[The influence of combinations of alien translocations on in vitro androgenesis in near-isogenic lines of spring bread wheat].

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.

Genetic analysis of anther culture response in wheat carrying alien translocations.

A bread wheat cultivar, 'Saratovskaya 29', (S29), its nearly isogenic lines carrying alien translocations [Lr9 from Aegilops umbellulata (Eg29) and (Lr19) from Agropyron elongatum (Ps29)] and two F1 hybrids between three nearly isogenic lines of S29 that differed by the Lr19+Rht1,Pro1+Pro2 and Ppd1+Ppd2 gene complexes, namely the S29 (Lr19+Rht1)/S29 (Ppd1+Ppd2) F1 and the S29 (Pro1+Pro2)/S29 (Lr19+Rht1) F1 were studied for their culture response with the following results. (1) Translocations with Lr9 and Lr19 decreased embryo frequency and green plant regeneration. (2) Both F1 hybrids showed a decrease in embryo frequency.
