Fifteen varieties of autumn wheat, most of them recently approved, were tested in an ecological system in the
experimental field at ARDS Simnic. For two years (2016 and 2017) determinations have been made regarding height,
number of spice/mp, yield, test weight, weight of 1000 grains, number of grains/ear, weight grains/ear and protein
content, both in ecological and conventional systems, last as a reference base. The differences were presented
percentually to see to what extent the ecological system influenced the determined characters. The control used were
the average of all tested varieties and the Alex variety - that showed the highest average yield in the ecological system.
In ascending order, the studied characters were affected by ecological system in relation to the conventional system, on
average, as follows: yield (52.6%); weight grain/ear (69%); number grains/ear (69.1%); height (83.9%); number spice
/mp (84.2%); protein content (89.6%); the weight of 1000 grains (96.9%); test weight (102%) - the only uninfluenced
character. In relation to Alex variety, only Litera variety showed significantly higher reductions in terms of test weight,
number of graines/ear and weight grains/ear. Compared to the average of the varieties, significant differences were
noted only at the test weight in Miranda (+ 4.2%) and Ursita (-7.1%). The results suggest that the ecological system
influenced the characters studied, indifferent of the varieties tested
