THE STUDY OF A HOST PLANT GENETIC DIVERSITY TO THE TRANSCAUCASIAN POPULATION OF WHEAT YELLOW RUST (PUCCINIA STRIIFORMIS WEST. F. SP. TRITICI ERIKSS. ET HENN.) PATHOGEN
03.00.00 Biological sciences
Description
The immunologic characteristics of 18 domestic winter wheat cultivars to Transcaucasia population of yellow rust pathogen have been studied. 251 resistance sources to Puccinia striiformis have been detected among 468 studied soft wheat samples from Vavilov ARRIP collection. The efficiency of known resistance genes (Yr) to Transcaucasia population of yellow rust pathogen are estimated

RESISTANCE SOURCES OF WHEAT AND AEGILOPS TO STEM RUST (Puccinia graminis Pers. f. sp. tritici Erikss. et Henn. pathogen)
03.00.00 Biological sciences
Description
The search of resistance sources to the wheat stem rust pathogen among wheat collection material, its rare species and Aegilops (goat grass) was conducted. The samples resistant to the pathogen were detected. They have been studied on the artificial infectious background for three years and they are recommended for use in selection
