To improve yield in canola, a wider gene pool is needed. We demonstrated that seed yield can be improved in inbred as well as hybrid canola using genes from the genetically distinct oilseed yellow sarson, a related species from Asia. The knowledge gained and germplasm developed from this research can be used by breeders and researchers to develop improved canola cultivars.

Farmers value simple rules of thumb for predicting crop yields. Using 12 years of National Variety Trial data, we discovered that variation in yield of wheat and barley across southern Australia is most strongly correlated with variation in aridity index, the ratio of seasonal rainfall to seasonal potential evapotranspiration. Our finding reinforces the importance of water as the primary driver dictating grain yield in southern Australia.

CP23332Accumulation of organic carbon was limited to the surface of a duplex soil in the mixed farming zone of south-eastern Australia

Accumulation of soil organic carbon is considered beneficial to both farm productivity and the environment. Although conservation farming might make little direct contribution to soil carbon stocks, it is likely to be essential for the retention of soil carbon stores in duplex soils. Conversely, the co-retained nitrogen might have more value than the carbon stocks.

CP24053A novel Leifsonia xyli subsp. xyli quantitative LAMP-based diagnostic correlated with sugarcane ratoon stunting disease rating

Tackling with ratoon stunting disease in sugarcane is crucial for global sugar production. We developed a simple method that provides rapid and accurate way to measure levels of the bacteria that cause RSD in sugarcane plants, aiding farmers in effectively measuring disease severity. This advancement is important for safeguarding sugarcane crops, ensuring stable sugar production, and supporting economies worldwide.
