Some Wheat Varieties Behavior Regarding the Attack of Main Pathogens Under Climatic Conditions from Central Area of Moldavia, Romania

Open access

Abstract

Due to the attack of the main pathogens agents in the wheat crop the wheat production is not exploited at the full potential. Powdery mildew, leaf spot and rust brown leaves are considered to be the most widespread and damaging diseases of wheat. In our country, the attack of these pathogens is present every year, with different intensities and it can cause production damages ranging from 3-4% to 20%. Due to this fact, the main attention of the farmers is to cultivate resistant wheat varieties to Blumeria graminis (DC.) Speer., Septoria tritici Rob. Desm. and Puccinia recondita Rob. et Desm. The main objective of this study was to evaluate the phytosanitary condition of 24 wheat varieties cultivated in 2011-2012 at the Ezăreni didactic Farm from University of Agricultural Sciences and Veterinary Medicine of Iaşi, Romania, localized in the central area of Moldavia. This study contains data regarding the spread and evolution of the main pathogens that were observed at the 24 wheat varieties studied. These varieties showed different reactions to different pathogens observed in the same environmental conditions thus some of them were resistant to Blumeria graminis (DC.) Speer. and Septoria tritici Rob. ex. Desm. attack, and some recorded a disease incidence of 18.75% at the Puccinia recondita Rob. et Desm attack.
