Establishment and optimization of ISSR and SAMPL molecular markers as a tool for breeding programs of Pinus radiata

Pinus radiata is a conifer of recognized economic value. Studies at genetic and molecular level to support breeding programs of radiata pine have been conducted with difficulty due to its large and complex genome. The development of molecular markers has allowed performing studies on genetic variati...
