Summary A diallel cross was carried out among seven varieties of white clover to investigate the inheritance of some of those characters which affect potential seed yield. Peduncle length and number of seeds/floret have low narrow‐sense heritabilities, while peduncle length displays the added complications of heterozygosity and non‐allelic interactions. Consequently, improvements in these characters will be difficult. Seed number m ‐2 is a composite character which apparently exhibits heterozygosity. Higher seed yields will therefore be obtained by selection for its component characters, particularly floret number and floral density, both of which are apparently inherited in a comparatively straightforward manner. These results are discussed in the context of improving the potential seed yield of white clover.
