The mixo ploid derived from tri ploidy hybridization in mulberry tree

, : The mixo ploid derived from tri ploidy hybridization in mulberry tree. Journal of Sericultural Science of Japan 49(4): 288-293

Mixoploids were detected in the F1 progeny among the cultivars Ichinose, Kairyo-nezumigaeshi, Kenmochi, Nezumigaeshi, Riso, and their colchicine-induced tetraploids. The cells of the leaves of the mixoploids were mixed with triploid cells (2n = 42) and hexaploid cells (2n = 84), and many gigantic cells were found around the hexaploid cells. Mixoploids were commonly characterized by irregular leaf shape, a malformed leaf tip, margin and base, twisted and asymmetric leaf veins and irregular phyllotaxis. Leaf color showed variegation and the leaf surface was coarse and uneven. Leaf cross-sections revealed that cuticle, epidermal cells and palisade parenchyma were abnormal, that the arrangement of these 3 layers was irregular, that leaf thickness varied markedly and that tissues of the veins were abnormal. Measurements were made of branch length and leaf size with the trees which developed mixoploid branches as well as triploid ones. In the mixoploid, branches were short and leaves of each order were small, as compared with the triploid. In the mixoploids, sprouting was delayed and irregular as compared with the triploid.
