本文研究苎麻主要性状间的相关性及其通径系数,并剖析产生性状相关的原因及估测各性状的相对重要性.为选配亲本、性状选择、提高育种效率及改进栽培措施提供一些依据。材料与方法所选用的8个参试品种均系2龄麻的宿根(鸡骨白、细叶绿、珙县圆麻、江西新余麻、荣昌苎麻、黄壳早、湘苎一号、天柱圆麻)。4行区、每品种设置4个取样点,每取样点随机取样10蔸,测定7个主要性状,共测定280蔸。性状测定值均以取样点的平均数为单位进行统计分析。参照马育华、井山审也和俞世蓉等所述方法估算表型、遗传型和环境的相关系数、直接通径
In this paper, we studied the correlation and path coefficient between the main characters of ramie and analyzed the reasons that caused the traits and estimated the relative importance of the traits, which provided some basis for selecting the parents, trait selection, improving the breeding efficiency and improving the cultivation measures . Materials and Methods The 8 tested varieties were all perennial roots (chicken bone white, fine leaf green, Shexian Yuma, Jiangxi Xinyu Ma, Rongchang ramie, Huang Xianzao, Xiangzhu 1, Tianzhu Round hemp). Line 4, each sample set four sampling points, each sampling point random sampling 10 蔸, measured seven major traits, a total of 280 测 measured. Traits measured values ?? are the average number of sampling points for statistical analysis. With reference to Ma Yuhua, Iguchi Yamauchi and Yu Shirong and other methods to estimate the phenotypic, genetic and environmental correlation coefficient, direct path
