Title : Study Resistance and reaction type number of genotype (Vicia faba L.) Uromyces viciae - fabae and definition of races and Status and strategies for improvement in Syria for season 2018 – 2019

Abstract:

The aim of this study is to recognize the resistance level of some faba bean genotypes and cultivars against Uromyces viciae – fabae ( Pers ) Schroet to investigate the existence of different physiological races of fungus . in Syria for the 2018- 2019 season. Eighteen genotypes and cultivars of faba bean ( viciae – fabae L . ) were selected from breeding materials of General Commission for Scientific Agricultural Research ( GCSAR) and some agricultural pharmacies that distribute seeds Resistance to bean rust disease (Pers) Schroet. Uromyces viciae - fabae Field and laboratories and the green house tests were carried out in National Commission for Biotechnology ( NCBT) . Through the seasons 2018- 2019.When more than 50% of faba bean plants were in flowering stage they were artificially inoculated with suspension of uredoenspores collected from several fields of early matured plants . The inoculation was carried out in excess moisture under polyethylene cover for 48 hours, The disease symptoms appeared after 11-12 days of inoculation .The disease severity and infection type were estimated using a scale ranging from ( 0 ) immune to ( 9 ) highly susceptibile according to the density and size of pustules on leaves and other parts of the plant . The results showed that temperature 25°C is the best that grows of rust urdiniospores and showed that five of the tested genotypes , Hama2 , seeds faba bean municipality( princes ), seeds faba bean ghouta AL sham, H 04/56 were highly resistant or resistant, while the others were nine genotypes and cultivars, Faba bean dafadei broad, HBP/SOE/ 2008, Faba bean Syrian Cyprian, H 04/ 57 , HBP/SOD/2007, REBAE 40, H 04/ 52 , Hama 3, HBP/SOD/2008 moderately resistant. Two genotypes S.81077 , Alaassi Spanish were susceptibile and Two genotypes were highly susceptibile ILB 1814 , Faba bean Syrian enhancer.Differential reactions of faba bean genotypes inoculated with four different isolates , illustrated that genetic variability existed among Uromyces viciae – fabae ( Pers ) Schroet in the region . this data indicated the presence of several physiological races in Syria but further studies are needed to determine their identity .
