The objective of this work was to estimate the genetic diversity of improved banana diploids using data from quantitative analysis and from simple sequence repeats (SSR) marker, simultaneously. The experiment was carried out with 33 diploids, in an augmented block design with 30 regular treatments and three common ones. Eighteen agronomic characteristics and 20 SSR primers were used. The agronomic characteristics and the SSR were analyzed simultaneously by the Ward-MLM, cluster, and IML procedures. The Ward clustering method considered the combined matrix obtained by the Gower algorithm. The Ward-MLM procedure identified three ideal groups (G1, G2, and G3) based on pseudo-F and pseudo-t² statistics. The dendrogram showed relative similarity between the G1...

Caracterização morfológica e molecular de genótipos de mangaba
Provedor de dados: Revista Brasileira de Fruticultura
Autores: Silva,Simone Alves; Cruz,Elizangela Mércia de Oliveira; Reis,Ronaldo Viana dos; Ferreira,Claudia Fortes; Passos,Adriana Rodrigues.
O objetivo do trabalho foi verificar a divergência genética entre 25 genótipos de mangaba da região de Iramaia-Chapada Diamantina-Bahia, utilizando os marcadores morfológicos e os marcadores RAPD. As seguintes aferições foram realizadas nos frutos maduros: diâmetro longitudinal (DL) e transversal (DT), massas do fruto (MF), da semente (MS) e da polpa (MP), rendimento de polpa (%P) e a contagem do número de sementes (NS). Os caracteres químicos avaliados no fruto maduro foram: pH, acidez (Ac), sólidos solúveis totais (SST), ácido ascórbico (AA), açúcar total (ACT) açúcar redutor (ACR), açúcar não redutor (ACNR) e relação sólidos solúveis totais: acidez (SST/Ac). Para a amplificação, foram testados 51 random primers. Os resultados médios das aferições foram:...

Sources of black Sigatoka resistance in wild banana diploids
Provedor de dados: Revista Brasileira de Fruticultura
Autores: Nascimento,Fernanda dos Santos; Sousa,Yan Moreira; Rocha,Anelita de Jesus; Ferreira,Claudia Fortes; Haddad,Fernando; Amorim,Edson Perito.
Abstract  Black Sigatoka (black leaf streak disease) is caused by the fungus Mycosphaerella fijiensisMorelet. This phytopathogen colonizes banana leaves, resulting in reduced photosynthesis and decreased productivity. Fungicide applications are useful to control black Sigatoka; however, they increase production costs and can have adverse environmental and health impacts. The cultivation of resistant cultivars is regarded as a more economically viable option. The objective of this study was to perform diploid phenotyping in a set of wild banana accessions to identify resistant genotypes. A total of 31 accessions (30 with AA genome and one with AB genome) were phenotyped based on the presence of disease symptoms using a scoring scale. The area under the...

Initial horticultural performance of nine ‘Persian’ lime selections grafted onto Swingle citrumelo
Provedor de dados: Scientia Agricola

ABSTRACT ‘Persian’ lime (PL) [Citrus latifolia (Yu. Tanaka) Tanaka] is an important species both for domestic fresh fruit consumption in Brazil as well as the export market, since the country is one of the largest producers in the world despite the fact that, in commercial plantations, it is still not uncommon to find trees with low productivity and high plant vigor of unknown origin. Selections of Persian lime ‘CNPMF–2000’, ‘CNPMF–2001’, ‘CNPMF–01’, ‘CNPMF–02’, ‘IAC–5’, ‘IAC–5.1’, ‘Bearss’, ‘Persian–58’, and ‘5059’, were therefore grafted onto Swingle citrumelo [C. paradisi Macfad. cv. Duncan × Poncirus trifoliata (L.) Raf.] rootstocks and evaluated in Cruz das Almas, Bahia, Brazil in a field experiment conducted in a completely randomized block design...
