| Abstract: | On the basis of numerical taxnomy of germplasm resources of Cucumis melo L. , The grades classification functions were set up for three sup-species and four varieties of Cucumis melo L. by step-wise discriminant analysis with 98 characters,which stands a fundement for auto-identification of germplasm resources of Cucumis melo L.. The first grade classification function being made of the number of fruit per plant, the shape of hair top on stem, the thickness of skin and suberization of skin has 97.5% correct rate on distinguishing the three sup-species. The second grade classification function depending upon the character of distance of two cotyledon top, the grade of diseases, the length of sepal of complete flower, have/no of cicatrice of flower on fruit and the number of nodes of second branch per plant has 90% correct rate on discriminating netted melon and non-netted melon; the second classification function including characters of the sour of sarcocarp, bursa of seed, parthenocarpy, the number of stamens of complete flower and the diameter of friut distinguishing oriental melon and oriental pickling melon at 100% correct.
In addition, the value and the limit of discriminant analysis used in germplasm study were discussed. |
