Basal leaf sections of Triticum aestivum L., cv. ‘Chinese Spring’, and X Triticosecale Wittmack cv.‘Welsh’were cultured on Kao's medium with 2 mg/l of 2,4‐D. Callus was induced on the leaf sections at frequencies of 64 and 63 %, respectively, and plant‐lets regenerated at 18 and 31 %, respectively. Compared to the controls, the regenerated plants showed higher frequencies of univalent chromosomes at meiosis and low frequencies of trivalents, and quadrivalents; indicating that the callus phase had induced low frequencies of chromosome irregularity.
