13. Recurrent selection of popcorn composites UEM-CO1 AND UEM-CO2 based on selection indices
ABSTRACT Selection indices were applied to data sets of 169 half-sib families of the popcorn composites UEM-Co1 and UEM-Co2 in four cycles of recurrent selection. From 2005 to 2008, the experiments were arranged in a 13 by 13 lattice square design, with two replications per cycle and composite. Genetic gains for popping expansion (PE) and grain yield (GY) we

14. Potential of popcorn germplasm as a source of resistance to ear rot
ABSTRACT Because of its multi-purpose nature, popcorn has sparked the interest of the World Trade Organization as regards fungal contamination by mycotoxins. However, no investigations have been conducted on popcorn for resistance of genotypes to ear rot. The aim of this study was to evaluate the potential of popcorn genotypes as to resistance to ear rot and

15. Effect of recurrent selection on the variability of the UENF-14 popcorn population
Abstract This study aimed to evaluate the effect of recurrent selection on the genetic variability of UENF-14 population after six selections. Two hundred and ten half-sib families were evaluated in two environments in the state of Rio de Janeiro, using incomplete randomized blocks design with treatments arranged in replication within "Sets". There was signi

16. Linkage disequilibrium, SNP frequency change due to selection, and association mapping in popcorn chromosome regions containing QTLs for quality traits
Abstract The objectives of this study were to assess linkage disequilibrium (LD) and selection-induced changes in single nucleotide polymorphism (SNP) frequency, and to perform association mapping in popcorn chromosome regions containing quantitative trait loci (QTLs) for quality traits. Seven tropical and two temperate popcorn populations were genotyped for

17. Occurrence of zearalenone in wheat- and corn-based products commercialized in the State of Paraná, Brazil
The productivity of wheat and corn crops depends on climatic conditions and resistance against phytopathogenic fungi such as those of the genus Fusarium. Some species of this genus produce zearalenone (ZEA), a mycotoxin with hyperestrogenic effects. The objective of this study was to investigate the presence of ZEA in samples of cracked wheat (n = 109), popc

18. Corpo estranho traqueal em cão
The occurrence of a tracheal foreign body in a three-month-old male Poodle referred to a Teaching Veterinary Hospital due to acute coughing, gagging and nausea is reported. A bronchoscopy under general anesthesia was performed in order to obtain a diagnose. During the bronchoscopy a foreign body (maize popcorn) was observed in the intrathoracic trachea. The

19. Multivariate analyses of genotype x environment interaction of popcorn.
The objectives of this work were to evaluate the genotype x environment (GxE) interaction for popcorn and to compare two multivariate analyses methods. Nine popcorn cultivars were sown on four dates one month apart during each of the agricultural years 1998/1999 and 1999/2000. The experiments were carried out using randomized block designs, with four replica

20. Analise dialética e heterose de populações de milho-pipoca.
A diallel set of crosses among nine popcorn (Zea mays) cultivars, UNB-2, RS-20, UEM-J1, UEM-M2, CMS 42, CMS 43, Vicosa, Beija-flor and advanced generation of hybrid three-way Zelia, and their hybrid combinations was carried out to obtain heritability and heterosis estimates. The cultivars and F1s were evaluated in two crop years (1998/99 and 1999/2000) with

22. Resistance of soybean [Glycine max (L.) Merr.] to Fusarium solani f. sp. Glycines, causal agent of sudden death syndrome.
ABSTRACT: Sudden death syndrome (SDS) caused by the soilborne fungus Fusarium solani f. sp. glycine (FSG) is a major disease in soybean [Glycine max (L.) Merr.]. Slecetion for SDS resistance in the field is difficult because of the impact of the environment on disease development. The objective of my first study was to evaluate the effect of field inoculatio

23. Efeito das condicoes de colheita, pre-processamento e armazenamento na qualidade do milho-pipoca.
Com o objetivo de identificar parametros de decrescimos de qualidade de milho-pipoca, foram avaliados os efeitos dos metodos de colheita e debulha de graos, dos teores de umidade inicial, da temperatura do ar de secagem e do tempo de armazenamento sobre a capacidade de expansao das cultivares Zelia e CMS 43. A colheita foi realizada quando ambas as cultivare

24. Multivariate analyses of genotype x environment interaction of popcorn.
Os objetivos deste trabalho foram avaliar a interação genótipo x ambiente (GxA) em milho-pipoca e comparar dois métodos de análise multivariada (AMMI e GGE). Os tratamentos foram nove cultivares de milho-pipoca, plantadas em quatro épocas de semeadura em cada ano de cultivo em 1998/1999 e 1999/2000. O delineamento foi em blocos ao acaso, com quatro rep
