Forty‐two noninbred zigzag clover plants were evaluated for self‐compatibility and all were highly self‐incompatible. Variation for cross‐compatibility of F 1 plants from self‐incompatible parents was continuous. The results indicate that the inheritance of self‐ and cross‐incompatibility in zigzag clover is complex. A highly significant difference was found among 64 plants under field conditions for open‐pollination seed set. Damage due to the clover seed chalcid reduced seed set considerably.
