摘　　要：对10份苎麻优质种质和2份对照种质的农艺性状和纤维细度进行了鉴定评价。结果表明,所选材料的农艺性状和品质性状均存在丰富的变异;供试10份优质种质的纤维细度明显高于两对照,而产量却明显低于两对照,其中,安龙苎麻1号的纤维细度达2 038m.g-1,产量达到1 762.71 kg.hm-2,丰产性较好;新民家麻、定业苎麻、龙塘白麻、安龙苎麻2号、奉节梅子线麻、那为苎麻1号产量较低(>1 050 kg.hm-2),品质较好(纤维细度>2 100 m.g-1),其他3份优质种质的纤维细度均大于2 200 m.g-1,但产量低(产量≤1 050 kg·hm-2)。Agronomic and bast fiber quality characters of 12 accessions of ramie including 10 high fineness accessions and 2 controls were evaluated. The results showed that there was significantly variance among agronomical characters, The average fiber fineness of 10 accessions was higher than controls, but lower in average yield. The yield of An-long-zhu-ma No.1 was very high, and its fiber fineness was 2 038 m·g^-1. There was lower-yield, good fibre fineness in some accessions, such as Xin-min-jia-ma, Ding-ye-zhu-ma, Longt-ang-bai-ma, An-long-zhu-ma No.2,Feng-jie-mei-zi-xian-ma, Na-wei-zhu-ma No.l. The fibre fineness of the others was above 2 200 m·g^-1, but the yield was lower.
