Abstract

Grafted watermelon production on different gourd rootstocks has become widespread in

major watermelon production areas of Turkey. Zuccini Yellow Mosaic Virus (ZYMV) is one

of the most damaging virus diseases in cucurbitaceous plants. Seed-transmission of ZYMV in

gourd makes it more remarkable virus disease. Therefore ZYMV resistance sources should be

added to rootstock breeding programs in gourd. In this paper we aimed to screen our gourd

genotypes for ZYMV. We screened our gourd germplasm included 340 accessions for major

virus diseases infections. The results showed that 188 genotypes (55%) were found to be

infected by ZYMV, 71 genotypes (21%) by Watermelon Mosaic Virus (WMV) 40 genotype

(12%) by Cucumber Mosaic Virus (CMV) single or mix infection and the rest was virus-free.

Then seeds were collected from ZYMV infected plants. Seeds were sown and seedlings were

tested serologically and RT-PCR techniques for ZYMV, WMV and CMV. We observed that

ZYMV was transmitted by seeds in 3.19 % of the infected genotypes As a result of the

observations; we have convinced that some of the gourd lines should be tolerant against to

ZYMV
