Chapter 990: Sterile strains, a head start on hybrid rice research
At three o'clock in the morning, Quan Yi, who had finished his morning workout and breakfast, appeared on Jin Shu's back.
With his bare feet rooted in the sticky soil, he waved his hand to direct Jinshu to divide the planting areas.
"The planting area is divided into four areas: east, west, north and south.
The east side, the most convenient location for people to transport, is designated as the medicinal planting area for three kinds of elixirs.
The west side that is farthest and closest to Taiyiguan can be divided into an area for planting fairy grass.
The north side can be used for experimental rice hybridization and other food-related research planting.
The south side is reserved first in case the subsequent planting area is insufficient. ”
After making the divisions, Quan Yi first came to the westernmost piece of soil, and personally bent down and planted the fairy grass seeds he got from Dugu Bo one by one.
When a fairy seed is planted in a spring, the clear sound of germination will be heard in the wet soil.
After a while, along with the rich vitality, vibrant sprouts will grow on the surface of the black wet soil.
The hundred-fold acceleration and huge energy of this land directly promotes the germination of seeds.
There is no need for Quan Yi to take care of it carefully. These fairy seeds stretch themselves freely and take root in this perfect soil.
When Quan Yi planted all the seeds safely according to the habits of each fairy grass, many colorful star points appeared on the bare wet soil.
The longer the immortal seed is, the more its value will increase exponentially.
The jelly grass in Dugu Bo's place is at least ten thousand years old, so if Quan Yi cultivates 100,000 year old jelly grass, its effect will definitely reach a higher level.
However, even next to the Yin-Yang Golden Pond, it would take thousands of years to cultivate 100,000-year-old fairy grass.
Therefore, this area on the west side cannot be used in a short period of time.
In order to make the most of this area, Quan Yi, in addition to visiting Dugu Bo, is also using all the power at his disposal to collect various rare seeds and prepare to fill this area.
Even if you can't find the top fairy herbs, common fairy herbs like ginseng, fleece-flower root, Ganoderma lucidum, etc. can still enter the west area.
Not only Izumi is working hard on this part of the matter, but the power of the islands distributed on the mainland is also playing a role.
Planting the entire west side area is just around the corner.
After dealing with the immortal seeds, Quan Yi flew to the north side.
Viewed from a height, unlike the other three dark areas, the entire area on the north side is filled with green rice.
Under the breeze, the fragrance of green grass comes to your nose.
Viewed from a height, each rice plant is arranged neatly, like chess pieces placed neatly on a chessboard, densely packed but uniform.
Countless amounts of rice formed a blue ocean. Quan Yi's pupils shrank, and purple-gold light replaced the original color.
With the help of the Purple Gold Dragon Eye, Quan Yi constantly searches for special rice among the vast amounts of rice.
After a while, through meticulous observation, he quickly discovered several special rice plants.
You should know that rice is self-pollinating, which means that each flower has stamens and pistils.
During self-pollination, it will drop pollen from the stamens onto the pistils to create seeds.
But among so many rice plants, this is not the case for several plants. Their male organs cannot form normal pollen, react with their own healthy pistils, and reproduce normally.
If you have learned the basic principles of hybrid rice, you all know that there is a very important factor in it, which is to find the cytoplasmic male sterile line of rice. This kind of rice can completely accept pollen from rice with superior genes and breed hybrid rice.
Because there is no need to spend a lot of manpower and material resources for manual emasculation, the cost of breeding and seed production will be significantly reduced, and the efficiency will be greatly improved.
Of course, if large-scale breeding is to be carried out, it will be difficult to expand the scale with just a few sporadic sterile strains.
Therefore, at this time, a rice cytoplasmic vicious maintainer line that can maintain this sterility is needed.
This special individual has the ability to maintain the sterility of sterile plants, but miraculously, it can reproduce itself through self-pollination.
By combining these two species, a sterile line serving as a parent can be propagated in large numbers.
After completing this step, we will finally look for a method that can restore the fertile ability of the hybrid seeds and have hybrid vigor.
This is the three-line method of breeding hybrid rice.
Before the development of the island, Quan Yi taught the relevant theories to the agricultural department and asked them to conduct relevant experiments.
However, it is still somewhat unrealistic to find these three types of rice at the same time in just a few years.
However, now with this accelerated planting area, one day is equivalent to more than a hundred days.
Check out the 16-9 book bar and see the correct version!
The growth cycle of rice is more than a hundred days, which means that a complete growth cycle can be experienced in one day, and a one-year experiment can be completed in one day or three days.
Izumi is now experiencing firsthand how much help this terrifying speed can provide for hybrid rice research.
After finding the sterile plants, Quan Yi searched for external male pollen for artificial pollination and waited for the results.
Taking advantage of this time, he flew to the east side and planted all the medicinal materials needed for refining the elixir neatly above.
There are relatively many seeds of these medicinal materials, and with the wide variety, they occupied a quarter of the area for the first planting.
Based on the amount of the main materials grown here, when mature, at least 50,000 elixirs can be refined.
Wait until the seeds are mature and expand the seeds. It won't take long for the entire area to be planted, providing elixirs for 200,000 people.
You must know that the elixir is a one-time use. After each person takes it once, he can then use the Xuantian Kung on his own.
The current population is 400,000. Even if the birth rate is high, it will not be able to consume the 200,000 pills produced every year.
Although Quanyi had already overestimated the role of wet soil, when his expectations turned into reality, he still underestimated the horror of this holy land for planting.
"How do I feel that before the relevant infrastructure is laid here, I can advance the research progress by decades.
In other words, the entire process has been accelerated by more than a hundred times. Even if there are staff arriving, can anyone keep up with such a pace? ”
Quan Yi rubbed his eyebrows and found that if the efficiency was too high, there would also be problems with others not being able to keep up with this efficiency.
"It seems that we still have to let Jinshu assist with physical matters such as planting and harvesting. The researchers only need to focus on research."
After deciding on the future research method, Quanyi still has one very important thing to complete.
After several days of brewing, the entire barrier has reached a stage of steady improvement. During this period, the range that was deliberately suppressed by Quanchi has expanded and can now be unsealed.
Quan Yi stood on top of the transparent light mask above the Yin Yang Golden Pond, looked at the entire island in the east, and said softly:
"Let the entire island evolve together.
Yin Yang and Five Elements Flame Formation, expand! ”
Under Quan Yi's order, the silent barrier rapidly expanded outwards, shrouding the entire island inside.
