my scientific age

Chapter 190 The yield per mu is 250 kilograms!

The wheat stalk is strong and tall, with a height of about 80 cm, the wheat ears are rectangular, and the wheat kernels are red and plump, with about 50 grains.

Looking at this golden-yellow wheat that exudes extreme temptation, Yu Hua's eyes are full of surprises. If nothing else, this is a natural hybrid wheat, and it is an ideal parent for hybridization experiments. It can be used as both the female parent and the male parent. .

Gene mutations often occur. In nature, there are a certain number of natural hybridization events. The male and female parents of later generations of super wheat and indica super hybrid rice are all derived from natural hybridization.

Yu Hua took a step forward and carefully uprooted the hybrid wheat plant. His movements were subtle and gentle, and he did not dare to be careless, and quickly uprooted the wheat.

"I hope you are a gift from God." Yu Hua held this precious wheat plant with his hands in front and back, full of anticipation, and turned back.

The most critical and difficult part of hybrid breeding is to find natural hybrid parents. The parents are divided into female and male parents, and the number is not fixed. Two or more varieties can be hybridized.

With the parent of the variety, the dungeon of [Solving China's Food Crisis] can be opened.

However, natural hybrid parents are by no means easy to find. Most people spend their entire lives and cannot find a real natural hybrid parent. Yuan Lao, who is known as the Great Druid, was lucky to find one. The natural parent of the indica-type super hybrid rice will eventually solve the food crisis in China permanently.

The natural hybrid parent is also known as a 'treasure bestowed by God'.

Could this wheat that I accidentally saw be a real natural hybrid wheat?

uncertain.

But Yu Hua hopes it is.

At this time, Liu Wei and Lin Wan had already got off the car and stood on the side of the road, staring at the wheat Yu Hua held in both hands, with anticipation in their eyes.

"How is it?" Lin Wan immediately asked when Yu Hua returned to the road.

"This wheat plant has an 80% probability of being a natural hybrid wheat. You can see that its ear shape, straw diameter and height are better than other wheat in the field. I counted the number of grains, and it reached 50 per ear. It is very special, and the weight of 25 grains may reach [-] grams." He raised the whole wheat plant with both hands and placed it in front of the two of them.

"Thousand-grain weight? Is this indicator important?" Lin Wan had some doubts about the term Yu Hua proposed. She was basically blank when it came to botany and genetics.

"Very important, 20-grain weight is an important data to measure the yield of wheat. Through the weight of 50 grains, we can clearly see the difference of wheat varieties, and calculate the yield data of wheat. Assuming this special wheat in my hand, the average cost per mu of land is The ear volume is 25 ears, the single ear of wheat is 20 grains, and the weight of one thousand grains is 50 grams, which is 1000 * 1 = 1 million grains. , divided by 25 grams and the yield per mu is 25 kilograms." Yu Hua nodded and replied.

The yield per mu is 250 kg?

Lin Wan and Liu Wei were stunned for a moment.

At the last moment, I was still studying the goal of achieving a yield of 300 kg per mu, but now I have directly found a natural hybrid wheat variety with a yield of 250 kg per mu?
God, is this really no joke?
"Student Yu, if it belongs to natural hybrid wheat as you said, does that mean that we will soon be able to cultivate high-yield wheat?" Liu Wei swallowed his saliva. The target, looked at this wheat plant with heavy ears, resisted the excitement in his heart, kept the appearance of a housekeeper, and asked.

"Yes, it can be used as the parent of a hybrid test variety. The basic principle of the hybrid test method is to select high-quality wheat from different regions for hybridization, and continue to cultivate it from generation to generation. Finally, two or more hybrid test varieties are cultivated, and then cross-breed with each other to cultivate the final variety. "

Yu Hua nodded towards Liu Wei, glanced at the wheat in his hand, turned to Lin Wan, and said, "The advantage of natural hybrid wheat is that you can abandon the early stage of cultivating hybrid test varieties and go directly to cultivating the final hybrid. In terms of varieties, this is a very ideal test variety. The number of grains per ear reaches 50, and the thousand-grain weight is about 25 grams. The yield is very impressive. We just need to find another natural hybrid wheat from other regions and carry out hybrid cultivation with it. , within three years, the first generation of high-yield wheat with a stable yield of more than 250 kilograms per mu can be obtained."

The preciousness of natural hybrid individuals lies in this. Nature has completed the most difficult pre-hybrid work. What a scientific researcher needs to do is to directly cultivate the final product.

If this unexpectedly discovered wheat is indeed a natural hybrid wheat, then it will not be a dream to develop a high-yield wheat with a stable yield of more than 250 kilograms per mu in three years.

Stablize!

This is a key requirement of modern breeding. Only when the yield per mu is extremely stable and the technology to offset the deterioration of the variety can be mastered, can the cultivation of high-yield wheat be completed.

Of course, the premise is that the wheat must be a natural hybrid. If it is not a natural hybrid, then these are all empty talk.

This easy-to-understand and not difficult explanation of the theory of hybridization ended. Everyone present, including the driver, understood the meaning and importance of natural hybrid individuals. Liu Wei looked at the mutant wheat in Yu Hua's hand, as if he was looking at it. She looks like a peerless beauty.

"Yu Hua, how to verify whether it is a natural hybrid wheat?" Lin Wan continued to ask.

"Planting experiments, referred to as farming."

Yu Hua replied with a smile: "Let's get in the car first, Steward Liu, please keep this wheat plant, if possible, please find the owner of this land, if the other party is a poor peasant, give him a piece of ocean, if it is a landlord, let it go."

When the words fell, he handed the mutant wheat in his hand to Liu Wei.

"Okay, classmate Yu." Liu Wei took the mutant wheat carefully, as if he were dealing with a peerless treasure, daring not to be careless.

The group got into the car again, and the Buick started driving again, heading for the experimental site in Zhaobeikou, Baiyangdian. However, after an accident on the way, everyone's mood changed again.

Liu Wei's attention was all on the mutants. I have to say that there were too many surprises for him during this time. First, there was Mr. Zhang San who helped him, and second, there was Yu Hua, a talented student who proposed the Seven Pagodas of the Yu Family. , red secret deciphering materials, three gunpowder technologies, the Yu's Seven Pagodas under development, including the newly discovered mutant wheat variety, all of which are of little help to the organization.

Is this the legend of the bitter end?

After suffering countless hardships, trekking mountains and rivers, tumbling over snow-capped mountains, crossing grasslands, and the [-]-mile Long March, the organization once fell into the darkest moment. Now, I finally see hope.

At this moment, Liu Wei's mood is extremely complicated, excited, looking forward, and sad. He is playing the role of a housekeeper. Because he does not want to arouse Yu Hua's disgust by revealing his true identity for the time being, he is holding back his inner emotions.

"Yu Hua, I want to learn botany and wheat hybridization technology with you." Lin Wan, who had been taking notes after getting in the car, finally put down her pencil. The notebook was full of what Yu Hua had just described. She looked at Yu Hua and sipped. His lips, as if determined, spoke earnestly.
