摘要
目的:运用单株选育法,对目标太子参单株进行株系比较试验,为太子参新品种的选育提供种质材料。方法:以施秉SB-4号种源的8个太子参单株为选育对象,观测植株的27个表型性状、8个产量性状,UV分光光度计检测各株系的多糖含量。对观测结果运用因子分析法进行比较和筛选,单因素方差分析对其药材中多糖含量进行评价。结果:因子分析将27个表型性状归属于7个主因子,其中ZT-01,ZT-02,ZT-06,ZT-07株系的综合表型性状较好;8个产量性状可简化为新的3个主因子,以ZT-01,ZT-02,ZT-03,ZT-07株系的综合产量性状较好;单因素方差分析显示,ZT-01,ZT-02,ZT-05,ZT-08株系的多糖含量显著高于ZT-03,ZT-04,ZT-06,ZT-07株系。结论:从表型性状,产量性状和品质性状综合考虑,ZT-01,ZT-02,ZT-03,ZT-06,ZT-07表现优良,其中ZT-01,ZT-02株系可作为重点扩繁株系进一步选育;ZT-06,ZT-07株系的株型,主茎节数等表型性状好,可以作为观赏品种选育;ZT-03株系的抗性好,产量高,可以作为抗性品种进行选育研究;ZT-05株系的多糖含量高,翌年继续进行单株筛选。
Objective： To provide new germplasm materials for breeding new varieties of Pseudostellaria heterophylla. Method： The method of single plant selection was adopted, with the comparative experiments being carried out under the same conditions in Shibing county. The 8 plants of Shibing SB-4 were compared respectively with factor analysis for 27 phenotypic traits and 8 yield traits, and single factor variance analysis for the contents of polysaecharides. Result： Using factor analysis, 27 phenotypic traits were classified into 7 principal divisors and 8 yield traits were simplified into 3 principal divisors. The 4 strains of P. heterophylla, ZT-O1, ZT- 02, ZT-06 and ZT-07, performed better than others in the phenotypic traits, and ZT-01, ZT-02, ZT-03 and ZT-07 in the yield traits. The contents of polysaccharides of ZT-01, ZT-02, ZT-05 and ZT-08 showed significantly higher value. Conclusion： There is significant difference among the 8 strains of P. heterophylla in phenotypic traits, yield traits and quality traits, making it possible to select certain strains for different purposes. ZT-01 and ZT-02 can be breaded further. ZT-06 and ZT-07 were used as ornamental cultivars for its great phenotypic traits. ZT-03 with good resistance and high yield was taken as resistant variety, and ZT-05 would face next selection on the basis of its high content of polysaccharide.
