| 0 | PI 678795 | 'Silver River' | Melilotus albus Medik. | Texas, United States | PVPO | | Not Available | 2016 | DEVELOPED | | | | | | Cultivar | 1Silver River' (Reg. no. CV-__ , Pl ) is a rust resistant cultivar of white-flowered, annual sweetclover (Melilotus albus Medik.) adapted to south and central Texas. Sweetclover rust (Uromyces striatus Schroet.) causes a range of plant disease symptoms, including leaf drop, reduced seed and forage yield, and premature plant death. The breeding and evaluation of Silver River for rust resistance was conducted at Beeville, TX under severe epiphytotics of sweetclover rust. Two cycles of mass selection at Beeville were used to improve the rust resistance of a sweetclover plant introduction line from Uruguay. The original plant introduction population had 21 % rust resistant plants. Silver River averaged 91 % resistant plants at Beeville in 2014 and 2015, compared to 1Hubam' with a 2-year average of 7% resistance. | 1943030 | PI 678795 |
