New rice variety for flood and drought-prone areas

HÀ NỘI — New rice seed variety which is capable of adapting to climate change has been planted in flood and drought-prone regions in north and south central provinces.

The rice seed named DCG72 has a short growth period which is suitable for intensive cultivation of three crops per year.

The seed’s growth takes about 100 days, 10-12 days shorter than other seeds, said Prof. Dr. Phạm Văn Cường, deputy director of the Vietnam National University of Agriculture, and one of the rice researchers.

This rice variety was also suitable for flood-affected areas in the north central region and drought-prone in the south central region, said Cường.

Thanks to the short growth period, the early harvest should be able to avoid drought and saline intrusion at the end of the crop, he said.

“The farmers were very satisfied with the rice variety,” he said.

Along with the shorter growth period, the new variety has a high yield of 5.4 tonnes per ha and 4.9 tonnes per ha in the winter-spring and summer-autumn crops.

In addition, the rice variety is both resistant to common diseases on rice such as blight, brown leaf hoppers and rice blast caused by fungus.

The variety was experimentally planted on total area of nearly 1,000ha in seven northern and central provinces in 2018-19.

The rice variety DCG72 was recognised as a national rice variety in decision 5098/QD-BNN dated December 31, 2019.

In recent years, Việt Nam has developed hybrid rice varieties thanks to support from the project of education and research enhancement at the Vietnam National University of Agriculture with Japan’s assistance.

Under the projects, many Vietnamese scientists were trained in Japan on breeding, physiology and cultivation techniques.

The variety DCG72 was produced under the co-operation project between Vietnam National University of Agriculture and Japan's Kyushu University.
