Registration of ‘UI Bronze Jade’ hard white winter wheat

Abstract

‘UI Bronze Jade’ (Reg. no. CV-1160, PI 691501) hard white winter wheat (Triticum aestivum L.) was developed and released by the Idaho Agricultural Experimental Station in 2019. It was developed from the cross ‘UI Silver’(PI 658467)/IDO660 using a modified bulk breeding method and selected in F4:6 yield plots. UI Bronze Jade was tested as the experimental number A0709W-44 from 2014 to 2017 and as IDO1706 in 2018 and 2019. Compared with the known high-quality hard white check cultivar UI Silver in Idaho and in the Pacific Northwest, UI Bronze Jade had significantly higher grain yield, shorter plant height, and better resistance to stripe rust. UI Bronze Jade is adapted to irrigated and dryland production environments in southeastern Idaho and in rainfed environments in northern Idaho.
