BIORESOURCES OF OATS FOR USE IN SELECTION FOR PHYTOIMMUNITY TO MUSHROOM DISEASES IN KIROV REGION
The research was carried out in the FSBSI FASC of the North-East in 2017-2020. The aim of the research is immunological and selective analysis of oats bioresources from the RIP collection and the search for effective sources of non-specific resistance for breeding in the natural provocative and infectious conditions of phytopathogen development. The soil of the experimental plots is sod-ash medium loamy on the eluvium of Permian clays. The meteorological conditions of the growing seasons had a favorable effect on the development of pathogenic fungi. The research material was 300 samples of filmy and naked oats. The gene pool is represented by samples from Russia, Belarus, Ukraine, Poland, USA, Canada, Bulgaria, Hungary, China and other countries. During the immunological analysis, it was found that 36 samples were characterized by high resistance to red-brown spotting (the degree of damage to the disease did not exceed 10%) and its slow growth (slow rusting), 27 samples - by fusarium panicle, and 100 samples had no symptoms of dusty smut. 13 samples were characterized by complex resistance to dust smut, panicle fusarium and red-brown spotting: Vector, 363 AC M6, 351 AC M3 (Russia), Gosha (Belarus); MF9521-214, 100433-4, 100433-5, Y201-150-8-19, AJAY (USA), OAC PAISLEY, CDC DANCER, AC FRANCIS (Canada), Ozon (Germany). Samples combining resistance to biotic stressors with high indicators of economically valuable traits were identified: 120h2106 (grain size 598 g/l, weight of 1000 grains 39,8 g), 351 AC M3 (grain size 600 g/l and weight of 1000 grains 40,4 g), WERVA (grain weight per plant 1,63 g, weight of 1000 grains 41,2 g, productive bushiness 1,5 pcs.), Ozon (grain size 628 g/l, panicle lake content 30-46 grains), Bohun (grain yield up to 1058 g/m2), AC FRANCIS (grain size 594 g/l, weight of 1000 grains 39,2 g), AJAY (grain size 608 g/l, weight of 1000 grains 40,4 g).
