Selection
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»

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»

Integrated statistical learning of metabolic ion mobility spectrometry profiles for pulmonary disease identification
Authors: A.-C. Hauschild J.I. Baumbach J. Baumbach
Exhaled air carries information on human health status. Ion mobility spectrometers combined with a multi-capillary column (MCC/IMS) is a well-known technology for detecting volatile organic compounds (VOCs) within human breath. This technique is relatively inexpensive, robust and easy to use in every day practice. However, the potential of this methodolog.. Read More»

Insight into gene evolution within Cervidae and Bovidae through genetic variation in MHC-DQA in the black muntjac (Muntiacus crinifrons)
Authors: H.-L. Wu C.-C. Tong E. Li T.-L. Luo
The critical role that the major histocompatibility complex plays in the immune recognition of parasites and pathogens makes its evolutionary dynamics exceptionally relevant to ecology, population biology, and conservation studies. The black muntjac is a rare deer endemic to a small mountainous region in eastern China. We found that this species has two D.. Read More»

Identification of markers tightly linked to tomato yellow leaf curl disease and root-knot nematode resistance by multiplex PCR
Authors: S.X. Chen J.N. Du L.N. Hao C.Y. Wang Q. Chen Y.X. Chang
Seven different commercial F1 hybrids and two F2 populations were evaluated by multiplex PCR to identify plants that are homozygous or heterozygous for Ty-1 and Mi, which confer resistance to tomato yellow leaf curl disease and root-knot nematode, respectively. The Ty-1 and Mi markers were amplified by PCR and identified by digestion of the amplicons with th.. Read More»

Path analysis of the energy density of wood in eucalyptus clones
Authors: A.M. Couto, P.E. Teodoro, P.F. Trugilho
Path analysis has been used for establishing selection criteria in genetic breeding programs for several crops. However, it has not been used in eucalyptus breeding programs yet. In the present study, we aimed to identify the wood technology traits that could be used as the criteria for direct and indirect selection of eucalyp.. Read More»

Multivariate diallel analysis allows multiple gains in segregating populations for agronomic traits in Jatropha.
Authors: P.E. Teodoro, E.V. Rodrigues, L.A. Peixoto, L.A. Silva, B.G. Laviola, L.L. Bhering
Jatropha is research target worldwide aimed at large-scale oil production for biodiesel and bio-kerosene. Its production potential is among 1200 and 1500 kg/ha of oil after the 4th year. This study aimed to estimate combining ability of Jatropha genotypes by multivariate diallel analysis to select parents and crosses that allo.. Read More»

Selection pressures have driven population differentiation of domesticated and wild common carp (Cyprinus carpio L.)
Authors: L.H. Xu C.H. Wang J. Wang Z.J. Dong Y.Q. Ma X.X. Yang
Selection pressures are the principle evolutionary forces for the genetic differentiation of populations. Recent changes in selection pressures on mitochondrial DNA and microsatellite have been described in a wide variety of organisms. The common carp (Cyprinus carpio) has experienced strong selection pressure, in particular artificial selection, during i.. Read More»

Full-sib reciprocal recurrent selection in the maize populations Cimmyt and Piran�£o
Authors: K.S. da Cunha M.G. Pereira L.S.A. Gon�§alves A.P.C.G. Berilli E.C. de Oliveira H.C.C. Ramos A.T. do Amaral J�ºnior
We estimated the genetic gains of the 12th cycle of reciprocal recurrent selection for maize traits of agronomic interest. We used 23 ISSR molecular markers in an attempt to maximize genetic variability among and within populations based on selection of S1 progenies. To this end, 138 full-sib families were evaluated in a randomized block design in two enviro.. Read More»

Regularized quantile regression applied to genome-enabled prediction of quantitative traits
Authors: M. Nascimento, F.F. e Silva, M.D.V. de Resende, C.D. Cruz,A.C.C. Nascimento, J.M.S. Viana, C.F. Azevedo, L.M.A. Barroso
Genomic selection (GS) is a variant of marker-assisted selection, in which genetic markers covering the whole genome predict individual genetic merits for breeding. GS increases the accuracy of breeding values (BV) prediction. Although a variety of statistical models have been proposed to estimate BV in GS, few methodologies h.. Read More»
