The autumn wind rises, the rice fragrance. On September 19th, at the Ezhou Test Base of Wuhan University in the National Key Laboratory of Hybrid Rice, more than 130 acres of hybrid rice in early May this year had matured.

"There are more than 500 grains in this ears." In the variety display area, Zhu Renshan, a professor -level senior engineer at Wuhan University, took off a rice ears and put it in your hand carefully. The long rice stalks were full of rice grains. Later, he called the staff with a good face: "The Ezhou base can be selected and seized."

"Under this year's high temperature, it is not easy to have such achievements." Zhu Renshan told Hubei Daily all media reporters that not long ago, the red lotus -type hybrid rice Luo field system demonstration base was well -harvested, and the Ezhou base was about to start selection. kind. The red lotus -type hybrid rice "珞 Red Young 1564" and the two -series hybrid rice "Easy Two You 311" here have undergone the "roasting" of the hot summer, which verify its high temperature resistance characteristics. It is expected More than 80%, the yield per mu can reach more than 700 kilograms.

Ten years of cultivation, attacking the problem of "unable to do"

Seeds are the "chip" of agriculture, and they are the foundation of ensuring national food security. Red Lotus hybridization rice is the original scientific research achievement of Zhu Yingguo team of the late Chinese Academy of Engineering and a professor of Wuhan University. It is internationally recognized as the three major cytomy infertility types internationally recognized as hybrid rice. It has significant advantages in high temperature resistance, wide adaptability, high yield, and excellent rice quality.

At the age of 18, Zhu Renshan was under the leadership of Zhu Yingguo and embarked on the road of red lotus -type hybrid rice breeding scientific research. Today, 55 -year -old has been studying hybrid rice for nearly 40 years. Among them, a technology that had been "sentenced to death" by authoritative experts was hardly attacked by Zhu Renshan.

The production of hybrid rice requires annual species, breeding infertility systems, maintenance and recovery systems, which constitutes a mutually supportive and indispensable breeding system. However, research at that time found that during the breeding process of red lotus hybrid rice, the seeds produced were always difficult to meet the national species purity standards. Some authoritative experts have explained that this is because the red lotus -type infertility has a micro -efficiency recovery gene, which leads to the "impure" of the infertility.

With the encouragement of Zhu Yingguo, Zhu Renshan, who "do not believe in evil," launched a research on this "unable to achieve" problem.

After repeated research, Zhu Renshan discovered that the purity technology of the wild defeat could not be directly applied to the red lotus hybrid rice. During the in -depth exploration of the past ten years, he led the team to develop the unique purity technology of red lotus -type hybrid rice, and established a pro -pure reproduction system, so that the purity of the red lotus infertility system reached 99.96%. The industrialization of type hybrid rice has laid a solid foundation.

In recent years, Zhu Renshan has not only led the team to dig deep into the treasure of "Red Lotus" and achieved major breakthroughs, but also made significant progress in the development and breeding of the two series hybrid rice. The red lotus -type infertility system and two -series hybrid rice and new varieties of the brown livelill and anti -rice plague have participated in the founding of the remote sensing phenotype group learning hybrid rice precision breeding laboratory. Live production combination.

"Some colleagues once said to me, you are lucky, you have encountered the" Red Lotus "product. But as Academician Yuan Longping said, 'As long as the big direction is right, not a dead end. The other side of the light. "Along the way, Zhu Renshan's research on red lotus -type hybrid rice has always been enthusiastic." Kung Fu is worthy of care. If you do n’t think about it, do n’t do it here, how can you know if you can succeed? "

Cultivate "golden species", "Red Lotus" Xiangpiao at home and abroad

In 1972, Zhu Yingguo and researchers used Hainan Island's "Red Mang" wild rice as a mother -oriented mother -in -law to hybridize with dozens of conventional rice species. The descendants are very good, so the first generation of "Red Lotus" was born. The successful selection of red lotus hybrid rice has consolidated the foundation of the Chinese people's "full and good food".

In 2017, after Zhu Yingguo's death, Zhu Renshan inherited the mantle and continued to overcome the problem of "eating well, eating safe and healthy".

Brown live lice are the widest and most harmful pests in the production of rice in my country and other Asian countries. Zhu Renshan and the team combined with the use of molecular marking the auxiliary breeding technology and conventional breeding techniques, so that "Yi Liang You 311" obtained the excellent characteristics of anti -rice plague and anti -brown live lice. Even the risk of harvesting has solved the problem of excessive pesticides brought by the excessive use of traditional chemical agents, and the output can increase by more than 10%. In 2023, it will promote planting more than 300,000 acres in Hubei.

"Kang Rao No. 1" and "Kang Rice 2" is the first of Zhu Renshan team. It has the characteristics of high output and low cadmium absorption, which can effectively solve the current problem of cadmium pollution of rice. In addition, the newly cultivated salt -resistant red lotus rice variety "Kody You 108" will be promoted and applied in a large area of ​​saline -alkali beach. my country's existing saline -alkali land is as high as 175 million mu, accounting for about 10%of the country's total cultivated land area. If the yield of saline -alkali land is 500 kg per mu, it can create an economic value of 100 billion yuan.

Under the active advancement of Wuhan University, the scientific research cooperation of Honglian hybrid rice has expanded to countries along the “Belt and Road”. In 2019, Wuhan University and Punjabi University of Pakistan jointly established the "China -Pakistan Red Lotus Hybrid Rice Joint Research Center" and hired Zhu Renshan as the head of the center. In order to better promote the scientific research results of his hybrid rice to the country and the countries along the "Belt and Road", Professor Zhu Renshan initiated the establishment of Wuhan Yanxin Agricultural Technology Co., Ltd. Rice species demonstration base. At present, Red Lotus hybrids have been successfully registered and promoted in Pakistan, the Philippines, Indonesia, Bangladesh, Vietnam and Myanmar countries. The cumulative promotion area at home and abroad has exceeded 450 million mu, creating direct economic benefits of more than 9 billion yuan Essence "Grain safety depends on ourselves!" Zhu Renshan said, "As a science and technology worker, we have continued to innovate around the breed of hybrid rice, and have contributed to the 1.4 billion Chinese people '" stable rice bowls, eating better', and also contributed. Strive to benefit from the "Belt and Road" countries along the Belt and Road, and make new contributions to the world's grain security. "
