Abstract

Twenty-three selected advanced spring wheat (Triticum aestivum L.) lines from Ottawa Research and Development Centre (ORDC) were compared with four known cultivars for agronomic performance at eight sites in 2016 (Ottawa CEF-C1, Ottawa CEF-C2, St. Isidore, Harrington, Palmerston, Princeville, Kincardine, Beloeil) in Eastern Canada, and for fusarium head blight (FHB). The reaction of these lines to six races of LR was determined in a growth cabinet and the LR susceptible cultivar ‘Morocco’ was included as the control for disease development in these trials. The majority of the selected lines showed no significant differences compared to four check cultivars, however ECSW05 and ECSW48, showed higher yield, moderate resistance to FHB and resistance to most of the tested LR races. Lines ECSW05 and ECSW48 will be advanced to grower’s trials in eastern Canada in 2018 and may be used as sources of resistance to LR for future cultivar development in Eastern Canada.

Highlights

Wheat (Triticum aestivum L.) is one of the worldwide staple foods in human life
The majority of the selected lines showed no significant differences compared to four check cultivars, ECSW05 and ECSW48, showed higher yield, moderate resistance to fusarium head blight (FHB) and resistance to most of the tested leaf rust (LR) races
This study was carried out at eight test sites to evaluate the performance of 23 selected advanced wheat lines for yield, test weight, thousand-kernel weight, heading date, height and protein

Summary

Introduction

Wheat (Triticum aestivum L.) is one of the worldwide staple foods in human life It accounts for almost one-third of global grain production. Grain yield is one of the most important characteristics to wheat growers and many breeding programs aim to increase wheat yield in Canada (DePauw et al 2011). Hucl and Baker (1987) found there is a correlation between crop grain yield and biological yield in those later-heading cultivars which had more kernels per spikelet, more total spikelets, and had higher grain yield. Grain protein is an important predictor of wheat yield and the optimal content is reported to be 12% to 14% as an industry standard (Darby, 2015). Löffler and Busch (1982).reported grain yield has a http://sar.ccsenet.org
