Exploration of non-phytopathogenic Aspergillus spp. isolates recovered from soil and compost as potential source of bioactive metabolites for potato Fusarium dry rot control.

During storage, infected potato tubers by Fusarium species leads to significant losses. Searching natural-based alternatives to chemical fungicides for the control of tuber dry rot pathogens is becoming essential. Nine Aspergillus spp.

Varietal Screening of Durum Wheat Varieties for Resistance to (Tan Spot) under Field Conditions.

Tan spot disease caused by was becoming more bred in Tunisia during the last decade. The search for resistant varieties against the increased virulence diversity of is presently considered as a priority. Seven of the most commercialized durum wheat varieties in Tunisia (cvs.

Detection of Maternal and Cytoplasmic Effects on Resistance to in Durum Wheat.

Septoria tritici blotch (STB) is a major disease problem of wheat worldwide. To optimize the introgression of resistance genes in elite genotypes throughout traditional or molecular breeding programs, a full understanding of the quantitative inheritance of resistance to , plant height (PH), and thousand kernel weight (TKW) is needed. In this study, maternal and cytoplasmic effects of resistance to STB were investigated using P1 (susceptible, high-yielding line) and P2 (resistant, low-yielding line) durum wheat lines and their F, RF, F, RF, BC, RBC, BC, and RBC progeny, assessed for resistance to STB during three growing seasons.
