| In this paper, about 60 strips of wild Hemarthria compressa germplasm resources in the southwest china were be studied. The targets were about of synthetically analyzed and evaluated germplasm characteristics such as component composition, morphological property, grow behaviour, production performance, resistance performance, physiological and biochemical basis, hereditary basis and the way of use, etc. The resultshows as follows:1) There existed diversity among quantitative character in the different populationcomponents. The coefficient of variation(CV) for leaf length, leaf width, leaf number of each tiller and leaf number of each cloned plant was 24.95%,20.00%,14.12%,43.56%,respectively. The CV for stem diameter, eustipes daimeter, eustipes length, eustipes number of each tiller, the length of erect stem and stolon stem, and the number of erect stem and stolon stem was 21.11%, 22.42%, 20.10%, 12.14%, 46.73%, 20.14%, 72.76%, 37.97%, respectively. The CV for root length, the range of roots, the area of roots was 21.11%, 22.42%, 20.10%, 12.14%, 46.73%, 20.14%, 72.76%, 37.97%,respectively. The CV for the length, width and thickness of inflorescence, inflorescence number of each tiler, the ratio of erect stem to seminal branch and the ratio of stolon stem to seminal branch was 13.33%, 13.42%, 14.80%, 36.10%, 118.96%, 81.44%, respectively. Meanwhile, the rich diversity for biomass structure in different population components was found. The CV of biomass for leaf, stem, root and inflorescence was 78.51%, 91.66%, 45.64%, 192.24%, respectively. Moreover, the quantitative difference of each component was higher than its characteristic difference. The rich ecotype and environmental suitability for these wild resources are very beneficial to selecting and using excellent breeds and strains.2) For the cloned plant, there is a difference in the time of root formation, the depth of...
