通过对人参主要经济性状的相关和通径分析、遗传力及综合选择等研究，从理论上阐明丰产人参品种选育应以单根重为主，根粗与根长协调搭配为副。建立了单根重＋根粗＋茎粗的综合选择指数方程。对在上述选育理论指导下入选的４个人参品系进行了多性状综合评价，经过产量比较试验和区域试验选择了丰产性强、单根重大、根形美观、皂甙含量高的品系，育成了人参新品种吉参１号。
Through the research on correlation and path analysis of major economic traits of ginseng, heritability and comprehensive selection, it is theoretically demonstrated that the selection of high yield ginseng varieties should be based on single root weight, and the combination of root diameter and root length should be the vice. The comprehensive selection index equation of single root weight + root thickness + stem diameter was established. A total of 4 ginseng lines selected under the guidance of the above selection theory were evaluated comprehensively by multiple traits. After selecting the lines with high yield, large single root, beautiful root shape and high saponin content through yield comparison test and regional experiment, Ginseng new varieties of ginseng 1.
