 kg/ha,比对照中苎1号增产6.33％,居参试品种第一位;纤维支数2084 Nm/m·g-1,比对照中苎1号高179 Nm/m·g-1,纤维品质优良.中苎3号所有产量构成因素均超过对照,且适应性好,抗倒性强,抗花叶病,中抗根腐线虫病.%Zhongzhu No.3 is a new early maturity ramie variety developed from the progeny of Houpizhong S2 × Yushanma S2 by the Institute of Bast Fiber Crops.The fiber yield of Zhongzhu No.3 was 2800.58 kg/ha,6.33％ higher than the contrast Zhongzhu No.1 and ranked the first in the national trial;the fiber fineness was 2084 Nm,which was 179 Nm higher than the contrast Zhongzhu No.1 in the national trial.All of the economic traits of Zhongzhu No.3 were better than the contrast.Zhongzhu No.3 showed high resistance to lodging and ramie mosaic,medial resistance to root-rot nematodes,and good adaptability in every trail point.
