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

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.
