Genetic improvement of plant architecture in the common bean

V. M. P. Silva, Júnior, J. A. N. Menezes, Carneiro, P. C. S., Carneiro, J. E. S., and Cruz, C. D., Genetic improvement of plant architecture in the common bean, vol. 12, pp. 3093-3102, 2013.

Knowledge of genetic control of plant architecture in the common bean can help breeders define the most adequate breeding strategy to optimize gains. We examined genetic control of plant architecture in the common bean by means of partial diallel crosses. Fourteen bean lines were crossed under a partial diallel scheme, in which group 1 was composed of 8 erect plant lines and group 2 of 6 carioca-type grain lines.

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.
