- Abstract
The sunflower (Helianthus annuus L.) is one of the four cultures of the largest production of edible oil worldwide, and stands out for its adaptation to different edafoclimatic conditions. The objective of this study was to evaluate the agronomic performance of ten cultivars of sunflower in northern Minas Gerais. The study was conducted at the Experimental Farms of the Agricultural Research Company of Minas (Epamig) in the municipalities of Jaíba, District of Mocambinho and Nova Porteirinha. The agronomic perfomance of these genotypes was evaluated by reviewing these characteristics: initial flowering, plant height, stem diameter, leaf number, circumference of the chapter, final stand, and yield. The data collected were subjected to variance analysis and the Scott-Knott test at 5% probability. There was variation in all parameters evaluated in agronomic behavior of genotypes, which showed good performance when grown in Mocambinho and Nova Porteirinha, in the north of Minas Gerais. All genotypes evaluated presented early cycle, with the exception of SYN 039A, which demonstrated a medium cycle. With the reduction of the crop cycle, there is also a reduction in the majority of variables
