| Abstract Zucchini yellow mosaic virus (ZYMV) is one of the most economically important viruses of cucurbit crops, causing severe mosaic, blistering of leaf lamina, malformation, and knobbed fruits, and presents an important biological variability. The objective of this study was to determine the prevalence and incidence of ZYMV in major summer (Cucurbita pepo), and winter squashes (C. maxima, and C. moschata) growing areas of Turkey-Samsun. Field surveys were made in 2015-2016 cropping seasons in major cucurbit growing regions. In five regions, 225 symptomatic samples were collected. Samples from three different species of Cucurbita were tested by biological and serological method using ZYMV polyclonal antiserum. Serological test results revealed that 84... |

| In this work, the part of the squash core collection, maintained in the Greek Gene Bank, was assessed using the morphological and molecular data. Sixteen incompletely classified accessions of the squash were characterized along with an evaluation of their resistance against two isolates of Fusarium oxysporum. A molecular analysis using Random Amplified Polymorphic DNA (RAPD) markers was also performed, revealing high level of polymorphism. To study the genetic diversity among the squash accessions, a clustering procedure using Unweighed Pair Group Method and Arithmetic Average (UPGMA) algorithm was also adopted. Two independent dendrograms, one for the morphophysiological and one for molecular data were obtained, classifying the accessions into two and... |
