Culture of Explants from Immature Inflorescence of Octoploid Triticale

Sun Jing-san Sun Ching-san and Zhu Zhi-qing Chu Chih-ching   

Abstract: Immature inflorescence explants of octoploid Triticale cultured on MS medium with 2 mg/l 2,4-D showed high capacity for callus formation (100%) and subsequent plant regeneration on same medium. Chromosomes of regenerated plants were counted. Most of them showed 2n=56 which is a octoploid complement fur octoploid Triticale, but some plants were composed of decaploid cells with 70 chromosomes and aneuploid cells. The chiasma of homologous chromosomes in tip cell was found.

Key words: Triticale, Tissue culture
