DETERMINING SOME OF THE TOMATO LINES REACTION AGAINST TSWV (TOMATO SPOTTED WILT VIRUS) BY THE MECHANICAL INOCULATION METHOD
2 Ankara Üniversitesi Ziraat Fakültesi Bahçe Bitkileri Bölümü-ANKARA Viewed : 2006 - Downloaded : 4211 In the tomato raising fields of Turkiye and in all around the world, TSWV -which is seen widely, caused the 42.1% to 95.5% of the product loss, recently. The most effective fight against the disease agent virus is the genetical resistance. The resistance to this disease is managed by the dominant Sw-5 gene, which is obtained from Solanum peruvianum. In this study, five tomato genotypes have different characteristics against virus disease were examined by the mechanical inoculation method-which can be used in breeding programms practically. Sensitive and resistant individuals were determined at the end of the mechanical inoculation studies by using the TSWV isolate (TSWV-15) which was obtained from Çamköy-Antalya region. In the testing period, as a resistant material, LA 3667-which contained Sw-5 gene was used. The other materials those were used in the study were, Çeşit-1 (resistant commercial variety; FORMULA F1), Çeşit-2 (a commercial variety; BATEM ÖZÇELİK F1 ), Hat-1 (BATEM-114 ) and Hat-2 (BATEM-115) (BATEM lines- the reaction against the disease are not determined). As a result of the testing study, Çeşit-1 and LA 3667 were assigned to be resistant to the TSWV-15 isolate. But, Çeşit-2, Hat-1 and Hat-2 were determined to be sensitive. This study is considered to be qualified enough to use for the future improvement programs for the resistance to the disease agent virus.
