Considering that rapeseed (Brassica napus L.) has a high use potential and its complex exploitation is an extremely topical research field in the context of diversification of raw material and energy sources, the present study tests the behavior of the main rapeseed genotypes recommended by specialists under temperature, humidity, and soil conditions of The Crișurilor Plain (Romania). The aim is to find optimal solutions to extend the cultivation area and increase the production capacity of this source rich in vegetable fats and proteins. A single-factor experiment with 5 varieties and hybrids of autumn rapeseed was carried out under optimal technical conditions in 4 repetitions. The following genotypes of autumn rapeseed were used as experimental variants: V1 - PR46W29 4; V2 - Maximus PT225; V3 - Maximus PT234; V4 - Sherpa; V5 - Perla. We evaluated the plants’ height, number of branches per plant, the height of insertion of the first siliquae, number of siliquae per plant, the weight of 1000 seeds, hectolitre mass, seed yield, the percentage content of protein, fat, oleic acid, linoleic acid and glucosinolates in the seeds. The recorded data recommend the Crișurilor Plain for the successful cultivation of four genotypes of autumn rapeseed under optimal and highly efficient conditions.
