| 0 | GSHO 234 | Pre2.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Purple or red coloration of the hull (chaff) and pericarp develops during the soft dough stage of grain fill, and fades as the grain matures. Anthocyanin pigments in an acid cell solution produce the red to violet color observed in the pericarp and lemma. Inheritance: Two dominant complementary genes (Pre1 and Pre2) control purple or red pigmentation of the lemma, palea, and pericarp. Located in chromosome 2HL, about 17.1 cM distal from the vrs1 (six-rowed spike 1) locus, and over 11.2 cM proximal fro the ant2 (anthocyanin-less2) locus. Previous nomenclature and gene symbolization: Purple chaff color=P. Purple chaff color=P1. Purple pericarp=P. Purple lemma =P. Red pericarp=R. Red pericarp 2=Re2. Mutational events: Pre2.a in Buckley (NSL 32606). Mutant used for description and seed stock: Pre2.a in Buckley 3277 (GSHO 234); Pre2.b from R.I. Wolfe's Multiple Dominant Marker Stock in Bowman (PI 483237)*9 (GSHO 1926). | 1510594 | GSHO 234 |
