Transmission of 5R Chromosomes via Gametes and Its Influence on Spring Bread Wheat Somatic Embryoidogenesis in Vitro

Transmission of chromosomes 5R via gametes and its effect on somatic embryoidogenesis have been studied with the use of the model 5R(5A) substitution line L2837 = L503/Secale cereale L., cultivar Saratovskaya 5//L503, where L503 is a cultivar of spring bread wheat. It has been found that the frequen...

Description
Summary:Transmission of chromosomes 5R via gametes and its effect on somatic embryoidogenesis have been studied with the use of the model 5R(5A) substitution line L2837 = L503/Secale cereale L., cultivar Saratovskaya 5//L503, where L503 is a cultivar of spring bread wheat. It has been found that the frequencies of transmission of univalent chromosomes 5R and 5A determined in experiments on F sub(1) reciprocal hybrids with cultivar Saratovskaya 29 do not reflect their frequencies in the self-pollinated offspring of F sub(1) hybrids; the frequency of transmission of chromosomes 5R and 5A depends on the genotypes of both the recipient cultivar and the donor rye cultivar; and the 5R(5A) substitution in cultivar L503 significantly increases the parameters of somatic embryoidogenesis in vitro in explants from inflorescences.
