Abstract

Protection of wheat from rust diseases caused by Puccinia spp. has very special significance for Georgia. The resistance to wheat stem, leaf and yellow rusts of 415 wheat cultivars and advanced breeding lines, consisted in 7st IYRTN and 8thIYRTN, 8th ISRTN and 9th ISRTN, and 5th ILRTN as well, were studied under natural infection in 2013-2014 years in different geographic zones of Georgia and important resistance sources including the cultivars with different Sr, Yr and Lr-resistance genes have been revealed.
