“…The common or semi-noble garlic varieties are adapted to the climatic conditions of southeastern Brazil and are recommended for cultivation in the State of São Paulo, due to its adaptation to the regional climatic conditions (Mota et al, 2005(Mota et al, , 2006. Moreover, they do not require vernalization and are highly productive, presenting excellent commercial quality.…”

“…A cultivar Peter Pears estava pouco desenvolvida aos 30 dias e não pode ser avaliada, mas quando ocorreu a emissão da espiga, essa cultivar tinha o maior comprimento da folha e a segunda maior largura dentre as demais cultivares, logo, essa característica é pouco estável, ocorrendo considerável variação entre as cultivares nas diferentes épocas analisadas. Mota et al (2006) trabalharam com essa característica e conseguiu diferenciar as cultivares de alho dentro do grupo seminobre, já para as cultivares do grupo nobre não foi possível a diferenciação.…”

“…Quando foi realizada uma avaliação nas cultivares no momento da emissão da espiga, o número de folhas diferenciou a cultivar Gold Field, com o maior número em relação às demais (Tabela 4). Mota et al (2006) também diferenciou cultivares de alho dentro do grupo seminobre e nobre por meio do número médio de folhas.…”

RESUMOA caracterização de cultivares de flores é fundamental nos processos de registro e proteção dessas e também na certificação da pureza genética. Nesse trabalho foram realizadas a caracterização e a certificação da pureza genética de cultivares de Gladiolus sp. por meio de marcadores morfológicos. Utilizaram-se onze cultivares de Gladiolus sp., e para a caracterização das cultivares, as parcelas foram constituídas de 25 plantas avaliando-se características dos cormos, folhas e flores. O delineamento experimental adotado foi de blocos casualizados, com quatro repetições Para a certificação da pureza genética, foram instaladas parcelas constituídas de 24 plantas e cormos contendo contaminação varietal em diferentes proporções. Foram utilizadas três cultivares para compor os tratamentos e as avaliações foram conduzidas por três avaliadores que desconheciam a porcentagem existente de contaminação varietal. Foram calculadas as porcentagens de acerto e de erro com base nos resultados obtidos nas avaliações. Foi calculado o desvio padrão da média dos resultados nas quatro repetições, obtidos pelos três avaliadores. Para verificar a significância dos desvios entre os resultados obtidos pelos avaliadores foi utilizado o teste de qui-quadrado ( 2 ). Por meio de características do cormo é possível diferenciar quatro cultivares das onze avaliadas. A característica da cor das flores é o descritor morfológico mais seguro para a diferenciação das cultivares de gladíolo. Dependendo das características das cultivares contaminantes e das cultivares em análises é possível utilizar descritores morfológicos para a certificação de pureza genética em cultivares de gladíolo.Termos para indexação: Gladiolus sp, flores, contaminação varietal. ABSTRACTThe characterization of flower cultivars is fundamental in the registration and protection processes and also in the genetic purity certification. In this work, both the characterization and the genetic purity certification of cultivars of Gladiolus sp by means of morphologic markers were made. Eleven cultivars of Gladiolus sp. were used and for the characterization of the cultivars, the plots were made up of 25 plants, evaluating the characteristics of corms, leaves and flowers. The used experimental design was the one of randomized blocks with four replicates. For the genetic purity certification, plots with 24 plants and corms containing varietal contaminations in different proportions were established. Three cultivars were used to make up the treatments, and the evaluations were conducted by three evaluators who were unaware of the existent percentage of varietal contamination. The percentage of mistakes was calculated based upon the obtained results of the evaluations. The standard deviation of the means of the results in the four replicates obtained by the three evaluators was calculated. In order to verify the significance of the deviations among the obtained results by the evaluators, Chi-square test ( 2 ) was used. By means of corm characteristics, it is possible to distinguish ...

-The objective of this work was to identify nonlinear regression models that best describe dry matter accumulation curves over time, in garlic (Allium sativum) accessions, using Bayesian and frequentist approaches. Multivariate cluster analyses were made to group similar accessions according to the estimates of the parameters with biological interpretation (β 1 and β 3 ). In order to verify if the obtained groups were equal, statistical tests were applied to assess the parameter equality of the representative curves of each group. Thirty garlic accessions were used, which are kept by the vegetable germplasm bank of Universidade Federal de Viçosa, Brazil. The logistic model was the one that fit best to data in both approaches. Parameter estimates of this model were subjected to the cluster analysis using Ward's algorithm, and the generalized Mahalanobis distance was used as a measure of dissimilarity. The optimal number of groups, according to the Mojena method, was three and four, for the frequentist and Bayesian approaches, respectively. Hypothesis tests for the parameter equality from estimated curves, for each identified group, indicated that both approaches highlight the differences between the accessions identified in the cluster analysis. Therefore, both approaches are recommended for this kind of study.
