| description | Blast disease is a widely spread and harmful disease of rice. The most reliable method to fight with it is a development of resistant varieties. The article presents the development stages of the new rice variety 'Partner' with higher resistance to blast disease. It has been shown that on the basis of DNA-markers we developed breeding material with a gene of resistance to blast disease Pi-b. The donor of the gene Pi-b was the later maturing Japanese variety 'BL-1'. The recipient was the variety 'Yantar' cultivated in theKrasnodararea. The obtained material allowed identifying and studying 20 lines in the breeding seed plot. The estimation of the material in the breeding seed plot resulted in the identification of five best lines and their introduction into the control seed plot. According to the complex of economic traits two variety samples 'KP 117-09' and 'KP 126-09' were identified. The variety sample 'KP 117-09' showed 24.9 % of blast disease development during artificial infection, 'KP 126-09' had 27.7%. The rest varieties including the standard variety 'Rapan' had a larger percent of infection (42.7%). In 2011-2013 the identified samples were subjected to a competitive testing. According to the results the variety sample 'KP 117-09' (named as 'Partner') was found the best and was sent to the State Variety Testing. On average the variety 'Partner' showed better productivity that 'Rapan' (8.54 and 7.93 t/ha respectively); it surpassed the standard variety in the trait '1000-kernel weight' (32.3 gvs 28.0g) and in resistance to blast disease (22.6% vs 48.7%). The other traits of the comparing varieties had the close values. In 2013 the new variety 'Partner' was sent to the State Variety Testing. Due to two years of study it was introduced into the List (Register) of Breeding Achievements and since 2016 it was approved for use in the Krasnodar Area. |
