Abstract

Aim. Develop inheritance model for glume color in hybrid generations considering introgressive origin of crossing components. Methods. Phenotypic assessment of the trait, cytological study of chromosome conjugation in meiosis, methods determining statistical significance of the results. Results. Twelve cross combinations of wheat introgressive with one another and with recurrent genotype Aurora were studied. Selected for the crosses introgressive lines had contrasting glume color trait. Characteristics of wheat introgressive lines and its hybrids which would be important in hybrid analysis for the development of the inheritance model were identified. Genetic analysis of the introgressive lines was done as for the number of glume color genes for which lines differed from one another and from the Aurora genotype. Conclusions. In case the critical gene in localized in a chromosome that do not conjugate with hom(e)olog of the cross partner, F1 hybrids developed with introgressive lines form gametes and zygotes with frequencies differing from theoretically expected for the cross of homozygous lines.

Keywords: wheat introgression lines, Aegilops, glume colour, aneuploidy gametes and zygotes, meiotic drive.
