Research aim was to test the tolerance of a range of maize hybrids to infectious pressure of the pathogen Fusarium graminearum in climatic conditions of Almaj Depression. Stage of the present research is being characteristic for partial interpretation of experimental data after the first experimental year, in preparation the doctoral thesis. Experimental field was located in climatic conditions Almaj Depression. Technology was the standard applied to this area. The experience was bifactorial. First factor was the hybrid grown with six graduations, provenance hybrids was Monsanto with different vegetation periods, (DKC 3511, 4626 DKC, DKC 4964, 4983 DKC, DKC DKC 5783 and 5170). Factor B was the plant density with tw graduations (N 0 , N 100 and N 200 ) all three doses were applied on a constant background of elements consisting in P 80 K 80 . The novelty is relatively high, work providing important data for agricultural practice in the experimental area, taking in consideration the implications of fungus Fusarium graminearum in yield preservation during winter in normal farm conditions. Achievements in this paper are that the experimental data come from researches of the possible reactions of the pathogen depending on local biocoenosis factors. Limits of the research are given by the fact that data from the fungus Fusarium graminearum are just after one year of  bonitation. Practical implications of the present research consisted from that the presented data has an important place in a complex study of strategy of maize protection experience. The originality of the work comes from the fact that data are relevant in view of uniformity of hybrid origin and also these data are only part of the data submitted for interpretation in the preparation of the doctoral experience of the main author.  Importance of the paper became from bringing in front of the specialists of one of the topics in the experiences of the author's doctoral preparing, to evaluate the accuracy of techniques addressed. The relevant data, experimental results give an overview of pathogen behavior in relation to hybrids experienced by groups of precocity.
