The marketization of scientific research centers for species of enterprises is refreshing.

Original title: scientific Research Center: new Standard equipment for kinds of Enterprises

The raspberry industrial park in Nanhe County, Hebei Province covers an area of more than 2700 mu. The industrial park integrates raspberry cultivation, planting, R & D and sales, and has a standardized tissue culture room of more than 4000 square meters. 15 million raspberry seedlings can be cultivated every year, and more than 300 farmers are on the road to prosperity by planting raspberries.

Comprehensive report of "three Rural Express": laboratories, breeding stations, experimental plots. More and more of these breeding research sites are becoming the "standard allocation" of seed enterprises. What is the standard configuration? How do researchers work in seed enterprises? Is it any different from scientific research institutes?

Recently, the editorial department of Modern seed Industry Weekly specially invited several observers to enter the breeding R & D center of seed enterprises to "work" with "in-enterprise" researchers for a day to bring this group of "seed enterprise laboratory logs."

Seedling tissue culture laboratory--

New products of cauliflower breeding in "bad" environment

In the seedling tissue culture laboratory in Tianjin, Ji Heliang and his assistant are busily observing the progress of tissue culture seedlings of new varieties of cauliflower-the neat rows of tissue culture bottles on the cultivation shelf and all kinds of equipment in the laboratory are refreshing.

At present, the cultivated seed industry is beginning to cultivate a new variety of cauliflower with stronger adaptability and better quality than imported varieties-- loose cauliflower. Now that we have entered the demonstration planting stage, we will be able to bring the seeds to the market in the near future. As the head of the company, Ji Heliang has recently devoted almost all his energies to the laboratory.

In recent years, the market demand of cauliflower is constantly changing. the loose cauliflower is deeply loved by consumers for its tender green pedicel and crisp sweet quality. Flower ball loose cauliflower, also known as "organic cauliflower". This "organic", not that organic. The so-called "organic cauliflower" is only a variety of cauliflower, which does not necessarily refer to cauliflower grown by organic methods, but because its place of origin is very superior and can achieve the quality of organic food, it is called "organic cauliflower". Compared with ordinary cauliflower, this kind of cauliflower has slender stems, loose flowers, looks like a bouquet of flowers, and has a popular taste.

"it is very easy to grow loose cauliflower, but the breeding stage is more difficult." Ji Heliang said: recently, Tianjin's cultivated seed industry has focused on cruciferous vegetables, done enough articles on improving seed quality, and carefully cultivated loose cauliflower.

In order to collect raw materials that are more suitable for tissue culture seedlings and constantly domesticate them, Ji Heliang went to various parts of the south many times to look for them. "since it is breeding, it is necessary to see more, go far, choose the best from the best, and select the pure from the fine. in order to cultivate excellent varieties better and better."

After unremitting efforts, the raw material of loose cauliflower was finally found by Ji Heliang. In the process of cultivation, because the survival rate of tissue culture seedlings is not very high, Ji Nuoliang is more cautious. Every time he makes tissue culture seedlings, Ji Heliang personally goes to the laboratory to supervise and guide. "sometimes, if you don't know why, the tissue culture seedlings are contaminated. The stems and leaves of the culture medium and raw materials must be aseptic, but even so, there is no 100% guarantee of success, as long as those who can survive are the best tissue culture seedlings. "

In the tissue culture laboratory, the author personally experienced every process of making tissue culture seedlings. One staff member meticulously cut off the bouquet of the raw materials, and then removed the buds from the bulb, while another staff member cut the short stem of the bulb into small pieces of more than 1 centimeter and carried out aseptic treatment. all cauliflower are carefully planted in the cultivation bottle, unified into the medium for cultivation. "the temperature of tissue culture seedlings is 21 ℃ to 25 ℃, and the light is usually 14 to 16 hours. If you miss the planting season, it doesn't matter. Let the tissue culture seedlings grow in the bottle all the time. After the seedlings grow, they will be cut, and the culture medium will be changed. The complete tissue culture seedlings can grow in the ground. " Ji Heliang said.

The scientific and technological support of the laboratory provides a solid foundation for the cultivation of new varieties of cauliflower. Ji Heliang said that the main direction of breeding is to surpass the original varieties, but new varieties must have wide adaptability. Rely on the laboratory to simulate the harsh environment, let the seedlings produce variation, can derive new germplasm resources. Each cultivation bottle is marked with different letters and numbers to distinguish the batch and time of breeding seedlings, such as "T Mel 1.2", T is the batch code, 1.2 is January 2.

Coming out from the laboratory, Ji Heliang came to the planting shed to observe the growth of loose cauliflower. "Pinus cauliflower" is a standard to judge the growth of loose cauliflower, while the shape of cauliflower in the shape of mushroom means that the bud surface of loose cauliflower should be uniform, so judge its quality. Ji Heliang plucked away a cauliflower beside him. "the appearance of this cauliflower is very good, the surface of the cauliflower is very neat, meets the loose standard, and it tastes crisp and sweet." At this point, Ji Heliang smiled with satisfaction. (Wu Xiaoxiao and Liu Andong)

Rice breeding station

"Occupational Diseases" of Scientific Research personnel

This is the second time that the author has come to Jiamusi Rice breeding Station of Kenfeng seed Industry.

When it is the season of transplanting rice seedlings, walking on the long ridge of the pool, the experimental fields look like bright mirrors. Countless lovely green elves in the fields line up neatly, emitting the fragrance of the soil, dancing in the wind, dancing in a very different way.

The identities of these green elves are different, with a total of more than 30,000 from F1 to F8, which adopt the means of combining conventional breeding with multi-way breeding techniques to innovate and introduce cold tolerance, multi-resistance and wide adaptability resources. new rice varieties are developed on a large scale by making use of high identification intensity and selection pressure. After this selection, perhaps which variety will become a delicious staple food on the table in the near future. Whether these varieties can enter the market as soon as possible mainly depends on the breeders' long-term observation and identification of their phenotypes, and then the effective selection, combination, regulation and fine management of their genotypes.

"now breeding is different from the past. In addition to continuing to observe in the field all the time, scientific and technological personnel should also constantly understand the market demand, change the direction and objectives of breeding in a timely manner, keep learning, and make use of emerging technologies to assist in breeding. it is necessary to carry out effective detailed analysis of all aspects of work, strict supervision, and no carelessness, so as to improve the efficiency of breeding." Xu Xide, chief scientist of rice breeding in Kenfeng seed Industry, stood in the experimental field, busy guiding the transplanting of rice seedlings.

Xu Xide manages the Jiamusi rice breeding station, and there are 10 breeders in the park with a total area of 135 mu.

In the words of researchers, the breeding station is their home, eating here, living here, and taking good care of the home. Zong Shujuan is changing the soil for her potted plants: "these flowers will be transplanted to the previously planned and designed place in a few days." Interestingly, Zong Shujuan has neatly labeled each flower, which is like an "occupational disease" for breeders. Not only Zong Shujuan, this kind of "occupational disease" is reflected in almost every little thing that every breeder does. Although they deal with soil every day, the breeding stations are tidy and orderly, the equipment and machinery are discharged neatly, the dormitories of scientific and technological personnel are clean and comfortable, and the open spaces in the park are littered with fruit trees and all kinds of vegetables.
