A new rapeseed variety developed by the Chinese Academy of Agricultural Sciences (CAAS) has been widely planted in Meishan City of southwest China's Sichuan Province, reporting a significant increase in yield per unit, further enhancing China's food security.
In 2024, China launched a national initiative aiming to improve per-unit yield for grain and oil crops. According to the annual statistics, the average food yield per hectare in 2024 has increased by 76.5 kilograms compared with 2023.
To further ensure domestic food security, China's "No. 1 central document" for 2025, unveiled on Sunday, reiterated the need to promote the large-scale yield improvement initiative, expand the implementation scale, and further advocate high-yield and efficient farming models. By introducing new varieties and high-density planting techniques, the rapeseed field in Meishan is among the leading models.
Compared with ordinary rapeseed plant varieties, whose best plant density is around 225,000 plants per hectare, the new variety requires a tighter row spacing from 33 to 35 centimeters to 27, thus nearly doubling the density, raising the number to 450,000.
The oil content of its seeds also reached over 50 percent, ranking among the top compared with major rapeseed varieties planted across China.
In 2024, the National Development and Reform Commission announced a new initiative to increase grain production by 50 million metric tons by 2030. Improving the per unit yield of grains and oil crops is vital to achieving the 2030 goal, while developing new varieties, and adopting new techniques, equipment, and agriculture models are critical approaches, said an expert.
"We need to increase the per unit yield, and we are capable of doing it. In view of our practical results, we should speed up efforts to sum up the experiences from the past two years of pilot projects, form a set of effective technological integration models and best practices, and transform these experiences into systematic methodologies for broader application. This will play a significant role in ensuring national food security and firmly securing China's food supply," said Zhong Yu from the Agricultural Economy Institute, CAAS.

Iran's UN ambassador Amir Saeid Iravani on Tuesday urged the UN secretary-general and the Security Council to condemn the United States for inciting violence and threatening to use force against his country.
In a letter addressed to UN Secretary-General Antonio Guterres and Somali UN ambassador Abukar Dahir Osman, who serves as the rotating president of the Security Council for January, Iravani accused U.S. President Donald Trump of openly inciting violence in Iran, citing Trump's post on social media platform Truth Social.
"This reckless statement explicitly encourages political destabilization, incites and invites violence, and threatens the sovereignty, territorial integrity, and national security of the Islamic Republic of Iran," Iravani said in the letter.
He also called on the UN secretary-general and the Security Council "to fulfill their Charter-based responsibilities by unequivocally condemning all forms of incitement to violence, threats to use force, and interference" in Iran's internal affairs by the United States.
Iran is also urging all UN member states to refrain from provocative and irresponsible statements or actions that violate the UN Charter, including the principles of sovereignty, territorial integrity and political independence of Iran, the letter said.
In a social media post on Tuesday, Iran's mission to the UN accused the U.S. of trying to stage "regime change" in the country, using sanctions, threats, engineered unrest and chaos to manufacture a pretext for military intervention.
With U.S. officials repeatedly threatening to intervene, Chief Commander of the Iranian Army Amir Hatami has stressed that the Iranian armed forces are in a state of full readiness, warning that any miscalculation by "enemies" would trigger a decisive response.
Iran's Defense Minister Aziz Nasirzadeh has also said that the country will respond forcefully to any attack and "defend the country with full force and until the last drop of blood."
The United States virtual embassy in Iran on Tuesday urged U.S. citizens to leave the country.
According to media reports on Wednesday, the U.S. is withdrawing some of its personnel from its military bases in the Middle East as a precaution amid heightened regional tensions.
Qatar has also confirmed that personnel are departing U.S. bases there over "regional tensions."
Meanwhile, media reports quoted anonymous sources saying that Iran has warned neighboring countries hosting U.S. forces that U.S. military bases could be targeted if the U.S. intervenes in the ongoing unrests.
