Efficient plant regeneration system from leaf base segments of wheat (Triticum aestivum L.) was developed. The factors affecting the callus formation and regeneration capacity of leaf segments of two genotypes; Bobwhite and Pavon 76, were investigated. The highest number of somatic embryos (SE) was obtained on Murashige and Skoog medium supplemented with 2 mg dm-3 2,4-dichlorophenoxyacetic acid + 1 mg dm-3 naphthalenacetic acid (14.7 SE per segment). Highest frequency of embryogenic callus (96 %) and somatic embryo formation (24.3 SE per segment) were achieved in the first segments. The highest plantlet regeneration was obtained after transfer of embryogenic calli to regeneration medium supplemented with 1 mg dm-3 kinetin (6.3 plantlets per segment). © 2006 Institute of Experimental Botany, Academy of Sciences of the Czech Republic.
