Abstract:
Straw is a by-product from cereal production, which can potentially be used for bioenergy. In this study we investigated the variation in straw and grain yield among commercially grown winter wheat cultivars. In 2008 and 2009, straw and grain yields were measured in 10 cultivars in either two or three locations. Six of the cultivars were included in both 2008 and 2009. In both years, straw yield varied significantly among cultivars, ranging from 2.6 to 4.1 tons DM/hectare in 2008 and from 3.4 to 4.8 in 2009. In contrast, grain yield did not vary significantly among cultivars, with yields ranging from 7.2 to 8.3 tons DM/hectare in 2008 and from 6.8 to 8.0 in 2009. Total biomass yield did not differ significantly among cultivars in any of the two years. Across the two years, however, both grain yield, straw yield and total yield varied significantly between the six cultivars tested in both years. Cultivars with similar grain yield differed by more than 1 ton DM/hectare in straw yield, resulting in higher overall biomass yield. The results show that it is possible to choose commercially available winter wheat cultivars with significantly higher straw yield without compromising grain yield.
