苎麻新品种“华苎3号”选育研究

STUDIES ON BREEDING OF NEW VARIETY “HUA ZHU 3”FOR ARMIE

“华苎３ 号”是在新余麻与稀节巴杂交后代中选育出来的新品种。该品种产量高，在品系比较试验中比对照细叶绿增产２１ ．４４ ％ ，在区域试验中与高产对照品种华苎２ 号产量相当；纤维品质优良， 年均纤维细度在２１００ 支以上， 且三季麻的纤维细度均达１８００ 支以上，在品系比较试验中头， 二、三麻的纤维细度分别为２６２７ 、１９８８ 、２１７５ 支，年均２２６３ 支。在区域试验中，头、二、三麻的纤维细度分别为２４９２ 、１９８４ 和１９４４ 支，平均２１４０ ；抗逆性强，对炭疽病亚免疫， 不感染花叶病， 抗旱耐渍，抗风性中等。

Huz Zhu 3”(HZ3), a newly released ramie variety in March 1999,was developed by intervarietal hybridization between “Xinyuma” and “Xijieba” as the male parent. The fibre yield was 21.44% higher than that of the check “Hubei Xiyelu” in the varietal yeeld test and had unsignificant difference in the provincial regional test to the check ——“Hua Zhu 2”(HZ2) that was high yield. HZ3 was high fibre qunlity.Its fibre counts of the lst, 2nd,3th crop,annual mean were 2627,1988,2175,2263 respectively in the varietal yield test;2492,1984,1944 and 2140 respectively in the provincial regional test.It approched immune to anthracnose disease (the disease index was only 0.42) and was not infected by mosaic.It was risistant to waterlogging and drought.
