This experiment was carried out to investigate the varietal differences of heading dates in both intra and inter-plants, and the relationship between heading dates and dry matter production in meadow fescue(Festuca pratensis L.). The results obtained are summarized as follows; 1. Durations of heading per heading tiller(DH/HT) had positive significant correlations with require days to heading(HD) and dry weight of a heading tiller(WHT), but negative significant correlations with dry weight of a plant(DW), durations of heading(DH) and the number of heading tillers per plant(HT). 2. The variations of heading dates in intra-plant were larger than those in inter-plant. 3. Heading dates within the whole cultivars were correlated positively with the variations of heading dates in intra-plant. And, the variations of heading dates in intra-plant had positive significant correlations with inter-plant.
