[Correlation and path analysis of agronomic characters of Panax notoginseng].
OBJECTIVE
To select the main directions and the objects in breeding the high yield of Panax notoginseng by the correlation and path analysis of main agronomic character of P. notoginseng.


METHODS
Samples in fifty-two districts of Yunnan and Guangxi were collected. The height of plant, the diameter of stem, the number, length, width, size of leaf and the weight of each root of those samples were measured.


RESULTS
The greatest contribution to the weight of each root is the size of leaf.


CONCLUSIONS
The size of leaf should be key to the high yield of cultribution of P. notoginseng and the size of leaf especially the width of leaf should be selected in breeding. At the same time, the height of plant and the diameter of stem should be considered.
