Stock number: BGS 595
Locus name: Anthocyanin-deficient 4
Locus symbol: ant4 Previous nomenclature and symbolization:

Exrubrum = rub (2).

Monofactorial recessive (4, 5).
Location is unknown.

Depending on the growing conditions, a slight pigmentation can be observed in the auricles, awns and lemmas of the mutant plants. The amount of anthocyanin pigmentation is clearly decreased compared to the mother varieties (3, 6). The original mutant alleles ant4.16 and ant4.17 are taller and later maturing than their mother variety Foma (3). The Bowman backcrossed derived line for ant4.16 is earlier than Bowman (1).

An ethylene imine induced mutant in Foma (CIho 11333) (3).

ant4.11, 4.16, 4.17 (NGB 114566), 4.28 (NGB 114583), 4.31 (NGB 114586) in Foma (6); ant4.32 (NGB 114587) in Foma (4); ant4.37 (NGB 114592) in Foma (6); ant4.40 (NGB 114595) in Bonus (PI 189763) (6); ant4.44 (NGB 119349) in Bonus (5); ant4.53 (NGB 111870) in Bonus (4); ant4.124 in Nordal (NGB 13680) (4).
