Abstract
A vigorous partially fertile hybrid (2n = 32) between Caucasian clover, Trifolium ambiguum (2n = 4x = 32) ♀,and white clover, T. repens (2n = 32) ♂. has been produced with the aid of embryo culture. Hand polinations with self pollen and pollen from T. repens have yielded F2, F3, and backcross progeny.
