Recovery of fertility in regenerants of Triticosekale wittmack, obtained by the method of artificial androgenesis

The possibility is discussed for biological method of fertility recovery in androclinal regenerants of hexaploid triticale. It was shown that the sterile anthers in regenerants cause the formation of viable zygotes in field conditions as result of free fertilization in body of triticale variety-pollinator. The increased tilling capacity in haploid forms and microclonal cultivation of regenerants in vitro permits to obtain the large amount of hybrid seeds resulted in increasing genotypic variability store, which is connecting with accumulation in hybrid zygote of mutations (somaclonal variability) and recombinations. The biological method permits to use efficiently triticale androclinal regenerants in breeding.
