Allelism testing of viviparous stocks with pink scutellum in the Maize Coop phenotype only collection
--Jackson, JD
This report summarizes allele testing of viviparous stocks characterized by phenotype only in the Maize Genetics Coop Stock Center collection. Some of these mutants have been found in other Coop stocks and some have been sent in by cooperators over the years. Crosses were made as follows: (+/ps*) × (+/ps1) or (+/ps1) × (+/ps*) and ears were scored at maturity for the pink scutellum phenotype. Proposed designations have been assigned to these new alleles and they have been placed on our stocklist. It is expected that with further sorting and allelism testing of viviparous stocks characterized by phenotype only, additional alleles of characterized mutants will be discovered and placed in the main collection.
