양적형질을 중심으로 다변량 해석법에 의해 택사 품종들간의 유연 관계를 추정하고 이에 기초한 cluster analysis를 실시하여 품종을 분류한 결과는 다음과 같다. Euclidian distance (D2)에 의하여 공시한 62개 품종을 5개군으로 대별해 볼 수 있었는데 제1군이 12품종, 제2군이 21품종, 제3군이 17품종, 제4군이 5품종, 제5군이 7품종으로 군을 형성하였다. 제 1군은 건근중은 높고, 생근중이 낮으며 제2군은 생근중이 높고 제4군은 건근중이 낮은 품종군이었다. 지리적 분포와 유전적 변이는 직접적인 관련이 없었다. 품종군내, 품종군간의 D2에 가장 크게 영향을 미친 형질은 경장과 생근중이었다.

Followings are resulted through the analysis of the maln characters and the leaf ingredients, which is on the purpose of getting the basic materials to improve jaso and increase its production.Of the introduced varieties, Jukyeubjaso-stem length is 180cm, ear length is 37cm, No. of branches ofstem is 27, leaf length Is 16cm, leaf width Is 15cm-has better character than any other. Gurye local-stem length is 179cm, ear length is 38cm-is taken to be the best in the Geo-ecotypic.In the yield of leaf and seed, JukyeubJaso Is 727kg/10a, the greatest of all. In the leaf softness, allthe Inirorluced varieties are about 3.5 degrees, the Geo-ecotypic, about 2. The qualify of the introducedvat'ieties is better· than that of the Geo-ecotypic. Estimating on the chemical analysis of leaf,Jukyeubjaso has Protein 21.84%, Total carbohydrate 7.91%, Fe 126ppm, and Gurye lacal has Protein21.7 a, Total carbohydrate 8.4%, Fe 148ppm, expressing the highest. In correlation coefficients of leafchemical components, between protein and Total carbohydrate, Protein and Mn, protein and Fe, Pro-tein and Cu all the sorts show the positive correlation. Among them the Geo-ccoyplcs show the hlghestsignificance.
