Biber Hatlarının Domates Benekli Solgunluk Virüsüne (TSWV) Dayanıklılık Bakımından Moleküler Analizi

Year 2025, Volume: 5 Issue: 2, 1 - 10, 30.09.2025

Abstract

Bu çalışma, 35 farklı Capsicum biber hattının Domates Benekli Solgunluk Virüsü'ne (TSWV) karşı moleküler dayanıklılık durumunu belirlemek amacıyla yürütülmüştür. PCR amplifikasyonu, tsw dayanıklılık genini hedef alan SCAC₅₆₈ CAPS markörü kullanılarak gerçekleştirilmiştir. PCR ürünleri XbaI restriksiyon enzimi ile kesilmiş ve daha sonra agaroz jel elektroforezi ile analiz edilmiştir. Elde edilen DNA bant örüntülerine dayanarak, genotipler sınıflandırılmış ve 22 biber hattının heterozigot dayanıklı (Rr), 13 hattın ise duyarlı (rr) olduğu ortaya çıkmıştır. Belirlenen dayanıklı bireyler daha ileri seleksiyon ve patojenite testlerine tabi tutulacak ve melez ıslah programlarına entegre edilecektir. Bu çalışma, yerel tohum ıslah çalışmalarına katkıda bulunmakta ve markör destekli seleksiyonun TSWV'ye dayanıklı Capsicum çeşitlerinin geliştirilmesi için etkili ve güvenilir bir strateji olduğunu göstermektedir.

Molecular Analysis of Capsicum Lines for Resistance to Tomato Spotted Wilt Virus (TSWV)

Year 2025, Volume: 5 Issue: 2, 1 - 10, 30.09.2025

Abstract

This study was conducted to determine the molecular resistance status of 35 different Capsicum pepper lines against Tomato Spotted Wilt Virus (TSWV). PCR amplification was performed using the SCAC₅₆₈ CAPS marker targeting the tsw resistance gene. The PCR products were digested with the XbaI restriction enzyme and subsequently analyzed by agarose gel electrophoresis. Based on the resulting band patterns, the genotypes were classified, revealing that 22 lines were heterozygous resistant (Rr), while 13 lines were susceptible (rr). The identified resistant individuals will be subjected to further selection and pathogenicity testing and integrated into hybrid breeding programs. This study contributes to local seed improvement efforts and demonstrates that marker-assisted selection is an effective and reliable strategy for developing TSWV-resistant Capsicum cultivars.
