My short video leads to ancient times, and the ancients break the defense!

"Bastard?".

Song Yingsheng was a little confused, "Hybrids are the answer?"

Song Yingxing didn't answer, just looked at the air, and after a long time, he said

"The world is in crisis, the building will collapse, even if we get the grain, we can't save the Ming Dynasty. "

"We don't need food, we need fire. "

When Song Yingsheng heard this, his face instantly sank.

The emperor star is shaking, the mountains and rivers are broken, and the scene of the dead country is close at hand.

...

[After Yuan Lao thought about the answer, he rushed home. 】

[He divided the 1024 rice stalks he harvested into two piles according to their height, and then carefully counted the number of the two piles of rice stalks, all of which were counted clearly. 】

[It turned out that the number of tall poles was 768, the number of short poles was 256, and the number ratio was 3:1

[Old Yuan was ecstatic, he shouted, Mendel old man, there is yours, there is really yours!!].

[That's right, this is Mendel's law of gene segregation, which shows that this rice is a hybrid, a hybrid rice.] 】

[It stands to reason that all rice should be purebred rice, but this rice is a hybrid rice, but it stands out from the crowd, which shows that hybrid rice has more advantages than purebred rice. 】

[Yuan Lao got this conclusion, if he got the treasure, he understood that only hybrid rice can the future of Chinese rice. 】

[After discovering the secret of hybrid rice, Yuan Lao knew that his knowledge of rice was shallow, and immediately went to the Agricultural College to ask his mentor. 】

[However, due to some special reasons, Yuan Lao did not see his teacher, so he could only go to the Beijing Academy of Agricultural Sciences to ask Mr. Bao for advice. 】

[In Beijing, Mr. Yuan had a deep conversation with Mr. Bao, and he told Mr. Bao about his discovery, but Mr. Bao told him that hybrid rice has more advantages, which is common sense. 】

[Yuan Lao was deeply shocked, the secret he regarded as a treasure had already been discovered. 】

[However, he was not discouraged, he told Mr. Bao his idea. 】

[He told Mr. Bao that since there is natural hybrid rice, there must be natural male sterile strains, as long as the male sterile strains can be artificially cultivated to produce artificial male sterile strains on a large scale. 】

[In this way, the cultivated rice will be hybrid rice, which can expand the yield of Chinese rice.] 】

[However, Mr. Bao's words hit Yuan Lao again. 】

[Teacher Bao told Yuan Lao that this technology had been manufactured by scholars in the Wa Kingdom four years ago, but it was blocked and kept secret, and the Wa Guo was unwilling to share it. 】

[He told Yuan Lao earnestly: Let's go, go back, hybrid rice is not something that anyone can do. 】

[I thought that Yuan Lao would be discouraged, but he said that if others can do it, we can also do it in Huaxia. 】

[Teacher Bao saw that he was quite strong-willed, so he took him to the library of the Academy of Agricultural Sciences, so that Yuan Lao could consult the books by himself inside. 】

[The library has the most advanced agricultural technology in the world, and Yuan Lao is hungry to absorb knowledge here, often reading books until late at night. 】

[Before leaving, Mr. Bao solemnly warned Yuan Lao: It takes eight years to study a rice variety, you should think carefully, think about how many eight years you have. 】

[Yuan Lao still said that he wanted to make hybrid rice no matter what, and when Mr. Bao saw this, he told him a way to save time. 】

[Once you find a natural male sterile strain, you will run with the sun as soon as possible, that is, breeding in the south and breeding in the north. 】

[Breeding in Hainan in winter, because it is a natural greenhouse, go to Guangxi in autumn, and return to Hunan in summer, so that it only takes three years to complete the test of a variety of rice, which will make your scientific research life two to three times longer than others. 】

[Of course, the premise is that you first find a male sterile strain.] 】

[After listening to this, Old Yuan bowed deeply to Teacher Bao. 】

[Teacher Bao saw the perseverance in Yuan Lao's eyes, and finally said: Let's go, don't look back if you recognize it, and come to me again if you have difficulties. 】

[Yuan Lao returned to Nongjiang Agricultural School again and began to work hard to find natural male sterile strains. 】

[Natural male sterile strains are the kind of rice that does not crack and does not produce seeds. 】

[After the teachers of the agricultural school found out, they all felt that Yuan Lao was crazy, and they must know that the probability of the appearance of natural male sterile strains is only 1 in 50,000. 】

[But Yuan Lao did not hesitate, he took a magnifying glass, barefoot, and checked 120,000 rice plants in a year, but found nothing, but fell into a skin disease. 】

[The window period for finding natural male sterile plants is only a few days when heading and flowering, and the time is very urgent. 】

[Yuan Lao forgot to sleep and eat, did not dare to delay for a moment, and ran in the field every day, just to find the most critical male sterile plant. 】

[Finally, under Yuan Lao's unremitting search, he finally found the natural male sterile strain. 】

[At that moment, he shouted excitedly: Found it! It appeared! Hold the pulp to the bottom!!].

[It was July 5, 1964, at 2:25 p.m.] 】

[This year, Yuan Lao found the first natural male sterile plant, and the second year found five more, Yuan Lao carefully cultivated these seedlings, and finally obtained one hundred and nine experimental seedlings. 】

[This is the second miraculous discovery in the life of the old man Yuan, and the next step is to consider the problem of cultivating hybrid rice seeds. 】

[For the rice varieties of hybrid rice, the whole world is stuck in the two-line method, because the hybrid rice is in the second generation, and the widow rice will revert to the hermaphroditic husband and wife rice again. 】

[Therefore, the whole world believes that hybrid rice cannot be mass-produced at all.] 】

[However, Yuan Lao pioneered the invention of three-line hybrid rice, which is the basis for the success of hybrid rice, and it is precisely because of three-line hybrid rice that high-yield rice in China has become a reality. 】
