Prediction of maize single-cross performance by mixed linear models with microsatellite marker information

M. Balestre, Von Pinho, R. G., and Souza, J. C., Prediction of maize single-cross performance by mixed linear models with microsatellite marker information, vol. 9, pp. 1054-1068, 2010.

We evaluated the potential of the best linear unbiased predictor (BLUP) along with the relationship coefficient for predicting the performance of untested maize single-cross hybrids. Ninety S0:2 progenies arising from three single-cross hybrids were used. The 90 progenies were genotyped with 25 microsatellite markers, with nine markers linked to quantitative trait loci for grain yield. Based on genetic similarities, 17 partial inbred lines were selected and crossed in a partial diallel design.

Prediction of maize hybrid performance using similarity in state and similarity by descent information

D. V. Ferreira, Von Pinho, R. G., Balestre, M., and Oliveira, R. L., Prediction of maize hybrid performance using similarity in state and similarity by descent information, vol. 9, pp. 2381-2394, 2010.

We evaluated the efficiency of the best linear unbiased predictor (BLUP) and the influence of the use of similarity in state (SIS) and similarity by descent (SBD) in the prediction of untested maize hybrids. Nine inbred lines of maize were crossed using a randomized complete diallel method. These materials were genotyped with 48 microsatellite markers (SSR) associated with the QTL regions for grain yield.

Prediction of maize double-cross hybrids using the best linear unbiased prediction with microsatellite marker information

M. Balestre, Von Pinho, R. G., and Souza, J. C., Prediction of maize double-cross hybrids using the best linear unbiased prediction with microsatellite marker information, vol. 10, pp. 25-35, 2011.

We examined the usefulness of the best linear unbiased prediction associated with molecular markers for prediction of untested maize double-cross hybrids. Ten single-cross hybrids from different commercial backgrounds were crossed using a complete diallel design. These 10 single-cross hybrids were genotyped with 20 microsatellite markers.

Potential of maize single-cross hybrids for extraction of inbred lines using the mean components and mixed models with microsatellite marker information

M. Balestre, Von Pinho, R. G., Souza, J. C., and Machado, J. C., Potential of maize single-cross hybrids for extraction of inbred lines using the mean components and mixed models with microsatellite marker information, vol. 7, pp. 1106-1118, 2008.

The present study examined the importance of mean (m+a’ and d) components in the performance of single-cross hybrids for the formation of new populations and determined the contribution of the mixed model (best linear unbiased predictor of random effects, BLUP) method associated with molecular markers for the choice of crosses to obtain interpopulation hybrids. Ten single-cross commercial hybrids of different companies were used for this purpose, producing all possible double-cross hybrids through a complete diallel.

Potential use of molecular markers for prediction of genotypic values in hybrid maize performance

M. Balestre, Von Pinho, R. G., Souza, J. C., and Oliveira, R. L., Potential use of molecular markers for prediction of genotypic values in hybrid maize performance, vol. 8, pp. 1292-1306, 2009.

We evaluated the potential of genetic distances estimated by microsatellite markers for the prediction of the performance of single-cross maize hybrids. We also examined the potential of molecular markers for the prediction of genotypic values and the applicability of the Monte Carlo method for a correlation of genetic distances and grain yield. Ninety S0:2 progenies derived from three single-cross hybrids were analyzed. All 90 progenies were genotyped with 25 microsatellite markers, including nine markers linked to quantitative trait loci for grain yield.

Genotypic stability and adaptability in tropical maize based on AMMI and GGE biplot analysis

M. Balestre, Von Pinho, R. G., Souza, J. C., and Oliveira, R. L., Genotypic stability and adaptability in tropical maize based on AMMI and GGE biplot analysis, vol. 8, pp. 1311-1322, 2009.

We evaluated the phenotypic and genotypic stability and adaptability of hybrids using the additive main effect and multiplicative interaction (AMMI) and genotype x genotype-environment interaction (GGE) biplot models. Starting with 10 single-cross hybrids, a complete diallel was done, resulting in 45 double-cross hybrids that were appraised in 15 locations in Southeast, Center-West and Northeast Brazil.
