The second step in plant hybrid breeding experiments is to remove males. Basically, if self-pollination or bisexual reproduction plants want to undergo hybrid breeding, they need to remove males.

The required male removal will be removed before the stamens crack and pollen scatters. This is mainly carried out on female parents.

Tomatoes are self-pollinated crops, so they are no exception.

After the male is removed, it is a bag, that is, the female flowers that are removed are covered with butter paper to protect them to avoid accidental pollination or contamination by foreign pollen.

The fourth step is pollination.

Generally, the day after removing the male bag, the mother's flower will be taken immediately when it blooms, and then the pollen is applied to the mother's body with a small brush, which can ensure the highest fruiting rate after pollination.

The second to fourth steps, collectively known as artificial de-pollination and pollination, is the most important technical link in tomato hybrid breeding. Whether the operation is correct directly affects the quality and yield of the seeds.

Qin Ke carefully picked the yellowed buds and peeled them, removed the stamens, and then set them up one by one. After completing this step, he adjusted the time and immediately paused the time when his father had just bloomed to collect and pollinate.

This work tests patience and fine operation very much. Fortunately, he is a virtual body formed by mental power. The operation of his fingers can be perfectly controlled according to consciousness and performs various fine movements. Otherwise, he may only let a careful and skillful girl like Ning Qingyun do these steps.

In this A-level knowledge, "The Cultivation Methods of Five Hybrid Grain Crops", in addition to various hybrid breeding "pairing plans", such as AxB, (AxB)x(C)xD) and even (AxC)x(B)xC), the most technical content is the special powder picking tips, including time, speed, number of coatings, etc., and the light illumination coordination. As long as the operation is strictly followed, the quality rate and yield rate of the seed can be increased to a terrifying 95%.

It also records how to carry out large-scale and low-cost breeding methods, as well as various standardized details of sowing and planting, such as temperature and humidity, pH, what kind of fertilizer to apply, and how long to shine, so that the best planting effect can be achieved.

Of course, these are not suitable for individuals, but for large planting companies, such technical details play a crucial role in saving costs and increasing yields.

And these are patentable.

Qin Ke felt that if his experiment was successful, and these technologies were registered as patented technologies, it would completely form another patented product of Qingning Technology.

As for production and planting by himself, Qin Ke never thought that he did not have such time and energy, and he was not interested in industrial production. What he was most interested in is experimental research, such as these fine experiments now.

He concentrated all his energy, pollinated various parents carefully, then made label records, and recorded experimental data with paper and pen.

Once the number of times is too high, Qin Ke will inevitably make mistakes in his operations, but overall the pass rate is quite high.

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

Qin Ke followed the method of knowledge to complete the production of the first generation of seeds, then soaked and sowed...

Seeing the increased passage of time, the first generation of "i type", "ii type"... "vii type" hybrid tomatoes sprout, grow, bloom, and bear fruit. He wiped the sweat from his forehead, feeling full of accomplishment and joy.

The seven new varieties born from the theory were recorded in detail, and Qin Ke verified the results one by one.

"Great success!" The result was greatly satisfied with Qin Ke, and he could be called excellent.

For example, tomatoes with very low requirements for land fertility can even grow and bear fruit in barren and with a certain saline alkaline soil, but the yield is slightly lower and the quality is slightly worse. However, for those barren and saline-alkali land that were originally abandoned, having such cash crops to grow is a major technological breakthrough to turn waste into treasure. I don’t know how many farmers will be excited and cheer or even cry. This will also have a certain helping effect on changing the backward appearance of many mountainous areas!

For example, IV-growing tomatoes, the branching ability of ordinary tomatoes is strong, and they will continue to grow side branches, affecting their beauty and results. They need to be pruned and crossed repeatedly. However, IV-growing tomatoes transforms branching ability into upward climbing and growth ability, which is especially suitable for planting on balcony with anti-theft nets. It is water-resistant, drought-resistant, sun-resistant, and cold-resistant, and is very easy to feed. As long as you water regularly and add a few drops of nutrient solution, you can continue to grow and produce beautiful and delicious little red fruits. It will definitely become the favorite of urban white-collar workers, especially girls.

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

Qin Ke was fantasizing about the scene after the seven new varieties of tomatoes in these virtual worlds were released, and he was immediately excited.

But this result was too difficult.

If in the real world, there is no guidance on "The Cultivation Methods of Five Hybrid Grain Crops", if you want to achieve similar experimental results, it will take ten or eight years less, and at most twenty or thirty years less.

And in this virtual world, it only took less than an hour, which saved how much trial and error costs and time and energy costs?

Taking a deep breath, Qin Ke forced himself to suppress the excitement in his heart, recorded all the experimental data and experimental results in detail, and then 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 reality has only been 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 second year of high school in the small notebook, "The Wonderful Mathematics Journey of the Kitten Lemon and the Puppy Keke". Seeing this, she looked up and said warmly: "It will take a while before you get to school. Do you want to sleep for a while?"

Qin Ke was in a happy mood and smiled and said, "No need, is Yun'er free? Let's discuss the plan for 'hybrid breeding'?"

Although Qin Ke has successfully tried to plant seven new varieties of tomatoes in the virtual scientific research experimental center, it will take about four months to reproduce and complete seed production in a real-world greenhouse. Then it will take another three or four months to plant and verify the new varieties. The final scientific research results will be drawn at least until the middle of next year.

Of course, it is impossible for Qin Ke and Ning Qingyun to do all these complex experimental work. They will only participate in the most important links, such as going to the hero and pollination, and seed production. The rest of the work is mainly handed over to the recruited researcher Wei Xueming and several old farmers.

Qin Ke also plans to write a mini program to let Wei Guang automatically handle the temperature, humidity, light and other work in the large greenhouse according to the function curve he has formulated, so as to ensure that the experimental results in the virtual world can be restored to the maximum extent, and to ensure that they can succeed in one go and technical patents can be incubated.

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

...

After saying goodbye to Zhou Shutao, Qin Ke and Ning Qingyun chatted while walking, and soon finalized the implementation of the experimental plan for "Tomato Breeding Improvement" first.

Qin Ke did not directly tell Ning Qingyun the most correct seed pairing plan. He only proposed more than 30 different pairing plans in the form of "hypothesis", including correct and error. However, as long as the experiment is conducted at the same time, seven high-quality new varieties will surely be successfully cultivated.

The disadvantage is to spend more manpower and material resources, and the advantage is to be able to form scientific research results very naturally and credibly.

Ning Qingyun was very interested in this topic. She took the initiative to take charge of the preparation of experimental planning and theoretical work of the paper.

Now she has learned the basic theoretical knowledge of the first year of biology with Qin Ke. As long as she adds the knowledge of "crop breeding", the theoretical part of the paper will basically take shape. Adding the detailed experimental data on seed cultivation in the next year, she can write a paper.

The two of them are not in a hurry to apply for a patent in one year and publish a paper in two years. This is considered very fast.

The reason why applied disciplines cannot keep up with the theoretical discipline is that the theoretical discipline only needs to write and brain, and propose logical assumptions based on mathematical thinking or observed phenomena, while applied disciplines require countless time and energy to do experiments and verify the theory...

No matter what, Qin Ke and the other two were still very excited to actually start their own scientific research and experimental projects, especially Ning Qingyun. She was very interested in scientific research, and now she was able to start research and practice with Qin Ke. She was even more excited. Her smile had always been on her cold little face, which made the boys on the university campus frequently peek.

"After working on the experimental research on other rice, corn, wheat and rapeseed, I plan to form a scientific research team to solve the problem. We only provide the main ideas and experimental planning books, and the specific work will be completed by the scientific research team. What do you think? Just like when we were working on the operating system topic, I don't want you to stay in the greenhouse all day to serve those crops."

Qin Ke said as he pinched the girl's tender and smooth little hands. Although the scientific research experiments were very interesting, he felt that it was a waste of resources when he thought that such a beautiful and exquisite little hand as a work of art was going to cultivate plants in the field.

Ning Qingyun chuckled: "I think it's quite interesting, but I just listen to you."

Qin Ke said that it is sincere to establish a scientific research team. Of course, at least it will take time for the tomato hybrid breeding to achieve results and the popularity of Qinglien Technology in plant hybridization, and then move forward.

The two of them returned to check the time. They left early and left around seven o'clock, even if they went out for a while, it was only around eleven o'clock now. I wonder if the class meeting was over.

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