Abstract

‘Fieldstar’ (Reg. No. CV-1067, PI 663950) (Registration. No. 6328 by the Plant Variety Registration Office, Plant Production Division, Seed Section, Canadian Food Inspection Agency, Agriculture and Agri-Food Canada [AAFC]) hard red spring wheat (Triticum aestivum L.) was developed and released by the Cereal Research Centre of AAFC and meets the end-use quality specifications of the Canada western red spring wheat market class. Fieldstar is a partial backcross derivative of ‘McKenzie’, with ‘Clark’ as the donor of the Sm1 gene for midge resistance, which produces a product that reduces the palatability of developing seeds to wheat midge larvae (Sitodiplosis mosellana Géhin). Fieldstar is adapted to the eastern wheat growing regions of the Canadian prairies as determined by the Central Bread Wheat Cooperative Registration Test in 2004, 2005, and 2006. For registration testing, the performance of Fieldstar was estimated using the varietal blend Fieldstar VB, which consisted of 90% Fieldstar and 10% ‘Waskada’. The grain yield of Fieldstar was similar to that of the highest-yielding checks, McKenzie and ‘Superb’, and expressed resistance to leaf rust (caused by Puccinia triticina Eriks.) and stem rust (caused by P. graminis Pers.:Pers. f. sp. tritici Eriks. E. Henn.) and intermediate resistance to common bunt [caused by Tilletia tritici (Bjerk.) R. Wolff and T. laevis Kuhn in Rabenh.], loose smut [caused by Ustilago tritici (Pers.) Rostr.], and Fusarium head blight [FHB; caused by Fusarium graminearum Schwabe; teleomorph Gibberella zeae (Schwein.) Petch]. Fieldstar was released because of its combination of high yield, resistance to wheat midge, and intermediate resistance to FHB.
