“…Egypt represents one of the producers and exporters of potato crops in Africa [1]. Recently, various pathogens causing potato tuber infections, particularly fungi of the genus Fusarium, which have become widely spread in Egypt [2,3]. In Egypt, the potato has a significant position among all types of vegetable crops, in a range of 20% of the whole area dedicated for vegetable cultivation, is grown with potatoes [4].…”

Potato (Solanum tuberosum L.) is one of the known five crops cultivated throughout the world after corn, barley, cereals, rice, and wheat, due to its content of high carbohydrates. In developing countries, potatoes are especially had valuable contents as a rich source of starch, vitamins C and B6, and essential amino acids. Fusarium solani species complex (FSSC) is one of the prevalent pathogens of potato, causing dry rot in Upper Egypt. In this study, FSSC were isolated and identified from potato tubers based on the morphological and molecular characteristics. F. solani isolates (187) were isolated from infected and noninfected potato tubers collected from various markets in Upper Egypt. Based on the morphology observations, sequence data from amplifying β‐tubulin, and specific translation elongation factor (TEF‐1α) genes, all of the chosen 88 FSSC isolates were grouped into three major groups (F. keratoplasticum, F. falciforme, and F. solani). All the tested FSSC were able to produce amylases. The selected isolates were examined for their pathogenic ability on healthy potato tubers, which exhibited pathogenic effects; with lesions sizes were quite variable. F. solani SVUFs73 showed a highly virulent effect.

Potato (Solanum tuberosum L.) is among the top five crops growing worldwide following cereals, wheat, rice, corn and barley due to its high carbohydrate content and adaptability. Potatoes are particularly valued in developing countries as a rich source of starch, vitamins C and B6 and essential amino acids. Fusarium solani species complex (FSSC) is common pathogen of potato, causing dry rot in the Upper Egypt. In this study were isolated and identified FSSC from potato tubers based on the morphological and molecular characteristics. 187 isolates of Fusarium solani were obtained from potato tubers collected from different regions in the Upper Egypt. Based on the morphological characters, sequence data from β-tubulin and translation elongation factor (TEF-1α) genes, all of the selected FSSC isolates were divided into three major groups (F. keratoplasticum, F. falciforme and F. solani). All the tested FSSC were able to produce amylases. All of the isolates were evaluated for their pathogenicity on healthy potato tubers; which showed pathogenic effect, lesion sizes were quite variable. F. solani (SVUFs73) had a highly virulent effect.

Potato (Solanum tuberosum L.) is an important crop which holds promise for food security considering the global population growth rate. Fusarium dry rot is one of the most significant diseases of potato. To build up strategies for the control of this disease, it ought to be made primarily a correct diagnosis and identification of the pathogen. A total of 504 Fusarium isolates were recovered from potato tubers collected from Upper Egypt. Fusarium isolates were identified based on morphology and partial DNA sequencing of β-tubulin (TUB) genes. 62.5% of the isolates were identified as F. sambucinum, followed F. oxysporum (57.5%), then F. verticillioides (56.25%) and F. incarnatum (47.5%). All the tested Fusarium species were able to produce amylase. The pathogenicity of the isolates was tested by inoculation of healthy potato tubers; all of the tested isolates were pathogenic to healthy potato tubers. F. sambucinum had a highly virulent effect.
