Abstract: Sunflower (Helianthus annuus L.) is an oleaginous crop of great economic importance worldwide due to the beauty of its flowers and the nutritional quality of seeds. The influence of the environment on grain yield and the agronomic behavior of other variables in the studied genotypes in the cycle February-June 2019 of the crop in the Municipality of Marín, N.L. The experimental design was a completely randomized blocks designes with 6 treatments and 4 repetitions. Based on the variables analyzed, the genotypes obtained satisfactory results, the highest grain yield was of the Jaguar variety with 3.72 t ha^-1, as well as the larger diameter, weight of the flower with 12.95 cm and 188.20 g, greater length, width and seed weight with 1.48, 0.48 cm and 11.33 g, the lowest percentage of seed moisture was Hornet with 6.85%.
