Resumo: Com o objetivo de avaliar o comportamento agronômico de genótipos de girassol no cerrado do Distrito Federal, foram conduzidos ensaios na safrinha dos anos de 2011 e 2012, em delineamento experimental de blocos ao acaso com quatro repetições. Os caracteres avaliados foram rendimento de grãos, tamanho do capítulo, peso de mil aquênios, altura de plantas, dias para floração inicial e teor de óleo. Foram observadas diferenças altamente significativas entre os genótipos para todas as características morfoagronômicas avaliadas. Em relação ao rendimento de grãos, em 2011, esta característica variou de 2.376 kg.ha (SRM 822) a 5.490 kg.ha (BRSG 30) e, em 2012, de 2.306 kg.ha (V60415) a 4.412 kg.ha (SYN 039A). Materiais genéticos promissores para as características agronômicas avaliadas foram identificados no trabalho, podendo ser explorados comercialmente em condições de safrinha do Cerrado. Abstract : Aiming to evaluate the agronomic performance of sunflower genotypes in the Savannah of the Federal District, experiments were conducted in the second crop of 2011 and 2012 in a randomized block design with four replications. The characters evaluated were grain yield, head length, weight of thousand achenes, plant height, days to initial flowering and oil content. Differences among genotypes for all traits morphoagronomic were highly significant. In relation to grain yield in 2011, this feature[ ranged from 2376 kg.ha (SRM 822) to 5,490 kg.ha (BRSG 30) and, in 2012, from 2,306 kg.ha (V60415) to 4412 kg.ha (SYN 039A). Genetic materials promising for agronomic traits were identified in work and can be commercially exploited in the second crop of Savannah.

Although alfalfa (Medicago sativa L.) is a leguminous herbage widely used in temperate regions as animal feed, there is not much research in tropical regions to develop cultivars adapted to these environmental conditions. The utilization of adapted cultivars with adequate management practices is important to improve productivity, quality and persistence of cultivated pastures. The objectives of this study were to verify the genetic variability among alfalfa cultivars and to rank them using mixed model methodology. A total of 35 alfalfa cultivars were evaluated in the rainy and dry seasons, from 1996 to 2000, in plots of 2.8 m2 in Sertãozinho, São Paulo, Brazil. The experimental design was a randomized complete block with three replications. Longitudinal data of dry matter yield were analyzed using PROC MIXED of SAS® System. Several covariance structures were tested and the spherical spatial structure was selected. The results show that the genetic variability was statistically significant only for the dry season. Moreover, the interaction among cultivars and harvests variance was highly significant for both seasons. The empirical best linear unbiased predictions of cultivar effects were obtained, allowing for the selection of the superior cultivars MH 15, 5715, SW 8210, Rio, High, 5888, Monarca, Victoria, Florida 77 and Falcon. Crioula, the most common cultivar in Brazil, showed low forage potential in Sertãozinho. Results indicate potential for use of more productive cultivars of alfalfa to produce animal feed in tropical environments.
