Genetic diversity in elite inbred lines of maize and its association with heterosis

E. H. Fernandes, Schuster, I., Scapim, C. A., Vieira, E. S. N., and Coan, M. M. D., Genetic diversity in elite inbred lines of maize and its association with heterosis, vol. 14, pp. 6509-6517, 2015.

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 the crosses among these maize lines. Forty-four random primers were used and amplification of 124 polymorphic fragments was obtained.

Heterotic groups in tropical maize germplasm by test crosses and simple sequence repeat markers

C. G. Aguiar, Schuster, I., Júnior, A. T. Amaral, Scapim, C. A., and Vieira, E. S. N., Heterotic groups in tropical maize germplasm by test crosses and simple sequence repeat markers, vol. 7, pp. 1233-1244, 2008.

The objectives of the present study were to determine heterotic groups of germplasm lines of tropical maize by test crosses and by simple sequence repeat (SSR) markers and to compare five grouping methods of heterogeneous maize. Sixteen lines of nine populations in the S5 generation were evaluated in test crosses with three testers.
