| The development of homozygous breeding lines in maize may be accelerated through the use of haploids. Thus, the obtaining and prior identification of haploids generated by the haploid inducer lines is an important factor. The purpose of this study was to identify haploids by flow cytometry and to correlate the nuclear DNA content to the morphological and morphometric traits of the seeds that gave rise to them. In addition, molecular markers were used to confirm the androgenetic nature of the haploid. The seeds obtained were derived from the cross between the inbred line W23 and the commercial hybrid P30F90. Among these seeds, a group was selected, putative haploids, whose embryo was white and the pericarp purplish. This group, consisting of 330 seeds, was... |
