Rezumat

In the population of the maize haploid inducer LHI-7, an association of morphological polymorphism with polymorphism in haploid induction rate (HIR) was manifested. Differences in HIR of 4% were associated with anther coloration (yellow and purple), and differences in color intensity of the pericarp were accompanied by the same differences in HIR. The identified associations are consistent with previously obtained results on the oligogenic control of HIR. Selection based on these morphological markers has improved the population by reducing the genetic variability of HIR by 1/3 and increasing its average value by 1/8.
