Additional new allele of pink
scutellum1 found in Maize COOP phenotype-only collection
--Janet Day Jackson
This
report summarizes additional tests of viviparous stocks characterized only by
phenotype in the Maize Genetics COOP Stock Center collection (Jackson, MNL 74:69-70, 2000; MNL 78:66, 2004;
Jackson, MNL 81:32, 2007). This new allele was first noticed during routine
propagation of viviparous stocks.
Older stocks tend to lose the characteristic pink color of ps1 as they age in storage.
Crosses were made as follows: +/ps* X +/ps1 or +/ps1 X +/ps* and ears were scored at maturity for the pink scutellum phenotype. New designations have been assigned to these alleles and they have been placed on our current stock list. It is expected that with further sorting and allelism testing of other stocks characterized by phenotype only, additional ps1 alleles will be discovered.
