Seed shedding was studied in 50 clones each of S5I and S48 timothy during 1961–3. Some clones retained on average during 2 or 3 seasons from 80–90% of their maximum seed weight until 42 days after peak anthesis; this was up to 28% above the varietal mean. The results suggest that clones which retain their seed also produce high yields of seed and of dry matter; they can also be easily threshed.
