本文研究了90份长果种黄麻资源性状鉴定资料。通过对这些品种主要性状表现及其相互关系的分析,以产量影响因子直接贡献大小构成判别方程对综合性状的优劣进行判断。以单株生产力和综合判别指标对鉴定长果种资源进行筛选,筛选出9份单株生产力高,综合性状好的高产种质依次是:89—7(404029)、湘黄麻1号、耳朵叶、宽叶长果、巴麻72—3、浙麻2号、长果134,巴麻73—1和台南红皮,其单株生产力平均值15.12g,较全部资源品种(?)=9.88高5.14g,平均高出51.52%。
This paper studied the identification of 90 characters of jute germplasm resources. Through the analysis of the main traits and their interrelationships of these cultivars, the direct contribution of yield factors is used to form discriminant equations to judge the merits of the comprehensive traits. Nine high-yielding germplasms with high productivity and good comprehensive characters were screened by single plant productivity and comprehensive discriminant index. Nine high-yielding germplasm with good comprehensive characters were selected as follows: 89-7 (404029), Xiangjutemai No.1, ear leaf , Broad-leafed fruit, 72- 72g of barley, 2 of Zhejiang hemp, 134 of longan, 73-1 of barley and red skin of Tainan, the average productivity per plant was 15.12g, which was 9.88 higher than that of all varieties (?) 5.14g, an average of 51.52% higher.
