Özet
Ülkemizde önemli bir üretim potansiyeline sahip olan fasulyede Bean common mosaic virus (BCMV), Bean common mosaic necrosis virus (BCMNV) viral hastalık etmenleri önemli verim kayıplarına yol açmaktadır. Son yıllarda yaygınlaşan moleküler markörler yardımıyla dayanıklılık genlerinin tespiti çalışmaları virüs inokulasyonu gerekmeksizin bitkilerde söz konusu genlerin belirlenebilmesini mümkün kılmaktadır. Bu çalışmada ülkemizde yer alan 43 tescilli fasulye çeşidinde BCMV ve BCMNV virüslerine karşı muhtemel dayanıklılık 3 farklı gen (bc-12, I, bc-3) ile ilişkili 4 farklı markör (SBD-5, SW-13, ROC11/420-350, eIFE4) yardımıyla incelenmiştir. Elde edilen verilere göre 43 fasulye çeşidinin BCMV ve BCMNV etmenlerine karşı dayanıklılıkta rol oynayan bazı genlere sahip olduğu belirlenmiştir. Elde edilen markör destekli tarama sonuçlarının virüs inokulasyonu ve patojenisite çalışmaları ile desteklenmesi öngörülmüştür. Söz konusu markörler yardımıyla yerel fasulye çeşitlerinin ve çeşit tescil adaylarının virüslere dayanıklılık genleri değerlendirilerek tescil özelliklerinin güçlendirilebileceği düşünülmektedir.
Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) pathogens lead to significant yield losses in common bean, which have a significant production potential in our country. The identification of resistance genes with the help of molecular markers has become widespread in recent years due to possibility to determine the genes in plants without virus inoculation. In this study, probable resistance to BCMV and BCMNV viruses in 43 commercial bean cultivars in our country were examined using 4 different markers (SBD-5, SW-13, ROC11/420-350, eIFE4) related to 3 genes ((bc-12, I, bc-3). According to the obtained data, 43 commercial bean cultivars were found to have some genes which play a role in resistance to BCMV and BCMNV pathogens. The obtained marker-assisted screening results are supposed to be supported by virus inoculation and pathogenicity studies. With the help of these molecular markers, it is considered that the registry characteristics of the common bean landraces and candidate beans for registration can be supported by checking the resistance genes of the viruses.
