Rice from space promises robust new varieties

space-bred seeds can be used as an early or late crop because of their adaptability.

"Because of the unusually high temperatures and severe drought this summer, diseases and insect pests were serious in some regions in the country, reducing the rice output," he said. "However, the space-bred rice showed strong drought resistance and good ability to resist pests and disease. Space rice was significantly less affected than ordinary rice."

"Space breeding is a new technology with outstanding advantages," said Dong Hualin, an expert from the provincial academy of agricultural sciences. "Space creates a special mutagenesis environment, which is difficult to achieve on Earth."

Mutagenesis is a process that leads to permanent and possibly inheritable genetic mutation.

"The high vacuum, high cleanliness, weightlessness, strong radiation, ultra-high-speed operation and magnetic wire cutting in space can greatly shorten the breeding period," he said.

Scientists expect to produce 7,125 kg per hectare this year, Gao said. Some of the rice will be used for further breeding research and some will be supplied to the markets as a high-end product costing about 200 yuan ($27.46) per kg.

So far, the company has conducted the planting experiment on more than 333 hectares of farmland in Jiangxi, Guizhou, Hunan and Shandong provinces in cooperation with local farmers.

"With the continuous improvement of people's living standards, consumers he higher requirements for food quality," said Dong, the agricultural expert. "I believe there are good prospects for the industrial development of large-scale planting of space-bred rice."
