The new japonica hybrid rice variety passed the foreign examination and approval for the first time

Recently, the reporter learned from the Department of Science and Technology of Hubei Province that the hybrid rice japonica 202/181 selected by the rice breeding team led by You Aiqing, a researcher of the Hubei Academy of Agricultural Sciences, passed the examination and approval
in the Republic of Burundi.
This is the first japonica hybrid rice variety
approved by foreign countries in China.

Burundi is located on the southern side of the equator in central and eastern Africa, with an average altitude of 1,600 meters, and 70% of the country's income comes from agriculture, and rice is the main food crop
in Burundi.
The seed purity of its original rice varieties is not high, and there are problems such as
uneven plant height, weak stem, poor disease resistance and low yield.

The new varieties selected by You Aiqing's team adopt the breeding technology combining molecular marker screening and anthher culture, which has the advantages of high yield, cold tolerance, resistance to rice blast and white leaf blight, etc.
, and performs well in multi-point demonstrations in high-altitude areas of Yunnan, with mu yield of more than 800 kg, and an altitude of up to 1850 meters
suitable for promotion and planting.

After layers of screening by the Chinese senior agricultural expert group in Burundi, hybrid rice japonica 202/181 entered the high-altitude area of Burundi for experimental planting, and the experiments showed that it could increase the yield by more than 200 kg per mu compared with the local main cultivars, and the yield was almost doubled, and the potential for increasing yield was huge, which attracted the attention
of the local government.

Hybrid Rice Japonica 202/181 is a breakthrough made with long-term funding from the Hubei Provincial Science and Technology Department's major special project for technological innovation and key research and development programs
.
The research of two-line hybrid rice originated in Hubei, and the Hubei Academy of Agricultural Sciences has long adhered to the research on breeding of two-line japonica hybrid rice, and has bred China's first two-line japonica hybrid variety Ejaponica No.

It is reported that after the approval of hybrid rice japonica 202/181, it will be widely promoted and applied in Burundi, which can effectively solve the bottleneck problems such as low local rice yield and low ability to withstand natural disasters, provide Chinese solutions to solve the problem of food shortage in developing countries, and make greater contributions
to world food security.
