A hybrid between <i>Trifolium repens</i> and <i>T. ambiguum</i> obtained with the aid of embryo culture

Abstract

Abstract A sterile, stoloniferous hybrid (2n = 32) between Caucasian clover, Trifolium ambiguum (2n = 4x = 32) ♀ and white clover, T. repens ♀ has been produced with the aid of embryo culture using transplanted nurse endosperm. Vegetatively the hybrid strongly resembles T. repens , but several vegetative and floral characters are modified towards T. ambiguum . Hybridity is supported by the presence of heterologous nucleolus‐organising chromosomes and by the results of gel electrophoresis of leaf isozymes.
