Authors: A.C. Maracahipes, J.W.S. Correa, P.E. Teodoro, K.L. Ara�ºjo, M.A.A. Barelli and L.G. Neves
Anthracnose is among the major diseases of the Capsicum culture. It is caused by different species of the genus Colletotrichum, which may result in major damages to the cultivation of this genus. Studies aiming to search for cultivars resistant to diseases are essential to reduce financial and agricultural losses. The objectiv.. Read More»

Identification and characterization of the bZIP transcription factor involved in zinc homeostasis in cereals
Authors: A.R. Henriques, D. da R. Farias and A. Costa de Oliveira
Members of the basic leucine zipper family, as bZIP19, are considered to be essential regulators of the adaptation to zinc deficiency. Knowing that this gene as well as its targets are conserved in the plant kingdom, we followed an in silico approach to identify and characterize the bzip19 gene in cereals. Through BLASTp in Ph..

High genetic diversity of Jatropha curcas assessed by ISSR
Authors: B.G. DÃ?Âaz, D.M. Argollo, M.C. Franco, S.M. Nucci, W.J. Siqueira, D.M. de Laat and C.A. Colombo
Jatropha curcas L. is a highly promising oilseed for sustainable production of biofuels and bio-kerosene due to its high oil content and excellent quality. However, it is a perennial and incipiently domesticated species with none stable cultivar created until now despite genetic breeding programs in progress in several countri.. Read More»

Genetic control of inflorescence in common bean
Authors: S.R. Guilherme1, M.A.P. Ramalho1, A. de F.B. Abreu2 and L.A. Pereira1
The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyze.. Read More»

Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paran�¡ State, Brazil
Authors: L.K.P. Camargo1,2, A.F. M�³gor2, J.T.V. Resende1 and P.R. Da-Silva3
The sweet potato (Ipomoea batatas L.) is a crop of great importance in developing countries, as a food staple, for animal feed, and potentially for biofuel. Development of cultivars adapted to specific regions within these countries would be useful. To start a breeding program, the first step is the establishment of a germplasm bank. We initiated a sweet .. Read More»

Evaluation of grain yield in sorghum hybrids under water stress
Authors: C.B. Menezes, D.C. Saldanha, C.V. Santos, L.C. Andrade, M.P. Mingote J�ºlio, A.F. Portugal and F.D. Tardin
Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grow.. Read More»

Strategies in identifying individuals in a segregant population of common bean and implications of genotype x environment interaction in the success of selection
Authors: M.P. Mendes, M.A.P. Ramalho and A.F.B. Abreu
The objective of this study was to compare the BLUP selection method with different selection strategies in F2:4 and assess the efficiency of this method on the early choice of the best common bean (Phaseolus vulgaris) lines. Fifty-one F2:4 progenies were produced from a cross between the CVIII8511 x RP-26 lines. A randomized .. Read More»

Multivariate analysis of backcross progeny of Passiflora L. (Passifloraceae) for pre-breeding genotype selection
Authors: C.A.F. Melo, M.M. Souza, A.G.R. Sousa, A.P. Viana and E.A. Santos
The Ward-MLM procedure was used to evaluate genetic variation in four backcross progenies and in their parents, hybrid F1 HD13 and donor parent Passiflora sublanceolata. Sixteen quantitative descriptors and five qualitative characteristics of relevance to ornamental flower production were assessed. Using the pseudo-F .. Read More»

Selection of experimental strawberry (Fragaria x ananassa) hybrids based on selection indices
Authors: S.D. Vieira, D.C. de Souza, I.A. Martins, G.H.M.R. Ribeiro, L.V. Resende, A.K.L. Ferraz, A.G. Galv�£o and J.T.V. de Resende
The strawberry (Fragaria x ananassa Dutch.), is the only vegetable belonging to the rosacea family. All strawberry species have now emerged from wild species and belong to the genus Fragaria, being that this genus presents more than 45 described species, and only 11 are considered natural species. Due to the octoploid nature o.. Read More»

Authors: J.E. Baier, J.T.V. Resende, M.V. Faria, K. Schwarz and L. Meert
Acyl sugars present in the tomato Solanum lycopersicum ‘LA-716’ accession confer good levels of resistance to arthropod pests. The objective of the present study was to select F2 plants from the interspecific cross Solanum pennellii ‘LA-716’ x Solanum lycopersicum ‘Redenção’ to assess resistance to spider .. Read More»
