Combining ability of S3 progenies for key agronomic traits in popcorn: comparison of testers in top-crosses
Authors: V.J. de Lima, A.T. do Amaral Junior, S.H. Kamphorst, G.F. Pena,J.T. Leite, K.F.M. Schmitt, C. Vittorazzi, J.E. de Almeida Filho and F. Mora
The successful development of hybrid cultivars depends on the reliability of estimated combining ability of the parent lines. The objectives of this study were to assess the combining ability of partially inbred S3 families of popcorn derived from the open-pollinated variety UENF 14, via top-crosses with four testers, and to c..

Bulk segregant analysis (BSA) for improving cold stress resistance in maize using SSR markers
Authors: M.Q.U. Farooqi, K.J. Sa, T.K. Hong and J.K. Lee
In this study, eight inbred maize lines with high or low tolerance to cold temperature were investigated using bulk segregant analysis (BSA). Genetic diversity and genetic relationships were investigated using 100 simple sequence repeat (SSR) markers linked to cold tolerance in maize. A total of 319 alleles were identified. Am.. Read More»

Genetic diversity in elite inbred lines of maize and its association with heterosis
Authors: E.H. Fernandes, I. Schuster, C.A. Scapim, E.S.N. Vieira and M.M.D. Coan
The objective of the current study was to apply molecular markers (microsatellites) in the analysis of genetic diversity of 48 lines of the elite maize germplasm stored in the bank of the Cooperativa Central de Pesquisa Agrícola - Coodetec, PR, Brazil, and estimate the correlation between genetic distance and heterosis and hybrid performance from t..

Inference of genetic diversity in popcorn S3 progenies
Authors: G.F. Pena, A.T. do Amaral Jr, R.M. Ribeiro, H.C.C. Ramos,M.S.B. Boechat, J.S. Santos, G.S. Mafra, S.H. Kamphorst, V.J. de Lima, M. Vivas and G.A. de Souza Filho
Molecular markers are a useful tool for identification of complementary heterotic groups in breeding programs aimed at the production of superior hybrids, particularly for crops such as popcorn in which heterotic groups are not well-defined. The objective of the present study was to analyze the genetic diversity of 47 genotype.. Read More»

Evaluation of the genotoxic activity of dicamba and atrazine herbicides in several Mexican and South American varieties of sweetcorn (Zea mays L.)
Authors: M.S. Reynoso, C.M. Alvarez, L. De la Cruz, M.D. Escoto and J.J.G. S�¡nchez
Corn is a major crop and various herbicides are used to maximize its production, which include a dicamba-atrazine mixture. This has great advantages, but can also induce DNA damage. Genotoxic activity was assessed by comet assay following application of two concentrations of dicamba-atrazine: 1000-2000 and 2000-4000 ppm. Apical meristem leaf nuclei from 1.. Read More»

Genetic analysis of maize kernel thickness by quantitative trait locus identification
Authors: S.S. Wen, G.Q. Wen, C.M. Liao and X.H. Liu
Kernel thickness is one of the most important traits in kernel structure, and is related to yield. To ascertain its genetic information more clearly, an immortal recombinant inbred line segregation population was used to map the quantitative trait loci (QTLs) for kernel thickness. As a result, two QTLs were identified on chromosome 9; both of them had neg.. Read More»
