In order to know the differences in yield components of three groups of varieties on the basis in plant type was studied in meadow fescue grown under plant basis. The results are summarized as follows; 1. The dry weight of a plant (PW) of the varieties indicated highly significant correlation with plant height (PH), weight of a tiller(WT), stem weight of a plant (SW) stem area (SA) and the efficiency of dry matter production per leaf area (PW/LA), but negative significant correlation with the efficiency of dry matter production per stem area (PW/SA). 2. The dry weight of a plant (PW) in tiller weight type, had positive significant correlation with plant height (PH), weight of a tiller (WT), stem weight of a plant (SW), stem area(SA), leaf area(LA) and specific stem weight (SSW), but negative significant correlation with specific leaf weight (SLW). But, there was not significant correlation with the efficiency of drymatter production per leaf area (PW/LA). 3. The dry weight of a plant (PW) in medium and tiller number type, had positive significant correlation with plant height (PH), weight of tiller(WT), stem weight of a plant(SW), stem area (SA) and the efficiency of dry matter production per leaf area(PW/LA), but negative significant correlation with the number of tillers per plant (NT). In medium type, had negative significant correlation with the efficiency of dry matter production per stem area (PW/SA). 4. The efficiency of dry matter production per leaf area (PW/LA) is an important functional factor for increasing the dry matter yield at late stage of growth (reproductive stage). Medium type showed a high efficiency of dry matter production per leaf area (PW/LA).
