Effects of parents and planting dates on R-nj expression in maize

Euphytica Aims and scope Submit manuscript

Summary

Two sets of diallel crosses and a study using the cultivar Cudu were conducted to determine the extent to which the expression of the R-nj allele for purple aleurone pigmentation was influenced by the color level of the pollen parent, planting date, and the maternal genotype. Neither planting date nor color level of the pollen parent substantially modified relative color expression among hybrids. Maternal parent genotype primarily determined color expression. The data indicated that R-nj color differences did not differ among reciprocal crosses used as female parents. Expression of R-nj appeared to be modified by many loci.
