A seed can change a world.

A well -known example is that in the early 1970s, Yuan Longping’s team found a infertility plant in Hainan wild rice. After continuous joint research efforts, he successfully selected hybrid rice, providing protection for national food security.

A few days ago, a press conference held a press conference to include the “Yongxing 168964 cotton” discovered in Yongxing Island, Sansha City, Hainan Province.

How did “Yongxing 168964 cotton” be discovered? How can we rank among the “top ten” of the excellent germplasm resources nationwide? It finds what is the significance of the research and utilization of cotton germplasm resources in my country? What are the new possibilities for the development of the cotton seed industry?

Two times to break the waves

It is found that cotton resources that have important value for studying the domestication of crops

“It’s not easy to come, very precious!” On December 9, Liu Guodao, deputy dean of the Chinese Academy of Tropical Agricultural Sciences (hereinafter referred to as the Chinese Academy of thermor), held a smile on the reporter of Hainan Daily with the “Yongxing 168964 cotton” specimen, “Yongyong Xing 168964 cotton “cotton” grows on Yongxing Island, Sansha City. The plants are 1.2 meters to 1.4 meters. They are opened with yellow flowers, cotton bells are small, and cotton fibers are short. After field identification, “Yongxing 168964 cotton” is “perennial land cotton semi -wild cotton”.

This is an important gain of Liu Guo Dao and Wang Zhunian, a researcher at the Chinese Academy of Hot Sciences, and Yang Hubiao, an associate researcher, and other researchers.

“We found that the near -relationship of cotton cotton is in the flower and fruit period. The inspection team attaches great importance to it. Immediately collected the quality and multiple specimens of the storage in the warehouse, and sent the selected and prepared germ and waxy leaf specimens. The mid -term database (Anyang, Henan) is delivered to the national cotton germ resources.

The process of collecting “Yongxing 168964 cotton” did not happen overnight. As early as September last year, the Chinese Academy of thermor’s scientific research team went to Sansha after receiving relevant scientific test tasks. At that time, the wind and waves around the island were large. In the 7 -day scientific examination, they encountered a big wave on the third day.

“The big waves are taller than the people. Our group of 7 people was beaten by a big wave on the boat, and all of them were falling into the water.” In memory, Liu Guodao still had a lot of heart. Fortunately, scientific researchers have been in surgery all year round, and the experience of emergency survival in the wild is quite rich. The group of people are also familiar with water nature. Therefore, everyone pulled hands and made a circle. In the vast sea, the reefs under their feet have become their only reliance.

“We stepped on the reefs hard with our feet, swimming for less than 1 meter, and then there was another big wave, which made us more than 10 meters away.” Liu Guodao said, the kind of endlessly, the feet are not endless, and your feet are not not your feet. The sense of power of the ground makes people fear.

Fortunately, after the two big waves passed, the sea surface recovered calm.

Thirty minutes later, after a long and uneasy waiting, they were rescued and successfully landed. The scientific examiners discovered that everyone’s soles of their feet were all ground out of blood, and portable items such as shoes, mobile phones, tablets, etc. have been rolled away by big waves …

This thrilling scientific examination did not collect suitable germplasm resources. Nevertheless, the team did not give up and came to Sansha again in February this year.

Kung Fu is worthy of care. This time, the scientific research team has a new discovery. “The island resource crops are very rare. We found that the” Yongxing 168964 cotton “was extremely excited!” Yang Hubiao introduced that after collecting the resources, the team brought back to the ship for drying and made into a specimen. Geographical location, etc. are recorded in detail and accurate.

Qian Qian Qian Qian Qian Qian Qian Qian Qian, the director of the Institute of Crop Science of the Chinese Academy of Agricultural Sciences, believes that “Yongxing 168964 cotton” is a cotton resources that have important value for studying the history of crop domestication. According to preliminary research, “Yongxing 168964 cotton” dates back to the era of geography or more ancient times hundreds of years ago. This is of great significance to understand the domestic domestication history and expand genetic diversity.

“Four times the cotton has island cotton and land cotton. In our country, we found perennial land cotton and half -wild species. This is a very important discovery.” Qianqian said.

Breeding experts will carry out the research on cotton anti -saline -alkali genes for cotton

“Census collection is the first step in the protection and utilization of quality resources, and the ultimate goal is to use it again.” Liu Guodao said that “Yongxing 168964 cotton” is the same as discovering other kinds of quality resources. “Golden eyes”, “But because the Chinese Academy of thermal Sciences does not conduct cotton research, we let the resources go to the place where it can play its role, and give the two specimens to the Chinese Academy of Agricultural Sciences.”

In fact, in March 2015, by chance, Du Xiongming, director of the Cotton Research Office of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, also found a cotton that grows naturally and grows on Yongxing Island, Sansha City. Yongxing 168964 cotton “.

“Some time ago, we received specimens and seeds presented by the Chinese Academy of thermor, which enriched the important source of scientific research and materials for us.” Du Xiongming said that earlier, the cotton that they discovered was called “pipon cotton” Essence In comparison with the panton cotton materials from Dongfang City, Hainan Province and Zhanjiang City, Zhanjiang City, Guangdong Province, they discovered the uniqueness of Panton cotton on Yongxing Island in Hainan.

“Pippening cotton may originate from the Mexican coast. It spreads here through the flow of the northern equatorial ocean flow. It grows naturally in many places in Hainan in many places in Hainan. There is a wide range of genetic differentiation. “Du Xiongming said.

According to reports, land cotton is the most widely cultivated cotton variety in the world. At present, the recognized 7 land cotton half -wild cotton is distributed in Central America. “Yongxing 168964 cotton” is a perennial land cotton half -wild cotton. It is common in many islands in the south of my country. It blooms in the local four seasons and is also called “four seasons cotton”.

“At present, we are studying the origin of Panton cotton from the perspective of genomic mutation.” Du Xiongming said that this year’s team has just published “Journal of Genetics and Genomics” (“Journal of Genetics”) Announcement analyzes the papers of the forgotten land cotton species of panton cotton cotton cotton “, which specializes in the impact of the original cotton cotton species of pipon cotton on the origin of world cotton cultivation cotton. Chinese cotton evolution history.

Why do cotton breeding experts favors “Yongxing 168964 cotton” so much? Du Xiongming said that after the soil planting cotton is coerced by salt, it will cause a serious decline in cotton production. At present, the team has placed the “Yongxing 168964 cotton” seeds collected in Sanya to breed, and it is expected that it can contribute to the cultivation of new cotton -resistant cotton varieties.
