Interpretive Summary: ‘UI Platinum’ hard white spring wheat was developed by the Idaho Agricultural Experiment Station and released in 2014. The initial cross of UI Platinum was made in a greenhouse in Aberdeen, ID in January 2001. UI Platinum was released for its improved grain yield and desirable bread and whole grain end-use quality in irrigated and high rainfall production areas using intensive management practices. Grain yield, end-use quality, and resistance to stripe rust of UI Platinum are better or equivalent to the three widely grown hard white spring cultivars ‘SnowCrest’ , ‘WB Idamax’ , and ‘WB Paloma’. UI Platinum is also one to two days earlier and two to three centimeters shorter than WB Idamax and WB Paloma. The University of Idaho Agricultural Experiment Station will maintain Breeder and Foundation seed of UI Platinum. This cultivar is protected under the U.S. Plant Variety Protection Title V and all seed requests should be sent to the inventor/breeder during the period of protection. Registered and certified seed production and sales will be handled by LimaGrain Cereal Seed and Lansing Grain Cooperation. Seed of this release is deposited in the National Plant Germplasm System where it will be available after the expiration of the Plant Variety Protection for research purposes, including development and commercialization of new cultivars. It is requested that appropriate recognition be made if this germplasm contributes to the development of new germplasm or cultivars.

Technical Abstract: ‘UI Platinum’ (Reg. No. CV------, PI 672533) hard white spring wheat (Triticum aestivum L.) was developed by the Idaho Agricultural Experiment Station and released in 2014. UI Platinum was derived from the cross ‘Blanca Grande’ x ‘Jerome’ and tested under experimental numbers A01178S, IDO694, and IDO694C. Blanca Grande (PI 631481) is a hard white spring wheat cultivar that was released by Resource Seeds, INC in 2002 and patented in 2003. Jerome (PI 632712) is a hard red spring wheat cultivar that was released in 2004. The initial cross of UI Platinum was made in a greenhouse in Aberdeen, ID in January 2001. UI Platinum was released for its improved grain yield and desirable bread and whole grain end-use quality in irrigated and high rainfall production areas using intensive management practices. Grain yield, end-use quality, and resistance to stripe rust (Puccinia striiformis Westend f. sp. tritici) of UI Platinum are better or equivalent to the three widely grown hard white spring cultivars ‘SnowCrest’ (PI 642376), ‘WB Idamax’ (PI 661159), and ‘WB Paloma’ (PI 659489). UI Platinum is also one to two days earlier and two to three centimeters shorter than WB Idamax and WB Paloma. The University of Idaho Agricultural Experiment Station will maintain Breeder and Foundation seed of UI Platinum. This cultivar is protected under the U.S. Plant Variety Protection Title V and all seed requests should be sent to the inventor/breeder during the period of protection. Registered and Certified seed production and sales will be handled by LimaGrain Cereal Seed and Lansing Grain Cooperation. Seed of this release is deposited in the National Plant Germplasm System where it will be available after the expiration of the Plant Variety Protection for research purposes, including development and commercialization of new cultivars. It is requested that appropriate recognition be made if this germplasm contributes to the development of new germplasm or cultivars.
