0PI 658497'LATITUDE 34'Arachis glabrata Benth. var. glabrata Texas, United States Historic2009DONATEDCultivarArachis glabrata is a rhizomatous, self-pollinated, decumbent, long-lived warm-season perennial whose propagation is primarily vegetative due to the low incidence of viable seed. It produces palatable forage of high quality for ruminant nutrition which declines only slowly with maturity and persists under clipping and grazing. On three-year old stands at Stephenville, TX, leaflets were elliptic and second to fourth leaf color was 147A on the Royal Horticultural Society color chart (London), with the average spring re-growth apical leaflet 13.1 mm wide (9.7 to 14.9 mm) and 29.2 mm long (22.3 to 38.5 mm) while basil leaflet width was 10.9 mm (8.2 to 11.0 mm) and 24.5 mm long (17.6 to 38.5 mm). Regrowth leaflets following August cutting were slightly larger, apical leaflets averaging 15.2 mm wide and 33.1 mm long and basil leaflets 12.5 by 26.7 mm. The flower standard petal (vexillum) color was 23A while the wing color was 17A. While presently available rhizoma peanut cultivars died out at Stephenville, Latitude 34 persisted with 100% plot cover during years with as little as 454 mm annual rainfall and freezing temperatures lasting up to 48 hr. Stands of latitude 34 have persisted at Stephenville when air temperatures reached -15?C and 10 cm subsoil temperatures reached 1?C as well as Gene Autry, Oklahoma near Ardmore (34? 16' 45.7N 96? 59' 26.1W). However it did not survive a winter at Stillwater, OK (36?N 96?W). Susceptible to cotton root rot (Phymatotrichum ominvorum) at Stephenville TX where circular dead zones appear in planted areas. Following adequate rainfall, surrounding plants re-colonize these circles via rhizomes, indicating field-level tolerance of the disease. The fungal pathogen Sclerotenia (Sclerotinia minor) has also been observed to attack the plants of Latitude 34 at Stephenville without permanent negative effects on the field population.1827385PI 658497
