ABSTRACT

‘Juniper’ (Reg. No. CV-1021, PI 639951) is a hard red winter wheat (Triticum aestivum L.) developed by the Idaho Agricultural Experiment Station and released in February 2006. Juniper was tested under the experimental numbers A91013W-1 and IDO575. It is a full-stature wheat released for very low rainfall, crop-fallow rotations of the Intermountain West and was released for its improved resistance to stripe rust (Puccinia striiformis Westend) and dwarf bunt (Tilletia controversa Kühn in Rabenh) and bread-baking quality compared with current full-stature cultivars. Juniper had an average yield in rainfed trials of 3290 kg ha^–1, compared with the other tall cultivars for this region, ‘Weston’ and ‘Bonneville’, which had grain yields of 3050 and 3180 kg ha^–1, respectively. Weston has undesirable baking quality due to short dough mixing time. Juniper has nearly a full minute longer mixograph mixing time compared with Weston (p < 0.01). Juniper also has similar snow mold tolerance (causal organism Typhula spp.) to Bonneville without the undesirable characteristic of late heading date and maturity. Juniper heads 3 d earlier than Bonneville.
