| Water deficit stress is the abiotic factor with the highest impact on crop yield. The objective of this study was to evaluate grain yield (GY), the anthesis-silking interval (ASI) and drought tolerance indices in maize hybrids. We evaluated GY and the ASI of 86 hybrids under two moisture levels (normal irrigation and water stress) for three consecutive years. The stress susceptibility index, water stress tolerance, drought resistance coefficient, drought resistance index, stress tolerance index and harmonic mean were evaluated. There were significant hybrid x environment interactions for GY and the ASI. Differences in the ASI among environments ranged from 0 to 5 days. The hybrids P3862, 1I873, 1I923, 1I862 and 1J1211 showed high GY, associated with the... |

| A manipulação genética de plantas pode causar efeitos pleiotróficos ou mutações oriundas da incorporação de um gene exógeno, os quais podem interferir no forrageamento de herbívoros. Pouco se conhece sobre os efeitos de plantas de milho tolerantes a herbicidas (evento singular), plantas resistentes a insetos (evento singular) e plantas com tolerância a herbicidas e resistência a insetos (evento estaqueado) sobre o forrageamento de Spodoptera frugiperda. O objetivo deste estudo foi avaliar se eventos de milho, singular e estaqueado, interferem na quantidade e qualidade dos ovos de S. frugiperda. Foram avaliados os híbridos DKB390 (VTPRO, VTPRO2, VTPRO3), DKB390 (isogênico) e Ag 3700 RR2. Testes de preferência de oviposição, com e sem chance de escolha, em... |

| The adoption of biocontrol is low in maize production, although it has been reported reduction in fumonisin levels when combined with fungicides. The objective of this work was to evaluate the potential of Streptomyces araujoniae (BC1) and Bacillus sp. (BC2) combined or not with the fungicide azoxystrobin+ciproconazol (FG), on grain yield, Fusarium verticillioides incidence and fumonisin (B1 and B2) content. Maize plants were sprayed two times, at V9 and R1 with Water, BC1, BC2, Fungicide alone or in different combinations two by two. All plants were inoculated with F. verticillioides. Upon harvest, treatments were evaluated for total yield, F. verticillioides grain contamination (blotter test) and total fumonisin (B1+B2) contents. FG (V9) + BC1 (R1)... |

| ABSTRACT. Doubled haploid technology has been used by various private companies. However, information regarding chromosome duplication methodologies, particularly those concerning techniques used to identify duplication in cells, is limited. Thus, we analyzed and characterized artificially doubled haploids using microsatellites molecular markers, pollen viability, and flow cytometry techniques. Evaluated material was obtained using two different chromosome duplication protocols in maize seeds considered haploids, resulting from the cross between the haploid inducer line KEMS and 4 hybrids (GNS 3225, GNS 3032, GNS 3264, and DKB 393). Fourteen days after duplication, plant samples were collected and assessed by flow cytometry. Further, the plants were... |
