Summary

Mutational and recombinational analyses carried out with the R-nj allele in maize to elucidate the genetic mechanism involved in unique pattern formation and origin of occasional self-coloured kernels in this stock revealed that R-nj represents a complex with two closely linked discrete components. The self-colour (Sc) component is responsible for anthocyanin production and the navajo (Nj) component regulates the time of onset and termination of pigment synthesis restricting the pigmentation to the crown region of the kernel. The probable gene order in the R region of the R-nj:Illinois isolate is: G-Sc-Nj-K.
