Broadening environmental adaptation of soybean in Australia

Breeding resources for soybean in Australia are limited compared with more widely grown crops and there has been strategic interest in broadening the environmental range of individual varieties. Breeding efforts to improve adaptation across regions and seasons are focused on the use of the long-juvenile trait to develop short duration, less photosensitive cultivars and backcrossing the trait into temperate cultivars for (sub)tropical adaptation. Current research is exploring possibilities of molecular markers to help select potentially drought tolerant genotypes combining strong expression of three physiological traits. Saturated soil culture technique has been adapted to enable rice-soybean intercrops using a bed-furrow system in lowland rice areas in south-east Asia.
