Problem:

Traditional rice farming is heavily reliant on ready supplies of water and labour. Climate change and urbanisation, however, threaten traditional paddy cultivation.

Solution:

A team led by plant development biologist Dr Smita Kurup at the Rothamstead Research in collaboration with the International Rice Research Institute (IRRI), based in the Philippines, and Punjab Agricultural University, India, are using use cutting edge plant breeding technologies, field trials and an image based system for measuring traits to accelerate the development of new direct seeded rice (DSR) adapted rice varieties that can be grown with less water than conventional puddled transplanted rice.

In many parts of Asia farmers are switching to direct seeded rice DSR as a more sustainable alternative. This is grown in dry fields, so uses less water and requires less work. It also cuts out the greenhouse gases that bacteria in paddy fields produce.

Kurup has already identified in the lab hitherto ‘unknown’ varieties more suitable to DSR in terms of their seedling traits by screening several hundred varieties from the International Rice Genebank at IRRI.

As a next step, the plan is to use these lines to combine with current good yielding and disease resistant rice cultivars to generate new high-yielding “DSR adapted” rice varieties.
Once developed, their field performance will be evaluated at multiple locations. Finally, the most promising breeding lines will be nominated for trails in Asia before releasing to farmers.
