On 4 june, there was a hot search of the news of a “baby in the branches and eyes”. In recent days, the world's first mixed and successful twig tree, with its parent and its father's eye, has had its first large swathe。
Why mix the twigs with the eye? What difference does it make
Recently, in guangdong county, in the state zenhu zhenhu zheng zone, researchers from the fruit tree research institute of the guangdong academy of agricultural sciences described the “mother” of the zeng zeng tree, the “mother” of the zeng zhuang tree, the “father” of the zeng zhuang tree, which is known as the zhuang tree. The team provisionally named this new species as “goldstone” and took it from the word “growth” and “golden”。
In 2015, senior experts of the guangdong academy of agricultural sciences made the mother book and the eye of the pebbles of late-cooked twigs and tried to cross. The team pollinates the pollen with the eye pollen when it is destroyed, making the female misperceived to be his own pollen, allowing the eye pollen to “take advantage of the opportunity” and obtain hybrid seeds. For 11 years, there was finally a “golder” in this group — a pioneer fruit。
The experiment is based on the world's largest “genetic bank” — the country's petricorn seed reserve. The executive director of the resource library gave an encouraging presentation that two late-literate varieties “born” an early-literate species。
Why did you choose dragon eye as a hybrid? On the outside, the twig looks and tastes are closer to the eye; on the professional level, the twig and the eye are both disease-free and tropical fruits. It is more important that they complement each other。
Zhong zing: the twig, medium and late, is of age and production is very unstable. There's a saying: "what does it mean to be a mother or a child?" that is to say, if it encounters coercion, it has a very strong fallout and saves its own tree. But it's called "the son without the mother." if a dragon's eye is in trouble, it's a dead end, and a tree is a dead end. That's why we're doing this hybrid, trying to combine their qualities. Also, the eye of a dragon, its fruit and meat, is very crumbs, and leads it to its fine sex。
Despite the fact that the twig is the same as the dragon eye, it is different and natural reproductive incompatibilities. Scientists are therefore required to “swindle” the branches of the branches by using the technique of “deep eyes” so that they mistook them for the same kind of pollen. The first of their progenys to produce curdews with fragrance, brilliance, sweetness and fragrance have a clear advantage over pre-literated gills, such as the “red march” fragrance, which is acidic and not very sugary. After taste of it, he said that this new species of twigs had a sense of euphemism。
Q: why do we feel like it's got a bit of an eye gene? Because the mother is a twig, it's soft and smooth, and now we taste it, it's a little bit closer to the frown of the eye, and it's kind of a twig. The taste of the dragon's eyes is not obvious, but the taste of the fruit is there。
In fact, this is not the first of its kind. In 2022, the team of the south china university of agriculture formed the world's first new type of "cracky honey" with cross-eyes and gills, with the eye as its mother. And this is a new species of gills made of gills and dynasty eyes. Both directions were successful, marking a two-way breakthrough in the reproductive separation between the branches and the eyes. So, what are the precious species collected in the country's seedlings that support this breakthrough? When will this be able to enter the consumer's fruit plate
The national seedlings reserve, which has been collected for more than 60 years, preserves nearly 800 species, including black-faced, rags and other species that have disappeared on the market, as well as a large number of species abroad, and is currently the world's largest and most genetically diverse active gene pool. The executive director of the national cedars and plants has informed us that the world's largest stock of breeding materials has been set up, with more than 520,000 hybrids, of which more than 4,000 have already blossomed and over 300 have been selected。
More than a dozen new varieties of high-quality pelican branches, such as the “shin-bing” red lantern, have been bred in this resource nursery and have become market-driven varieties. Today, molecular marking assistive breeding techniques are significantly increasing fertility efficiency。
Zhong zing: we have dug up molecular markers like sugar, corrosive, which, if applied to seedling screening, can shorten the breeding cycle by three to five years. Actually, it's just the beginning, and now we've done almost 800. What do we do with this? It's a seed "chip" that wants to be made of a gill branch, and it's hoped that it will be used for genetic background identification and molecular testing of new varieties。
The birth of the “bigstone” branch, which succeeded in breaking the reproductive separation between the branch and the eye, was an important breakthrough in the breeding of woody fruit trees and demonstrated the innovative energy of the world's largest gene pool. It is explained that, strictly speaking, the twig cannot be called a new breed at this time, but rather an innovative material。
Zhong zing: it is only the first year of the year, and later we have a lot of molecular construction, morphology and trend testing to do, so it is now an innovative material in our resource booth. In the future, if it needs to go to the market, we will have to do regional experiments, evaluation of the fruit quality, to see its instability, including disease resistance, resistance, etc. (testing), and then give it a comprehensive assessment, and eventually we will push it to the market。
Researchers at the fruit tree institute of the guangdong academy of agricultural sciences have spoken out loudly and are currently in the process of testing comparative varieties and are expected to move to the market five or six years later. With the emergence of a new species, the gene pool of the treasures is creating new hope for china's tributary industry。
Spectacular: it takes about five or six years between now and when we move to the market, and i'm sure that when it comes to the market, you're still very fond of it. It matured in mid-may, reaching a sugar level of about 18 per cent, and the scent was more fragrance, a new and more promising species. Thanks to our largest seed bank in the world, we will have more and better babies coming out。
