“…The general behavior of this correlation is similar to that obtained by other authors (Jaramilo, 1982;Lima Neto et al, 2003;Donato et al, 2006a). However, although this is a high magnitude and significant association, it presents a limitation as a variable to be used in harvest prediction, since it assumes the condition of response variable, as well as the bunch mass.…”

“…However, this result does not agree with Donato (2006a) and Soares (2013), who state that bunch weight and pseudostem perimeter correlation is not significant and positive, which may indicate that, regardless of pseudostem thickness, the bunch mass may have a satisfactory value. However, genotypes with higher and lower height showed, respectively, higher and lower pseudostem perimeter as well.…”

“…However, some authors do not share these same results, since those genotypes showed non-significant and positive values for the association number of leaves at harvest time and bunch yield, in both production cycles (Lima Neto et al, 2003;Donato et al, 2006a). Nevertheless, Siqueira (1984) noted significant correlations between the referred characters.…”

“…In the light of these facts, it becomes evident the importance of developing breeding programs aiming to obtain cultivars with adequate height, adapted to different ecosystems, and resistant to the main diseases and pests, as well as improving fruit quality (Donato et al, 2006a), in order to supply the increasingly demanding consumer and producer markets..…”

“…Knowledge about the association between characters is very important, especially if the selection of one of them is difficult, due to low heritability or difficult measuring and identification problems.stimates of phenotypical correlations involving production bananas, yield components and other important characters in bananas can be found in several articles Donato et al, 2006a;Lima Neto et al, 2003;Soares et al, 2012;Tenkouano et al, 2002). However, for same character, it can be identified the estimate of positive, negative or null values.…”

This research aims to estimate correlations between agronomic traits and yield in Pome bananas, contributing to the elaboration of models for estimation of harvest. Agronomic traits were evaluated in 98 plants of 'Dwarf Prata' and 96 'BRS Platina', considered replicates and sampled at random. Correlations between the masses of the bunch, and hands and plant height; pseudostem perimeter at ground level, at 30 cm and at 100 cm in height; number of green leaves; mass of the bunch; number of hands and fruits per bunch; mass of the hands; mass, length and diameter of the stem, and mass of the fruit of the external row from the first to the tenth hand were estimated. The highest correlation coefficient between yield and vegetative traits for 'Dwarf Prata' and 'BRS Platina', was obtained for pseudostem perimeter at ground level, indicating its greater potential to compose harvest estimation models. The correlations between the masses of the bunch and hands with yield traits, for both genotypes, showed a higher potential for predicting the number of hands and fruits. Appropriate correlation estimates are associated with the fourth and fifth bunch, for the 'Dwarf Prata' and 'BRS Platina', respectively, using the mass of the fruit of the external row.

Diversidade genética, crescimento e produção de genótipos de bananeira 'Prata-Anã' em área com mal do panamá

resumo -No perímetro irrigado do Jaíba, no norte de Minas Gerais, existem relatos sobre a presença de alguns genótipos de banana'Prata-Anã' supostamente tolerantes ao mal-do-panamá, nos quais a doença não se estabeleceu após 15 anos de cultivo, mesmo na presença do patógeno. Portanto, objetivou-se avaliar a diversidade genética, o desempenho agronômico e o comportamento dos clones da bananeira'PrataAnã' cultivada em área com histórico do mal-do-panamá. Foram coletados vinte e quatro genótipos, 11 caracterizados no momento da coleta como doentes (GEN 1, GEN 2, GEN 3, GEN 4, GEN 5, GEN 6, GEN 7, GEN 8, GEN 9, GEN 10 e GEN 11) e 13 aparentemente sadios (GEN 12, GEN 13, GEN 14, GEN 15, GEN 16, GEN 17, GEN 18, GEN 19, GEN 20, GEN 21, GEN 22, GEN 23 e GEN 24). Estes materiais foram multiplicados em laboratório de cultura de tecidos e levados para plantio na área experimental. Foram avaliados 24 tratamentos (clones de bananeira 'Prata-Anã'), no delineamento em blocos casualizados, com três repetições, 20 plantas por parcela e as seis centrais consideradas como área útil. Avaliaram-se, além da diversidade genética, comprimento e diâmetro do pseudocaule, número de folhas, massa do cacho, das pencas e do engaço, número de pencas e de frutos, comprimento e perímetro do fruto central da segunda penca, porcentagem de plantas mortas, incidência e severidade do mal-do-panamá. A distância genética média entre os clones foi de 43,5%, variando de 11,8% a 85%. Os indivíduos GEN 12, GEN 13, GEN 19 e GEN 22 apresentam maiores diâmetros do pseudocaule ao nível do solo e a 30 cm, e foram mais altos. Os indivíduos GEN 13, GEN 17 e GEN 19 destacaram-se, nos dois ciclos de produção, como tolerantes ao mal-do-panamá. termos para indexação: Musa spp.,caracteres agronômicos, Fusarium oxysporum f. sp.

Prata-Anã supposedly tolerant to the Panama disease, where the disease was not established after 15 years of cultivation even in the presence of the pathogen. Therefore this study aimed to evaluate the genetic diversity, agronomic performance and behavior of genotypes of banana 'Prata-Anã' cultivated in area with a history of Panama disease. Twenty-four families were collected, 11 classified in the moment of the collection as diseased (GEN 1, GEN 2, GEN 3, GEN 4, GEN 5, GEN 6, GEN 7, GEN 8, GEN 9, GEN 10 and GEN 11), and 13 apparently healthy (GEN 12, GEN 13, GEN 14, GEN 15, GEN 16, GEN 17, GEN 18, GEN 19, GEN 20, GEN 21, GEN 22, GEN 23 and GEN 24). This material were multiplied in tissue culture laboratory and taken to planting at the experimental area. Twenty-four treatments were evaluated (clones of banana 'Prata-Anã'), in a randomized block design with three replications, 20 plants per plot and the central six in useful area. In addition to the genetic diversity, length and diameter of pseudostem, ...

The use of cover crops species may be an important strategy in the pursuit of sustainability of agroecosystems, considering benefits to soil, such as improvements of physical and chemical characteristics, and weed control. The objective of this study was to evaluate the effect of winter cover crops and other soil managements on chemical soil properties, on the cycle, on the production of the first cycle and on the fruit quality of banana cv. Nanicão Jangada in Andirá – PR, Brazil. The experiment was carried out in a commercial. Planting of banana suckers from the grower area occurred in the first half of March 2011, with a spacing of 2.40 m between rows and 1.90 m between plants. The experiment was designed in randomized blocks with four replications and six plants per plot. The six treatments were: black oat (Avenastrigosa Schreb), forage turnip (Raphanus sativus L. var. oleiferus), consortium of black oat and forage turnip, chicken litter, residues of banana plants, and bare ground. The evaluations were vegetative development and life cycle of banana plants, yield and quality of fruits, soil chemical characterstics, and fresh and dry mass of green manures. The results were submitted to ANOVA (F Test), and Tukey test at 5 % probability. Black oat and black oat with forage turnip consortium were superior in biomass production. Systems of soil management had no effect on the variables, except in the periods between planting and flowering and between planting and harvest, which were shorter in the treatment of soil management with crop residues, longer in the treatment with forage turnip, and intermediate in the other treatments.
