Chapter 364 Breeding new varieties of tomatoes

The second step in the plant cross-breeding experiment is emasculation. Basically, self-pollinating or bisexual plants need to emasculate if they want to carry out cross-breeding.

The so-called emasculation is to remove the stamens before they crack and scatter pollen, which is mainly performed on the female parent.

Tomatoes are self-pollinating crops, and nature is no exception.

After emasculation, it is bagged, that is, the emasculated female flowers are covered with butter paper to protect them from accidental pollination or contamination by foreign pollen.

The fourth step is pollination.

Generally, on the second day after emasculation and bagging, the pollen is taken immediately when the male parent flower is open, and then the pollen is applied to the female parent with a small brush, which can ensure the highest seed setting rate after pollination.

The second step to the fourth step, collectively referred to as artificial emasculation and pollination, are the most important technical links in tomato hybrid breeding. Whether the operation is correct or not directly affects the quality and yield of seeds.

Qin Ke carefully peeled off the yellowed buds, removed the stamens, and then bagged them one by one. After completing this step, he adjusted the time to speed up, and immediately stopped the time when the male parent just bloomed to collect and pollinate.

This job is a test of patience and fine manipulation. Fortunately, he is a virtual body formed by mental power. The manipulation of his fingers can be perfectly controlled according to his consciousness, and he can perform various fine movements. girl to do the steps.

In this A-level knowledge "Cultivation Methods of Five Hybrid Grain Crops", in addition to various "pairing schemes" for hybrid breeding, such as A×B, (A×B)×(C×D) or even (A×C ) × (B × C), etc., the real most technical content is the special pollination tips, pollination tips, including time, speed, coating times, etc., as well as the combination of light intensity, as long as the operation is strictly followed, the seed The high-quality rate and result rate can be increased to a terrifying 95%.

And it also records how to carry out large-scale, low-cost breeding and production methods, as well as various standardized details of sowing and planting, such as temperature and humidity, PH value, what kind of fertilizer to apply, and how long to shine, so as to achieve the best planting effect .

Of course, these are not suitable for individuals, but for those large-scale planting enterprises, such technical details play a vital role in saving costs and increasing production.

And these are patentable.

Qin Ke feels that if his experiment is successful, these technologies will be registered as patented technologies, which can completely form another fist patented product of Lime Technology.

As for producing and growing it yourself?Qin Ke didn't think about it at all. He didn't have the time and energy, and he didn't have much interest in industrial production. What he was most interested in was experimental research, such as these fine experiments now.

He concentrated all his energy on carefully pollinating the various parents, and then made label records, and at the same time recorded the experimental data with pen and paper.

With more times, Qin Ke's operation will inevitably make mistakes, but overall the pass rate is still quite high.

Finally, all the steps were completed, and the parents produced tomatoes with different appearances.

Qin Ke completed the production of the first generation of seeds according to the method in his knowledge, and then soaked and sowed the seeds...

After seeing the increased speed of time, the first generation of "Type I", "Type II"... "Type VII" hybrid tomatoes sprouted, grew up, bloomed, and bear fruit. Full of sense of accomplishment and joy.

After recording the seven new varieties born from the theory in detail, Qin Ke verified the results one by one.

"Big success!" Qin Ke was very satisfied with the result, which can be called excellent.

For example, a tomato with very low soil fertility requirements can even grow and bear fruit in barren soil with a certain salinity, but the yield is slightly lower and the quality is slightly worse, but for those barren land and saline-alkali land that were originally abandoned , being able to plant such economic crops is already a major technological breakthrough turning waste into treasure. I don’t know how many farmers will cheer and even cry for it. This will also help to change the backwardness of many mountainous areas. !

Another example is the IV type of tomato. Originally, the branching ability of ordinary tomatoes is very strong, and side branches will continue to grow, which will affect the appearance and results. It needs repeated pruning and forking, but the IV type of tomato transforms the branching ability into upward climbing. Growth ability, especially suitable for planting on balconies with anti-theft nets. It is water-resistant, drought-resistant, sun-resistant, and cold-resistant. Red fruit will definitely become the favorite of urban white-collar workers, especially girls.

At that time, you can see tender green leaves and red fruits everywhere in the reinforced concrete of the city. What a wonderful scene!

Qin Ke fantasized about the scene of the seven new varieties of tomatoes in these virtual worlds, and his mood suddenly surged.

It's just that this result didn't come easily.

If in the real world, and there is no "Cultivation Method of Five Hybrid Grain Crops" as a guideline, to achieve similar experimental results, it would take as little as ten or eight years, and as much as 30 to [-] years.

And in this virtual world, he only spent less than an hour. How much trial and error cost and time and energy cost have been saved?
Taking a deep breath, Qin Ke forcibly suppressed the excitement in his heart, recorded all the experimental data and results in detail, and then firmly remembered all the experimental data in his mind before returning his consciousness to the real world.

Even though he has been busy for so long, the actual time has only passed half an hour.

Qin Ke stretched, sat up straight, pretending to have just woken up.

Along the way, Ning Qingyun did not sleep, but quietly wrote the story of "The Wonderful Mathematical Journey of Kitty Lemon and Puppy Keke" in a small notebook. Seeing this, she raised her head and said softly: "It will take a while You just arrived at school, do you want to sleep for a while?"

Qin Ke was in a happy mood, and said with a smile, "No need, is Jun'er free? Let's discuss the 'cross-breeding' plan?"

Although Qin Ke has successfully planted seven new varieties of tomatoes in the virtual scientific research and experiment center, it will take about four months at the fastest to reproduce and complete the seed production work in a greenhouse in the real world, and then plant them. It will take another three or four months to verify new varieties, and it will take at least the middle of next year to come up with the final scientific research results.

Of course, Qin Ke and Ning Qingyun couldn't do all these complicated experimental work. They would only participate in the most important links, such as emasculation, pollination, and seed production.The rest of the work was mainly handed over to the recruited researcher Wei Xueming and a few old farmers.

Qin Ke also plans to write a small program to let Xiaoguang remotely and automatically handle the temperature, humidity, and illuminance in the large greenhouse according to the function curve he formulated, so as to ensure that the experimental results in the virtual world can be restored to the maximum extent and ensure that the experiment can be done once. Successfully hatched technology patents.

In addition to the patent, the paper is also very important. After the patent is registered, Qin Ke plans to write a paper with Ning Qingyun and publish it in top domestic journals and even foreign "Nature" magazines to increase the popularity of the patent.

……

After bidding farewell to Zhou Shutao, Qin Ke and Ning Qingyun walked and chatted, and soon finalized the experimental plan of "tomato breeding and improvement".

Qin Ke didn't directly tell Ning Qingyun the most correct seed pairing plan, but proposed more than 30 different seed pairing plans in the form of "hypotheses". There are some correct ones and some wrong ones, but as long as they are tested at the same time, they will surely succeed Seven high-quality new varieties have been cultivated in a timely manner.

The disadvantage is that it takes more manpower and material resources, but the advantage is that scientific research results can be formed very naturally and credibly.

Ning Qingyun was very interested in this subject, and she took the initiative to write the experimental planning book and the theoretical part of the thesis with great interest.

Now she has completed the basic theoretical knowledge of the freshman biology department with Qin Ke. As long as she adds the knowledge of "crop breeding", the theoretical part of the thesis is basically formed, plus the details of cultivating seeds in the next year. The experimental data can be written into a paper.

The two of them are not in a hurry. They can apply for a patent in one year and publish a paper in two years, which is considered very fast.

The reason why the development speed of applied disciplines cannot keep up with theoretical disciplines is that theoretical disciplines only need to use their pens and brains to come up with logical hypotheses based on mathematical thinking or observed phenomena, while applied disciplines need to spend countless hours Concentrate on doing experiments and testing theories...

In any case, Qin Ke and Qin Ke are very excited to start their own scientific research experiment project, especially Ning Qingyun, who is very interested in scientific research, and now she can start to study and practice with Qin Ke again, which is even more exciting Jumping for joy, there was always a smile on his usually cool little face, causing the boys on the university campus to peek at him frequently.

"After the tomato hybrid breeding is done, I plan to form a scientific research team to tackle other experimental research on rice, corn, wheat, and rapeseed. We only provide the main ideas and experimental plans. The specific work will be completed by the scientific research team. What do you think? Just like when we were doing the operating system project. I don’t want you to spend all day in the greenhouse serving those crops.”

As Qin Ke said, he pinched the girl's soft and smooth little hand. Although the scientific research experiment was very interesting, he felt a little reckless when he thought that such a beautiful and exquisite little hand, like a work of art, would be used to cultivate plants in the field.

Ning Qingyun pursed her lips and chuckled: "I think it's quite interesting, but I listen to you."

What Qin Ke said about establishing a scientific research team is sincere. Of course, this at least has to wait until the tomato hybrid breeding has achieved results and Lime Technology's popularity in plant hybrid cultivation has been established before proceeding.

The two went back to check the time. Because they left early, they left around seven o'clock. Even if they went out for a while, it was only around eleven o'clock now. I don't know if the class meeting is over.

Qin Ke called the counselor Lu Chunyuan, and Lu Chunyuan said mysteriously: "The class meeting is almost over, but it's just right for you to come here now, in Room 201 of Teaching Building A. Come here quickly, the students are waiting for you."
