Quality evaluation of some maize hybrids cultivated under pedoclimatic conditions of Banat area (West of Romania)

The purpose of the researche is to follow the influence of the biological factor on quality of eight maize hybrids of various maturity groups Florencia(FAO 500), ZP 409(FAO 500), Fundulea 376(FAO 500), Olt(FAO 430), TC 377(FAO 390), Stira (FAO 390), Garbure(FAO 370) and LG 3395(FAO 370). An experiment was set up on a cambic chernozem at Timisoara(west of Romania) in 2010, in a randomised block design with four replications, the level of fertilization being N130P60K60. Quality parameters that were monitored to determine the quality of maize cultivars are moisture, hectoliter mass, protein, oil, and starch content. We can conclude that influence of genetic background of various types has been different for yield and quality parameters. Regarding the correlations between quality parameters of maize hybrids our researches leaded us to the conclusion that between protein content and oils content there was a positive correlation but between hectoliter mass and starch content the correlation was negative.
