Screening for Resistant Germplasms and Quantitative Trait Locus Mapping of Resistance to Tomato Chlorosis Virus.

ABSTRACT: Tomato chlorosis virus (ToCV) is an emerging plant virus that poses a substantial threat to the cultivation of economically vital vegetable crops, particularly tomato (Solanum lycopersicum). Despite its substantial impact on crop yield, resistant or tolerant tomato germplasms have not been well documented, and the genetic basis of resistance to ToCV remains poorly understood. In this study, two wild accessions that were immune to ToCV and five accessions that were highly resistant to ToCV were identified from 58 tomato accessions. Additionally, a novel method was developed for evaluating resistance to ToCV in tomatoes, and it was observed that tomatoes exhibited typical pathological features on days 15 and 30 after ToCV inoculation, referred to as Stage 1 and Stage 2, respectively.
