competitive wheat line

Catalogue: GRDC Media
Highly vigorous wheat lines have been developed which can produce up to double the biomass of commonly grown varieties by the early tillering stage, effectively shading out weeds... Increased root growth also enables the wheat to out-compete weeds for water and nutrients... The best of the competitive lines grown at Eradu yielded 3.4 tonnes per hectare, compared with 3.5t/ha for Magenta , the top yielding commercial line...

As well as providing new information about the competitive wheat lines - highly vigorous lines intended to be provided to Australian wheat breeders for inclusion in germplasm development - the trials have highlighted marked differences between existing commercial varieties in their ability to suppress weeds... Mr Newman said that although the best performing competitive wheat line did not reduce weed seeds more than Magenta in 2011, it was important to remember that lines with even greater competitiveness were coming through the genetics pipeline... Another competitive wheat line which had performed well in 2010 had been significantly affected by leaf disease in the 2011 trials, so its weed suppressing ability and yields could not be properly assessed...

The proposed project will undertake research to phenotype a high early vigour wheat population (WCD2) developed within GRDC project UA00061... In the extension phase of UA00061, it is proposed to undertake phenotyping for CA of selected lines at 3 different sites with contrasting rainfall over the next 3 growing seasons This data will provide information on the stability of the expression of CA under different environments (G x E)... The proposed project aims to determine the stability of the expression in CA in different environments (G x E) and against different weed species...
