"The rhizome is stout, the plant is strong, the pods are dense, the top pods are abundant, the plant type is astringent, and handsome!"

"It is a medium-grain variety, with a large number of pods per plant, a large number of grains per plant, and a grain weight of more than 20 grams, which is cool!"

"Perfect performance. ”

"I just don't know how resistant it is. ”

Before the harvest began, agricultural experts from the World Farmers' Organization delegation gathered at the edge of the soybean field and looked at what could be a cross-generational variety of Jiagu soybeans.

Whether or not they are happy to see "Jiadou No. 13" bred by the Chinese, for experts who have devoted their lives to soybean breeding, it is always pleasing to see a more perfect variety.

Whether a crop is suitable for promotion or not can be seen at a glance in many cases.

Soybeans, for example.

The first thing they see is the height of the pods.

Some soybean varieties begin to set pods from 3~5cm in root, and there are many branches, and the yield is indeed not low, but it is not suitable for large-scale promotion.

As the saying goes, "A handful of grass for wheat and a handful of bran for grain", and the same goes for soybeans. If the height of the bottom pod of the soybean plant is not enough, it is easy to lodging, not to mention, the difficulty of mechanical harvesting increases, and the harvesting cost increases a lot, and it is not even suitable for mechanized harvesting at all.

Such varieties may have value in intensively cultivated countries like China, while in the Americas, few farmers would consider planting.

And like the variety "Jiadou No. 13", the height of the bottom pod is more than 15cm, and the plant height is more than 50cm, which is definitely a tall "handsome guy", and mechanized harvesting is no problem.

The grain weight per plant of "Jiadou 13" has made a group of international soybean breeders show a rippling smile.

Many farmers prefer to choose large-grain varieties when buying soybean varieties, thinking that the larger the grain size, the higher the yield, but this is actually a misunderstanding.

The larger the grain size, the smaller the number of pods per plant and the number of grains per plant, so the grain weight per plant is not high.

In the case of a certain density, the grain weight per plant is the basis for high yield. In the case of the same planting density of 15,000 plants/mu: the grain weight of a single plant is 15 grams and 20 grams, and the yield per mu is about 150 catties.

Therefore, varieties with small and medium grains, varieties with more pods per plant, more grains per plant, and more grain weight per plant are "rich" varieties.

"Jiadou No. 13", which has passed these hard conditions, falls in the eyes of everyone, and is undoubtedly the "rich and handsome" among soybeans.

The sturdy American soybean breeder Pandel himself obviously has nothing to do with Gao Fushuai, and the soybean varieties he cultivated may be "tall" and "handsome", but they are not compatible with "rich"; like Dick Si always has an inexplicable hostility towards Gao Fushuai, Pandel is also possessed by lemon essence at this moment: "How do other traits perform? For example, disease resistance or something......

The high oil and high yield are also "beautiful", which is not picky, he doesn't believe that he can still perform perfectly.

The improvement of crops has never been for the pursuit of perfection, nor can it be pursued.

If you want to be productive, you may have to sacrifice taste, if you want to be strong, you may have to sacrifice a certain amount of yield, and if you want both yield and taste, you may have to ...... Pray to God.

In Pandel's opinion, "Jiadou 13" definitely has weaknesses...... Right, for example, a noble breed is always a little sickly, right?

Chen Jianzhang smiled lightly: "We have fully tapped the heterosis of wild soybean, re-'picked up' the genes that controlled excellent traits lost in the domestication of wild soybean, and applied them to modern molecular design breeding, and achieved a perfect balance in the key genes of yield important traits such as photoperiod, soybean 100-seed weight, pod number per plant, petiole angle, etc. Well, disease resistance is really not too prominent, and it is only then that it has obvious resistance to common fungal diseases......"

"Is there any heavenly reason!" Pandel forced himself to complain, and the other soybean experts had similar expressions.

Chen Jianzhang undoubtedly admitted that the cultivation of "Jiadou No. 13" was based on wild soybean resources, but then it was a slap in the face to the statement of "good luck".

It is true that wild soybeans have many excellent traits, but during the domestication process, more than 50% of the genetic diversity will be lost in cultivated soybeans. Jiagu's ability to fix the key genes that control important traits in cultivars is not explained by "good luck".

There are more than 30 kinds of soybean diseases and pests, among which fungal diseases are the most, and they can resist common fungal diseases.

People who understand the difficulty of the "little goblin" of soybean evolution mechanism have inexplicably some awe of Kaya's breeding ability.

Pandel also remained silent and became silent.

This is the natural emotion of a breeder when he sees a revolutionary change.

What he was familiar with, what he once learned, and what he was good at suddenly changed.

This is the norm of being hit by the dimensionality reduction of the "Spirit Array".

The most direct effect of the spirit array in breeding is that it can "artificially" screen the genes that control the excellent traits and quickly fix them.

In the eyes of the researchers in the Jiagu laboratory, it is often like this: hey, we have "picked up" polygenes that control traits such as yield and quality, hey, we have completed the coupling between different complex traits, and hey, we have created revolutionary varieties......

It's not just shit luck.

In the Jiagu laboratory and test base, which is shrouded by "all thoughts return to a while", it is easy for researchers to concentrate. With a high degree of concentration, whether it is gradual mutation or strong mutation, it is relatively easy for researchers to identify key regulatory units and shorten the mining cycle of key genes.

The flash of genius and the painstaking efforts of hard-working scholars are as ethereal as smoke and dust under the halo of the golden finger. In this way, the Jiagu laboratory did it step by step, and the correct steps were more than trial and error, and the "green revolution" of soybeans was first realized.

Of course, in the eyes of foreign breeders such as Pandel, this is the high level of research of Kaya.

"Look at the yield. ”

"Yes, it's the most straightforward way to look at production. ”

"The production excites me the most. ”

The international soybean experts who were crushed by the golden finger halo looked at the soybean fields harvested in front of them.

“...... The actual harvest area is 100 mu, and the yield per mu is 443.5 kg according to the standard water content of 13.0%, ......".

Despite its mental preparations, the delegation said several times in a row, "incredible".

Naturally, the Chinese personnel were jubilant, and the others ...... Five flavors are mixed.

Of course, the area of "Jiadou No. 13" to promote planting in Hei Province is large enough, and in order to get more accurate data, the delegation traveled to many places to conduct actual harvest measurements.

"The actual harvest area is 20 acres, and the yield per mu is 415 kilograms......"

"398.9 kg per mu ......"

The latter was measured on one of the farms with the worst production conditions.

But this is even more shocking than the first measured maximum yield.

This is because the record of the highest yield is not too problematic and does not have universal significance.

Referring to the soybean experiments of other countries in the world, in the last century, the island country recorded a yield of more than 300 kilograms per mu, Italy had a record of 400 kilograms per mu, and Missouri in the United States created a mythical record of high soybean yield that the world cannot break so far -- 1,000 catties per mu!

However, these records are based on field management regardless of cost, special light and heat conditions, and special water and fertilizer, and all factors such as time, place, and people have achieved an excellent level.

The Chinese's "Jiadou No. 13", from plots with a high level of production to plots with poor production levels, can basically determine the goal of achieving a large-area output of 400 kilograms per mu.

If the soybean breeders in the United States are still in a tangled mood, the experts of the delegations of Brazil and Argentina have decisively knelt and licked.

In an instant, Chen Jianzhang was surrounded by people who wanted to give them the license to try it in Brazil and Argentina.

Pandel was squeezed to the periphery and thought sourly: Even if it is to cater to the Chinese market, can't you be more reserved?

On second thought, he thought that this was also a moment to witness the history of the soybean industry, and being unreserved was probably the norm.
