| 0 | PI 594917 | P29 | Triticum aestivum L. subsp. aestivum | Indiana, United States | NSGC |  | | 1996 | DEVELOPED | 1996 | | 40.42586860, -86.90806550 | | | Breeding material | P29 is a chromosome substitution line, resistant to barley yellow dwarf viruses (BYDV) strains P-PAV and MAV conditioned by a gene(s) on a chromosome from Thinopyrum intermedium that replaced chromosome 7D. Substitution determined by chromosome pairing and RFLP analyses. Similar to commercial wheat cultivars in yield. In a replicated trial, grain yield was 3551 kg/ha compared to 3591 kg/ha of Caldwell check, indicating no yield disadvantage of the alien chromosome substitution. Cold tolerance similar to Caldwell, awnless, 9 cm taller and 5 d later than Caldwell. Resistant to Puccinia recondita, susceptible to Erysiphe graminis common in Indiana, and susceptible to Hessian fly biotype L. | 1522127 | PI 594917 |
