Accession details

The M1 generation was grown in the 2004/05 Puerto Rico nursery, where approximately 700 M1 panicles were taken. Twenty seeds from each M1 panicle were planted panicle-to-row in the M2 generation, at a single seed per hill, in hills spaced 30 cm apart, in 30 cm wide rows. The albino mutant was found a single M2 row segregating 10 green: 4 albino plants. In subsequent testing in the greenhouse of the 10 surviving plants, 3 heterozygous families were identified which segregated 95 normal: 29 albino, a satisfactory fit to a single recessive gene ratio (0.50 less than P less than 0.75). Residual seeds from the 3 heterozygous M2 plants were composited to provide a genetic stock which will segregate 3 normal: 1 mutant.
