Tender Details

Faba bean production in Australia is constrained by soil acidity, particularly in Western Australia, South Australia, southern New South Wales and parts of Victoria, where acidic soils reduce root growth, nodulation, nitrogen fixation, crop vigour and grain yield. Soil acidity also limits the expansion of faba bean into otherwise suitable production environments. While liming remains an important soil management practice, sub-surface acidity is often difficult, slow and costly to remediate, creating a need for complementary genetic solutions that improve crop performance and profitability on affected soils. Recent GRDC investments have successfully delivered acid-tolerant rhizobia for faba bean, improving nodulation and nitrogen fixation under low pH conditions. However, the effectiveness of these inoculants depends on successful plant-rhizobia interactions, and current elite faba bean germplasm remains poorly adapted to acid soils (pH (CaCl2) This four-year investment will accelerate the development of acid-soil-tolerant faba bean varieties by delivering the germplasm, genetic knowledge and breeding tools required to support long-term genetic improvement. The investment will identify and validate novel sources of acid soil tolerance from Australian and international germplasm, improve understanding of the physiological, biochemical and genetic mechanisms underpinning tolerance, and translate these discoveries into practical breeding outcomes for Australian faba bean breedin...
