Progenies of triploid and diploid hybrids of tetraploidArabis hirsuta (L.)Scop. s. str. and diploidA. sagittata (Bertol.) DC. andA. planisiliqua(Pers.) Reichenb. were studied. The observations concerned morphology, cytology, sterility degree of plants and embryological backgrounds. The evolutionary consequences of breakage of the sterility barriers within the complex connected with well pronouced morphological and karyological variability of hybrids are discussed.
