贵州苎麻种质资源遗传潜势分析

Analysis On Hereditary Latent Superioritvy Of GuiZhou Ramie Germplasm Resources

该文研究了13份贵州苎麻地方品种7个数量性状的遗传变异系数、遗传力和遗传进度，结果显示供试品种部分性状的遗传变异较丰富，预期选择效果较好。遗传相关和通径分析表明，单蔸产量和纤维品质的矛盾主要由鲜皮厚引起，在苎麻丰产优质选择中，以株高、有效株率、鲜皮出麻率相结合间接选择，可望获得理想效果。

In this artical, the hereditary variation coefficient and capacity and velocity of seven quantitative characters of thirteen Guizhou ramie vareties were studied and analysed. The results showed that some characters of tested varieties there are abundant hereditary variation, contridiction between fibre yield per stool and quality mainly are caused by bast thickness. selecting indirectly, there is an ideal effect when combine plant heigth with ratio of effective stoo)l and fresh bast to get stools of good fibre quality and high yield.
