Study of tolerance to Tomato spotted wilt virus in tomato genotypes with anthocyanins content.
Bistra Dikova, Bistra Dikova, Elena Balacheva, Bistra Atanassova
Abstract: Tomato spotted wilt virus (TSWV) is one of the ten most widespread plant viruses in the world that causes diseases strongly affecting plant development and yield. The objective of the study was to determine the tolerance to TSWV of four tomato genotypes differing in anthocyanins content in their leaves and stems. The percentage of symptomless healthy plants among the four genotypes varied as follows: Keti (AA1) – control - 21% symptomless healthy plants; line St 993 x Keti (AA7) - 5% symptomless healthy plants, AA10 (VK1 x Keti) – 31% symptomless healthy plants and AA12 (VK1 x Keti) – 25% symptomless healthy plants. It is important to note that line AA10 was characterized by high productivity and tolerance to environmental conditions. No correlation was detected between the high content of anthocyanins in plant tissue and the high tolerance to TSWV.
