The wheat stalks are strong and tall, with a height of about 80 cm by visual inspection. The wheat ears are rectangular and the wheat grains are red and plump. The number is about 50 grains. It is in sharp contrast with the low and thin wheat around it, revealing its excellent characteristics.
Yu Hua's eyes were full of surprises as he looked at this golden wheat that exuded ultimate temptation. If nothing unexpected happened, this was a natural hybrid wheat and an ideal parent for hybrid experiments. It could be used as either a female parent or a male parent.
.
Gene mutations often occur. In nature, there are a certain number of natural hybridization events. The male and female parents of future super wheat and indica super hybrid rice are all derived from natural hybridization.
Yu Hua stepped forward and carefully uprooted the hybrid wheat. His movements were subtle and gentle, not daring to be careless, and he quickly uprooted the wheat.
"I hope you are a gift from God." Yu Hua held the wheat that he regarded as a treasure with his hands in front of him, and turned back with his heart full of expectation.
The most critical and difficult part of cross-breeding is to find natural hybrid parents. Parents are divided into female parents and male parents. The number is not fixed. Two or more varieties can be crossed.
Only with the breed parents can you open the copy of [Solving China's Food Crisis].
However, natural hybrid parents are by no means so easy to find. Most people spend their entire lives unable to find a true natural hybrid parent. However, Mr. Yuan, known as the Great Druid, was lucky enough to find one.
This natural parent of indica super hybrid rice will finally single-handedly and permanently solve China's food crisis.
The natural hybrid parent is also known as the ‘treasure given by God’.
Could this piece of wheat 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 gotten out of the car and stood on the roadside, staring closely at the wheat held by Yu Hua in both hands, with some anticipation in their eyes.
"How was it?" Lin Wan asked immediately after Yu Hua returned to the road.
"There is an 80% possibility that this wheat is a natural hybrid wheat. Look at its ear shape, stalk diameter and height. It is better than other wheat in the field. I counted the number of wheat grains, and it is about 50 grains per ear.
There are many, and the characteristics are very special. The weight of a thousand grains may reach 25 grams." He raised the whole wheat plant with both hands and placed it in front of the two people. Yu Hua, with a serious face, introduced the two people in an orderly manner.
"Thousand-grain weight? Is this indicator important?" Lin Wan was a little confused about the terms Yu Hua proposed. She was basically blank about botany and genetics.
"It's very important. The thousand-kernel weight is an important data to measure wheat yield. Through the thousand-kernel weight, we can clearly see the difference in wheat varieties and calculate the wheat yield data. Using the special wheat in my hand as an assumption, the average cost per acre of land is
The number of ears is 200,000 ears, 50 wheat grains per ear, and the weight of 1,000 grains is 25 grams, which is 200,000 * 50 = 10 million grains. The total number of grains divided by 1,000 grains equals 10,000, and 10,000 × 25 grams equals 250,000 grams.
, divided by 1000 grams, the yield per mu is 250 kilograms." Yu Hua nodded and replied.
The yield per mu is 250 kilograms?
Lin Wan and Liu Wei were stunned for a moment.
Just a moment ago, we were still studying the goal of achieving a yield of 300 kilograms per mu, but now we have directly found a natural hybrid wheat variety with a yield of 250 kilograms per mu?
God, is this really not a joke?

"Classmate Yu, if it is a natural hybrid wheat as you said, does it mean that we will be able to breed high-yielding wheat soon?" Liu Wei swallowed his saliva. He no longer cared about going to Baiyangdian Zhaobeikou Experimental Site today.
Target, looking at the heavy wheat with his eyes, he suppressed the excitement in his heart and asked as a housekeeper should.
"Yes, it can be used as a parent of hybrid test varieties. The basic principle of the hybrid test method is to select excellent wheat from different regions for crossbreeding, and continue to breed it from generation to generation. Eventually, more than two hybrid test varieties will be cultivated, and then cross each other to develop the final variety.
"
Yu Hua nodded towards Liu Wei, glanced at the wheat in his hand, then looked at 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.
As for varieties, this is a very ideal experimental variety, with a single panicle of 50 grains and a thousand-grain weight of about 25 grams. The yield is very impressive. We only need to find another natural hybrid wheat from other regions and conduct cross-breeding with it.
, within three years, we will be able to obtain the first generation of high-yield wheat with a stable yield of more than 250 kilograms per mu."
This is the preciousness of natural hybrid individuals. Nature has already completed the most difficult preliminary hybridization work. What researchers have to do is to directly cultivate the final product.
If this accidentally discovered wheat is indeed a natural hybrid wheat, then it will not be a dream to develop high-yielding wheat with a stable yield of more than 250 kilograms per mu in three years.
Stablize!
This is a key requirement for modern breeding. Only when the yield per mu is extremely stable and the technology to offset the degradation of varieties 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.
After this easy-to-understand and not difficult explanation of hybrid theory knowledge, everyone present, including the driver, all understood the significance and importance of natural hybrid individuals. Liu Wei looked at the mutant wheat in Yu Hua's hand, as if
She looks like a peerless beauty.
"Yu Hua, how do you verify whether it is natural hybrid wheat?" Lin Wan continued to ask.
"Planting test, referred to as planting."
Yu Hua smiled and replied: "Let's get in the car first. Butler Liu, please take good care of this wheat plant. If possible, please find the owner of this land. If the other person is a poor farmer, give him a piece of ocean. If he is a landlord,
forget about it."
After finishing speaking, he handed the mutated wheat plant in his hand to Liu Wei.
"Okay, classmate Yu." Liu Wei carefully took the mutated wheat, as if he were treating a peerless treasure, not daring to be careless in the slightest.
The group of people got in the car again, and the Buick started driving again, heading towards the experimental site at Zhaobeikou, Baiyangdian. However, after an unexpected surprise on the way, everyone's mood became different again.
Liu Wei focused all his attention on the mutant strain. It has to be said that there were too many surprises for him during this period. Firstly, there was Mr. Zhang San who helped, and secondly, there was the genius student Yu Hua who proposed the Seven Pagodas of the Yu Family.
, red secret deciphering information, three types of gunpowder technology, Yu's Seven Pagodas under development, including the newly discovered mutant wheat varieties, all of which are of little help to the organization.
Is this the legendary happiness that comes after all hardships?
After enduring countless hardships, trekking through mountains and rivers, climbing over snow-capped mountains, crossing grasslands, and the 25,000-mile Long March, the organization was once plunged into the darkest moment. Now, we finally see hope.
At this moment, Liu Wei's mood was extremely complicated, including excitement, expectation, and sadness. He, who was playing the role of butler, suppressed his inner emotions because he did not want to arouse Yu Hua's disgust by revealing his true identity for the time being.
"Yu Hua, I want to learn botany and wheat hybridization technology from you." Lin Wan, who had been taking notes since getting in the car, finally put down her pencil. The notebook was full of what Yu Hua had just said. She looked at Yu Hua and took a sip.
His lips, as if he had made up his mind, said seriously.
