Breeding is based on genetic theory, continuously improves biological genetic characteristics, and cultivatesThe work of better varieties can be called the "chip" of modern agriculture.With the rapid development of science and technology, the agricultural field has also ushered in a quiet revolution -digital breeding.As the perfect combination of modern biotechnology and information technology, digital breeding is gradually changing agricultural production methods, becoming an important tool for global food safety and climate change challenges, helping people to open a more scientific, efficient and sustainable future of agriculture.

"Meeting" breeding to "Hui" breeding
So far, crop breeding can be roughly summarized as 4 eras.

Table type data collection. The high-throughput plant phenotype platform, lidar, high spectrum camera, various goes into battle to carry out "body test" of breeding materials.After obtaining the data, they will be transmitted back to the computer in real time for scientific researchers to check and analyze.
Gene sequencing technology. The core part of the data collection link.Obtain a large amount of genetic information by sequencing the genome of crops.At present, my country has mastered the genomes of many important crops, such as rice, wheat, corn, soybeans, rapeseed, cotton, etc.
Big data analysis. Integrate data, explore the relationship between genetic traits through various analysis methods, and find out key genes related to target traits -such as anti -disease insect pests.
Artificial intelligence and machine learning.Based on the results of data analysis, through artificial intelligence technology construction models, the characteristics of offspring varieties of different genotypes are predicted to provide reference for selection.Can these two kinds of soybean hybrids be more resistant?Artificial intelligence helps us.
In the training room, it is using technology to raise seedlings (the source of "knowledge is the power of power" magazine)
Seeds of "Staying" Technology
Short the breeding cycle. In breeding work, scientific researchers need to continue to observe, record and analyze the table -type features of crops to screen out excellent resources that can be used for breeding.Compared to "a ruler and a scale, bite with your eyes with your eyes", he has worked hard to measure and view the traditional breeding of cropic height, spikes, diseases and maturity. Digital breeding only takes a few days.You can receive automatic upload data.It used to be a few years or even decades to cultivate a new variety, and digital breeding has greatly accelerated this process.
Improve the accuracy of breeding. Excellent genetic genetically accurately positioning excellent genes, through accurate data analysis and algorithm models, more accurately predict cropic traits, reduce unnecessary trials and error, and improve the success rate of breeding.
Adapt to diversified needs. Through the analysis of individual data, personalized production is used to customize the most suitable breeding plan for each crop.Researchers can quickly cultivate varieties that can meet different needs according to the changes in the market and environment, such as disease -resistant pests, drought resistance, saline -tolerant, etc.
From "Meeting" breeding to "Hui" breeding, new technology is constantly adding new vitality to breeding work.In the field, the lush plants are shining with the light of technology.
