The field investigation and indoor identification were conducted on distribution,surrounding,flower and fruit period and main characters of wild bentgrass resources in Guizhou province.The resource quality and lawn characters have been evaluated comparatively.The results showed that 6 wild grass plants of bentgrass were distributed in Guizhou province.They were as follows:creeping bentgrass (A.stolonifera),slight bentgrass(Agrostis tenuis),bentgrass(A.matsumurae),stick bentgrass(A.clavata),mangflower bentgrass(A.myriantha)and short handle bentgrass(Agrostis brevipes).The comparative studies were made between 6 native resources and 2 import varieties(Cato and Putter)and their characters were scored by 9 systematic evaluation.It was demonstrated that the lawn guality.of Cato was prior to wild material,but Putter was inferior to wild material.Each material expressed diversity and variation.
