New sources of resistance to leafminers (Liriomyza sativae) in melon (Cucumis melo L.) germplasm
Authors: E.F. Celin, F.I.C. Oliveira, N.S. Dias-Pini, G.H.S. Nunes and F.A.S. Arag�£o
Leafminers (Liriomyza sativae) are the main melon (Cucumis melo L.) pests in Northeast Brazil, which is the main region for the production and export of the fruit in Brazil. Of the integrated management strategies available, genetic resistance is the best method of preventing damage by these insects. The aim of this study was .. Read More»

Genetic diversity of yacon accessions using ISSR markers
Authors: R.M. Lorenzoni, F. Menine, E. Marques J�ºnior, F.L. Oliveira and T.C.B. Soares
Yacon cultivation has been intensified and the investigations of this crop have increased at the scientific, agricultural, and social levels because the roots of yacon show beneficial properties for human health, such as reducing cholesterol and glucose blood levels. Since the investigations involving yacon are very recent, th.. Read More»

Genetic structure of natural populations of Theobroma in the Juruena National Park, Mato Grosso State, Brazil
Authors: B.M. Silva, A.A.B. Rossi, J.F.E. Dardengo, C.R. Silva, I.V. Silva, M.L. Silva and C.J. Silva
Several species within the genus Theobroma have particularly high economic value, including T. cacao and T. grandiflorum. Other species in this genus, such as T. speciosum and T. subincanum, have potential value for use in the conservation of genetic diversity in breeding programs. These latter species could also be domesticated or improved to produce com.. Read More»

Industrial tomato lines: morphological properties and productivity
Authors: J.V.M. Peixoto, C. de M.S. Neto, L.F.C. Campos, W. de S. Dourado, A.P.O. Nogueira and A. dos R. Nascimento
The tomato is the second most produced vegetable in the world, with significant participation in the human diet. In addition, the production of tomatoes generates jobs and family income. The availability of improved cultivars that provide greater profitability to the producer and satisfactorily meets the needs of the fresh fru.. Read More»

Genetic variability in Melipona quinquefasciata (Hymenoptera, Apidae, Meliponini) from northeastern Brazil determined using the first internal transcribed spacer (ITS1)
Authors: J.O.P. Pereira, B.M. Freitas, D.M.M. Jorge, D.C. Torres,C.E.A. Soares and T.B. Grangeiro
Melipona quinquefasciata is a ground-nesting South American stingless bee whose geographic distribution was believed to comprise only the central and southern states of Brazil. We obtained partial sequences (about 500-570 bp) of first internal transcribed spacer (ITS1) nuclear ribosomal DNA from Melipona specimens putatively i.. Read More»

Genetic dissimilarity of putative gamma-ray-induced �Preciosa - AAAB-Pome type� banana (Musa sp) mutants based on multivariate statistical analysis
Authors: R.K.N. Pestana, E.P. Amorim, C.F. Ferreira, V.B.O. Amorim, L.S. Oliveira, C.A.S. Ledo and S.O. Silva
Bananas are among the most important fruit crops worldwide, being cultivated in more than 120 countries, mainly by small-scale producers. However, short-stature high-yielding bananas presenting good agronomic characteristics are hard to find. Consequently, wind continues to damage a great number of plantations each year, leadi..

Biometric analysis of arabica coffee grown in low potassium nutrient solution under greenhouse conditions
Authors: W.M. Moura, Y.J.B. Soares, A.T. Amaral J�ºnior, G.A. Gravina, L.D. Barili and H.D. Vieira
Genetic parameters and associations between morpho-agronomic traits and nutritional efficiencies of arabica coffee cultivars were estimated to identify promising traits to assist in the selection of coffee genotypes efficient in potassium use, under limiting conditions of this nutrient. The experiment was conducted in a greenhouse with 20 arabica coffee c.. Read More»

Genetic structure and diversity in the Dioscorea cayenensis/D. rotundata complex revealed by morphological and isozyme markers
Authors: E.A. Bressan, T. Briner Neto M.I. Zucchi R.J. Rabelloand E.A. Veasey
Of the 600 known yam species, only 10 are utilized as food, and the Dioscorea cayenensis/D. rotundata species complex is among the most cultivated. In Brazil, these species are commercially cultivated in the northeast region and are cultivated in the south and southeast regions as subsistence crops by traditional agriculturist.. Read More»

Intraspecific differentiation of Hancornia speciosa revealed by simple sequence repeat and random amplified polymorphic DNA markers
Authors: C.A. Nogueira, N.B. Stafuzza,T.P. Ribeiro, A.D.L. Prado, I.P.P. Meneze, N. Peixoto, P.J. Gon�§alves,L.M. Almeida
Hancornia speciosa, popularly known as mangabeira, is a fruit tree native to the Brazilian Cerrado that shows great economic potential, due to its multiple uses. Intraspecific classification of this species is difficult because it shows high morphological diversity. An early study of the species reported that there are six bot.. Read More»
