New Zealand and China in study to improve grain production
Scientists from New Zealand and China have commenced a joint study to improve seeds which will help farmers to produce more grains for the world''s growing population.
University of Canterbury Professor, Paula Jameson, and senior research fellow, Dr. Jiancheng Song, of Yantai University, in east China''s Shandong Province, had published a paper finding the wheat genes that could be prime targets for increasing grain size and grainnumber, said a statement from the University of Canterbury.
"The beauty of wheat is that there are so many different varieties in the world. Now we have worked out what genes are important for changing hormone levels to increase grain size and number, we can use traditional breeding techniques to find the varieties of wheat that already have this feature," Jameson said in the statement.
Both Canterbury and Shandong had similar temperate climates, which would allow the wheat work to continue in China, where wheat was a main food crop and it was easier to obtain research funding for the work, she said.
Research would also continue at the University of Canterbury as the research group had been applying the knowledge to seed production.
New Zealandwas the eighth biggest exporter of vegetable seeds in the world, and the New Zealand seed industry was primarily based in the Canterbury region with exports of about US$123.18 million a year.
By 2030, the world would have an estimated two billion more people to feed.
Bread wheat made up over 20% of the world''s food supply and with increases in global population the demand for more wheat would need to be met.
Jameson said New Zealand produced a huge amount of seed for the rest of the world to grow, but most research into seeds involved characteristics that were beneficial for the end user of the seed, either the farmer who planted it or the consumer.
"No one has been looking after the farmers who produce the seed for everyone else to grow. Better yield and quality of the seed will lead to a better price for the seed farmer," she said.
Last week, the New Zealand government announced it would fund a project led by Chinese-owned agribusiness, PGG Wrightson, to improve seed and plant species for farmers, and to improve animal productivity and minimise environmental impacts.
