In the season when the watermelon is listed in large quantities. Those sweet melons not only satisfy the taste buds of "eating melon", but also evoke a lot of good memories.

More than 30 years ago, in Xiaobai Village, Soochow Town, Ligong District, Ningbo City, Zhejiang Province, every family planted watermelon. At that time, in various types of watermelons, it can be said that the little white watermelon is a star melon species, which is loved by the people who eat melons.

However, due to economic benefits, land fertility, and planting techniques, Xiaobai Watermelon once disappeared from the public's sight, and its germplasm resources were almost extinct.

Now, with the joint efforts of researcher Wang Yuhong and other experts of the Ningbo Academy of Agricultural Sciences, Xiaobai Watermelon has achieved "reappearance of Dongshan" from "on the verge of trace".

Two valuable melon seedlings

Speaking of the "decline" past of Xiaobai Watermelon, Shi Qinglai, the current secretary of the party branch of Xiaobai Village. He said that for the native Ningbo people, Little White Water Water is a "old foundation" that is always unforgettable.

"Little white watermelon is small, thin, sweet and crispy. In the watermelon variety in the province at that time, its taste was definitely one of the best." Shi Qing said, but with the more market competitive foreign potato species The promotion, the little white watermelon was gradually left out, and eventually faded out of the public's vision.

Xiaobai Village

So why is the little white watermelon that is not enough to be more "challenges" of the species of melon? It turned out that although the small white watermelon at that time had good taste and nutrition, there were many "shortcomings" compared to other varieties -poor selling, too long, and relatively low yield ... In order to pursue economic benefits, the local The farmers gradually abandoned the small white watermelon and turned to plant outside potatoes.

By 2004, Xiaobai Village could not see farmers planted Xiaobai watermelon. It was also this year that after learning that the situation was learned, Wang Yuhong led his team members to Xiaobai Village and determined to save Xiaobai watermelon.

"At that time, Xiaobai Village farmers had no seeds of small white watermelon. We could only run to the mountains to touch our luck to see if we could find the remaining seedlings." Wang Yuhong said that the facts prove that their luck is still good. After looking for a few days in the mountains, they finally found two semi -wild white watermelon seedlings. At that time, everyone speculated that the two seedlings may be that the beasts had eaten the melon of farmers before, and they fell the seeds there without intention.

Wang Yuhong and his party brought two seedlings back to the Academy of Agricultural Sciences for research. However, in the study, they found that the quality of these two seedlings has been degraded, and a series of cultivation work is needed to re -obtain the "blood" pure small white watermelon germplasm resources.

The continuation of excellent "blood"

The new problem is in front of Wang Yuhong's team, how to continue the pure "blood" of the small white watermelon in the past, and save its excellent genes and make use.

After many years of defeat research and cultivation, finally, the outstanding offspring of Little White Watermelon, "Yongmi 6", was born. "Yongmi 6" not only inherited the excellent "blood" of the little white watermelon, but also was blue than blue.

Today, after the continuous improved "Yongmi 6", the selling phase is better, and the birth period has also been shortened to about the same time as the watermelon of the average plain. Not only that, it also has outstanding environmental adaptability, disease resistance, cracking resistance, fruit sitting ... plus the advantages of the original meat and crispy meat, high sugar, etc. Plain watermelon is doubled.

"Yongmi 6"

"We improved the 'Little White Watermelon' and cultivated 'Yongmi 6', which has enhanced its competitiveness in all aspects. In the past, farmers have many varieties such as early planting (8424). , Cracks and other disadvantages, unsuitable for open field cultivation. And 'Yongmi 6' has a strong environmental adaptability, and even in Gobi Beach in Ningxia, it has been widely welcomed and praised by growers in the past 2 years. "Wang Yuhong introduced the way. Essence

It is reported that at present, "Yongmi 6" has 11 districts (counties, cities), including Cixi, Xiangshan, Fenghua, Changhua, Changshan, Lin'an, Pinghu, Pan'an, Wenling, Suichang, Xinchang Wangmo in Huainan and southwestern Guizhou carried out demonstration and promotion, with a demonstration and promotion area exceeding 300 acres. "I did not expect that I could plant small white watermelon again. Thanks to the experts of the Municipal Academy of Agricultural Sciences bring us such a good variety, we also provided us with guidance. We have seen the benefits of this melon, and we will definitely bring us more More income. "Xiaobai Village farmer Wang Xiaolong said with a smile.

"Yongmi 6" in growth

In addition to the direct economic benefits, it is even more pleased that the "Yongmi No. 6" is used in the use of non -agricultural and non -graining rectification under the cultivation of the cultivated land and the main grain ship. Watermelon field diseases are improved, which improves quality. This also fully demonstrates the excellent variety value of "Yongmi 6". It also has important practical significance to keep the red line and the bottom line of food safety.

Do a good job of "core" of agriculture

During the interview, Wang Yuhong told reporters that in addition to "Yongmi 6", they will also strive to cultivate more new varieties with small white watermelon "bloodlines", gradually form a series, and establish a small white watermelon "family". At the same time, in this way, the quality resources of small white watermelon will be more powerful.

"Seeds are the 'chip' of agriculture, and the quality resources are the 'silicon wafers' in the 'chip', which is a vital foundation for agricultural development. Protecting the quality of germplasm resources is equivalent to protecting the foundation of agriculture." Wang Yuhong Said that for any place, the protection of germplasm resources is a non -simple system engineering. It has a strong public welfare orientation and has high technical requirements. It is necessary to have a group of professionals who cultivate this to do well. And their team is those who are not allowed to let them.

The reporter learned that Wang Yuhong has been in the earth for decades as a germpharic resource researcher and guardian. He not only regards himself as a science and technology worker, but also treats himself as a farmer. He always runs between the fields and the laboratory, and is committed to protecting and cultivating the varieties of good melon and vegetables to promote The melon and vegetable industry continued to develop and develop. In addition to the little white watermelon, Wang Yuhong and his team have protected many excellent varieties such as Qiu Xuexue, Yuyao mustard, Cixi vegetable melon, and Ningbo Bailou.

Not only that, as a special technology association, Wang Yuhong and his team also sent services through high -frequency "going to the countryside" to help farmers greatly improve planting technology, economic benefits, and anti -risk capabilities, leading farmers to embark on a rooted in Ningbo land The road to wealth.

Wang Yuhong (right) provides guidance for farmers.

In Ningbo, there are many agricultural science and technology cultivators like Wang Yuhong. They are also firm watches of Ningbo who have created a strong city of modern seed industry. With the joint efforts of these people, more and more Ningbo's good breeds are going to Zhejiang and even the country.

It is reported that at present, Ningbo has nearly a hundred breeding enterprises, with an annual output value of over 3.5 billion yuan; in 2021, as many as 55 new varieties determined through national registration and provincial trial (recognized).

At the same time, Ningbo Seeds Industry Enterprises have held hands with universities such as Ningbo Academy of Agricultural Sciences, Zhejiang University, and Zhejiang Wanli College Ninghai Marine Biological Seed Industry Institute to promote the accelerated development of Ningbo seed industry with major scientific and technological projects.

In the past three years, Ningbo's "Science and Technology Innovation 2025" major special special specialized in supporting 37 special specifications of the seed industry, a total of 136 million yuan in financial support.

Nowadays, the journey of Ningbo seed industry has set up a new goal -by 2025, the city's annual output value of the city has reached 6 billion yuan, forming a seed industry and derivative industrial cluster with an annual output value of 20 billion yuan.

"The inheritance of the seeds is also the inheritance of culture. It contains the local customs and cultural background in a region. I hope that more young people will join us and continue to work hard for this inheritance." Wang Yuhong said.
