Abstract:
OBJECTIVETo study the morphological variations of Paris polyphylla var. yunnansensis in different population for genetic diversity and breeding.
METHODThe characters of roots, stalks, leave and flowers were observed. The results were analyzed by DPS software.
RESULT AND CONCLUSIONP. polyphylla var. yunnansensis showed plenty genetic diversity, there existed obvious differences in morphological characters of different population. Principal components analysis showed that the number of calyces, petal, carpels, stamens is main factor,which causes the morphological variations in different population. Cluster analysis shows that 26 populations are incorporates in two types as 45.08 Euclidean distance. Leaf area index is distinct different in this two types.
