R.  aAndrogenetic haploid and SSR markers as tools for the development of tropical maize hybrids.h[electronic resource]  c2007  aThe traditional process of obtaining maize hybrids involves the generation of inbred lines through successive generations of selfing and subsequent testcrosses in order to identify the best combining ability by allelic complementation. A fast alternative to obtain inbred lines is to induce the formation of haploids followed by chromosome doubling. However, even with the aid of haploid-inducing genetic sources, this strategy has not been widely used in maize breeding programs, partly due to difficulties inherent to haploid generation and identification. In order to evaluate the possibility of using dihaploids to generate homozygous maize tropical lines, we used the androgenetic haploid inducer line W23 as a female parent in crosses with the tropical single-cross hybrid BRS1O1O.  aZea Mays  aAndrogenetic haploid  aIndeterminate gametophyte  aMicrosatellite1 aGUIMARAES, C.
