Noor hard red spring wheat

Abstract

Noor hard red spring wheat (Triticum aestivum L.) was developed using a modified bulk breeding method at the University of Alberta, Edmonton, AB Canada. Noor is an apically awnletted, hollow-stemmed line with a combination of high yield potential, good lodging tolerance, and medium maturity. During the three years (2016–2018) of evaluation in the Parkland Wheat Cooperative test, Noor yielded 12% higher than the mean of all the checks and matured similarly to Carberry and Glenn, but 3.1 and 2.6 d later than AC Splendor and Parata, respectively. Noor was 94.9 cm tall, shorter than AC Splendor (98.4 cm), similar in height to Glenn (94.0 cm) and Parata (93.5 cm), but taller than Carberry (86.0 cm). The lodging score of Noor (2.1) was lower than Parata (3.0) and AC Splendor (3.0), but similar to Carberry (2.3) and Glenn (2.1). The test weight (kg·hL−1) of Noor (80.0) was higher than AC Splendor (78.6), similar to Carberry (80.2) and Parata (80.4), but lower than Glenn (82.2). Grain weight (35 g) and NIR protein of Noor (14.1%) was lower than all the checks. Overall, Noor was rated resistant (R) to the prevalent races of leaf, stem, and stripe rusts during the three years of testing. Noor was rated intermediate (I) to common bunt and Fusarium head blight. Three years of end-use quality evaluation indicated that Noor is acceptable for the Canada Western Red Spring class, with fewer flags.
