The El Niño-Southern Oscillation (ENSO) phenomenon or just El Niño, as commonly called, influences the climatic behavior in different areas of the world. In the case of Brazil, this phenomenon affects the northern part of the Northeast Region, the eastern Amazon (in the tropical area) and the extra-tropical area of the Southern Region. The climatic variability associated with the ENSO phenomenon phases, especially rainfall anomalies, may be quantified and this information can be effectively used by crop managers to reduce associated risks or to make better use of forthcoming favorable climatic conditions. The objective of this study was to identify the ENSO phases influencing wheat production in Brazil. The impact of these phases on grain yield was based on a historical series of yield data from 1920 to 1997. For 23 El Niño occurrences analyzed at national level, the deviations in wheat yield was negative in 61% of the cases. For 15 La Niña events, positive influences on wheat yields were observed in 73% of the cases. In the 40 neutral years, 55% of the time yield deviations were positive and 45% of the time were negative. Therefore, the ENSO phenomenon influences wheat yield in Brazil. In general, it causes positive impacts in La Niña years and negative impacts in El Niño years, particularly in the Southern part of the country. |

The availability of dense genomic information has increased genome-wide association studies for the bovine species; however research to assess the effect of single genes on production traits is still important to elucidate the genes functions. On this study the association of IGF1, GH, and PIT1 markers with growth and reproductive traits (birth weight, weaning weight, weight at 12 and 18 months of age, preweaning average daily weight gain, age and weight at first calving, and scrotal circumference at 12 and 18 months of age) were assessed by means of the variance component approach. The phenotypes were adjusted and then analyzed under two animal models, one which considered the polygenic and genotype (IGF1, GH or PIT1 markers) effects (Model 1), and the other which considers only the polygenic effect (Model 2). When the likelihood ratio test and the Bonferroni correction was applied at 5 % significance level, the genetic markers for the IGF1, GH, and PIT1 genes did not influence significantly the traits (p > 0.002). However, evidence of association of IGF1 with birth weight (p = 0.06) and GH with weight at first calving (p = 0.03) and with weight at 12 months of age (p = 0.08) was observed. In conclusion we could not confirm the associations between IGF1, GH, and PIT1 and growth traits that were previously reported in Canchim cattle, and no association was observed between these genes and reproductive traits. Future studies involving functional markers of IGF1, GH and PIT1 genes may help to clarify the role of these genes in growth and reproductive processes.
