Plant Sci. 93: 143–148. Snowstar is a hard white spring wheat (Triticum aestivum L.) that represents an improvement in end-use quality specifications of the Canada Western Hard White Spring wheat class compared with Snowbird. Snowstar was evaluated in the Central Bread Wheat Cooperative Test in 2003, and the Hard White Wheat Cooperative Test in 2004 and 2005. Snowstar appears best adapted to the longer season wheat-growing areas of the Canadian prairies. Snowstar was generally lower yielding than the check cultivars. However, in Zone 1 (Manitoba and eastern Saskatchewan), Snowstar had 2% higher grain yield than CDC Teal (2003–2005) and 1.5% more than Snowhite475 (2004–2005). In 2003 and 2005 (Zone 1), Snowstar had grain yield approximately 3% more than Snowbird (data not shown). Snowstar was resistant or moderately resistant to the prevalent races of leaf rust and stem rust. Snowstar was susceptible to common bunt and loose smut. Snowstar was generally more resistant to Fusarium head blight than the check cultivars. Snowstar had higher test weight, flour yield and whiter flour as well as stronger dough compared with Snowbird.
