Eight strains of white clover were compared under a cutting treatment over a three‐year period. The medium‐leaved, persistent strains S.100, S.100 Nomark, Kersey, New Zealand CM. and P.P. generally gave the highest yield of clover, but this was counterbalanced by an increased yield of unsown species in the plots of wild white clovers S.184 and Kent.The unsuitability of Ladino clover for British conditions was shown by its lack of persistency and poor yield. The new strain S.100 Nomark gave a similar total yield to S.
