title: [The influence of combinations of alien translocations on in vitro androgenesis in near-isogenic lines of spring bread wheat].
abstract: The features of in vitro androgenesis were studied in Cultured anthers of spring bread wheats L503 and Dobrynya, having 7DS-7DL-7Ae#1 L translocation with genes Lrl9/Sr25 (Lrl9 translocation) from Agropyron elongatum (Host.) P.B. and their near-isogenic lines carrying combinations of Lrl9 translocation with translocations: 1BL-IR#1S with genes Pm8/Sr31/Lr26/Yr9 (Lr26translocation) from Secale cereal L., 4BS-4BL-2R#1L with genes Lr25/Pm7 (Lr25 translocation) from Secale cereal, 3DS-3DL-3Ae#1L with genes Lr24/Sr24 (Lr24 translocation) from Agropyron elongatum and 6BS-6BL-6U#1L with gene Lr9 (Lr9 translocation) from Aegilops umbellulata Zhuk. In comparison with those varieties having received the Lrl9 translocation, the following was established: (1) the combination of translocations Lr19+26 increased embryo frequency and green plant regeneration; (2) the combination of translocations Lr19+9 decreased embryo frequency but increased green plant regeneration; (3) the combination of translocations Lr19+24 decreased embryo frequency but increased green and albino plant regeneration; (4) the combination of translocations Lr19+25 increased embryo frequency and green plant regeneration but decreased albino plant regeneration. Thus, on near-isogenic lines of spring bread wheat, the influences of genotypes of four alien translocation combinations on in vitro androgenesis were determined.
