abstract = {Many rainfed wheat production systems are reliant on stored
soil water for some or all of their water inputs. Selection
and breeding for root traits could result in a yield
benefit; however, breeding for root traits has traditionally
been avoided due to the difficulty of phenotyping mature
root systems, limited understanding of root system
development and function, and the strong influence of
environmental conditions on the phenotype of the mature root
system. This paper outlines an international field selection
program for beneficial root traits at maturity using soil
coring in India and Australia. In the rainfed areas of
India, wheat is sown at the end of the monsoon into hot
soils with a quickly receding soil water profile; in season
water inputs are minimal. We hypothesised that wheat
selected and bred for high yield under these conditions
would have deep, vigorous root systems, allowing them to
access and utilise the stored soil water at depth around
anthesis and grain-filling when surface layers were dry. The
Indian trials resulted in 49 lines being sent to Australia
for phenotyping. These lines were ranked against 41 high
yielding Australian lines. Variation was observed for deep
root traits e.g. in eastern Australia in 2012, maximum depth
ranged from 118.8 to 146.3 cm. There was significant
variation for root traits between sites and years, however,
several Indian genotypes were identified that consistently
ranked highly across sites and years for deep rooting
traits.},
