Ceres has advanced the testing of its biotech sugarcane traits to the next stage ahead of schedule due to positive data from initial field evaluations under tropical conditions in Latin America. Leading product candidates are currently being multiplied for wider-scale field evaluations which are scheduled to begin in May and June 2015.
Ceres reported that its yield traits accelerated growth and increased biomass in elite tropical sugarcane varieties. In addition, plants with one of the company’s drought tolerance traits maintained biomass yields under low water conditions, and in certain cases, maintained yields with as little as half the water normally required during production. Field evaluations represent a critical stage in the development of biotech crop traits, as they provide greater insight into how traits may perform in an agricultural setting.
Roger Pennell, PhD, vice president of trait development for Ceres, said that sugarcane industry researchers who completed the study on behalf of Ceres accelerated their first stage of field trialing ahead of the completion of the first growing cycle in order to expand the scale of the evaluations.

Pennell said that faster growth, higher yield and greater resilience to drought and other stress conditions would not only increase output, but also lower production costs for the industry. Such traits could potentially increase the number of harvests during the lifetime of a sugarcane stand, extend the growing season and expand the area where economically attractive yields can be achieved he suggested.
Favorable results from a research setting are not a guarantee of future commercial performance, and further evaluations will be necessary to confirm these results. The next stage of research field trials, which will provide more definitive results, is expected to be completed by June 2016. At the current pace, commercial sugarcane cultivars with Ceres' traits could be ready for commercial scale-up as early as 2018.
According to the UN Food and Agriculture Organization, 65 million acres (26 million hectares) of sugarcane were harvested worldwide in 2013, including 32 million acres (13 million hectares) in Latin America.
