摘要
“Ｂ２３２”系由“赣苎１号”的优良单蔸与“家麻”杂交，从其Ｆ１代种子繁殖中选出的优良单蔸培育而成的。经两年区域试验，平均比对照“芦竹青”增产３９．７７％，增产达极显著。大田生产示范推广，平均产量在２２５０ｋｇ／ｈｍ２以上，较对照“芦竹青”增产４３．５０％。单纤维支数高，３年省区试平均为２４７２．６０支，达特优质指标。高抗苎麻花叶病、炭疽病和疫病。该品种以优质、高产、稳产、抗病、抗风、易剥易刮和适应强为其优良特性问世。
B232 is a new ramie variety which was selected from the F 1 generation of seminal propagation via elite single plant of Ganzhu 1 intercrossing with Jiama. Two-year regional tests showed that average yield of B232 increased by 39.77% over that of CK (Luzhuqing), and reached the level of extreme significance. The results of production demonstration and extension in fields indicated that the average yield of B232 reached 2 250kg/hm 2 above, 43.5% over that of CK. In three-year regional tests fiber fineness single averaged 2 472.0 and reached at the extremely superior level. The variety has strong resistance to mosaic, anthracnose and epidemic disease, and has some excellent properities such as superior quality, high and stable yield, disease and wind resistance, easy to peel off and scrape and wide adaptability.
