Rice blast control with release of resistant varieties Introduction For the population of Russia rice grain is a valuable food, dietary and wholesome product [9]. The main rice-growing area in the country is the Krasnodar Territory. It produces more than 80% of Russian rice. In the last 5-7 years, rice growing dynamically develops every year increasing the yield capacity and rice paddy. In 2012 the rice farms of Krasnodar Territory got the record yield of 7.11 t/ha from 133,300 ha of the rice sown area. This is made possible through the introduction of new high-yielding rice varieties and improvement of rice cultivation including harvesting with modern rotary combines. A further increase in rice production is constrained by several factors, one of them being rice diseases and, above all, rice blast frequent in the majority of the rice-growing countries. The most effective way to combat the disease is to create and release to farmers rice varieties resistant to blast [10]. In the then USSR rice breeding aimed
