Main quality parameters’ evolution of the wheat cultivated in Romania during the last years

Abstract

There have been analyzed 670 wheat samples from the 2002, 2003, 2004 and 2005 crops, in order to establish the quality characteristicsí yearly evolution.

Our results show that Romanian wheat crops have been characterized by high values for the variation coefficients, associated with the quality parameters which describe the seed enzymatic activity (gluten deformation and falling number). The most constant quality parameters of Romanian wheat are Hectolitric Weight (Test Weight), Moisture and Protein Content. The most different crops from a qualitative point of view are those obtained in 2002 and 2005, which were years characterized by completely different climatic conditions. 

The medium (multiannual) mean coefficient for establishing the relationship between the protein content and the wet gluten was 0.750 for Romanian wheat, value corresponding to a medium correlation coefficient of 0.866.
