Seed is the "chip" of agriculture, and seed industry is an important basis for national food security. Small fruit and vegetable seeds are related to the Chinese people's rice bowls and tables, and ensure the stability of the supply of the "food basket" for the whole people. Improved varieties play a key role in promoting grain production. We should make up our minds to promote the seed industry, pay close attention to cultivating fine varieties with independent intellectual property rights, and ensure national food security from the source. China is a big country in fruit and vegetable planting industry, but it is still a long way from a strong country in fruit and vegetable planting industry. Although China's self bred varieties have dominated the bulk vegetable market in recent years, some specific vegetable varieties and high-end varieties still rely on imports for a long time. The "choke" has always been a pain in the development of the seed industry, affecting the safety of the "food basket". The improvement of people's living standards has put forward higher and more diversified requirements for the quality and supply of fruits and vegetables, and also provided opportunities for young fruit and vegetable breeding researchers to display their talents. Engaging in fruit and vegetable breeding research requires professional knowledge of molecular biology and molecular genetics, and mastering advanced biological breeding technology. In recent years, more and more young agricultural experts who have mastered relevant technologies are engaged in tackling key scientific and technological problems in fruit and vegetable biological breeding, giving new impetus to the core technology of fruit and vegetable seed breeding. They have made constant efforts in the basic research of biological seed industry science and technology, the innovation of cutting-edge technology source, the cultivation of breakthrough major varieties, and the "curve overtaking" of unique and high-end varieties. They have made contributions to the realization of independent and controllable seed sources and the protection of national food and seed industry security, so that every high-tech seed can take root and sprout on the land of the motherland, and the people can eat more high-quality fruits and vegetables independently cultivated. For young breeding researchers, engaging in breeding needs to be able to sit on the bench and endure loneliness. Generally speaking, a good new variety needs five or even more years of unremitting cultivation. Even if the latest biological breeding innovation technology is applied, it will take two to three years to obtain an excellent variety or strain. Before being officially put on the market, the phased results of the experiment still need to be trial planted at many points and many times, and the quality, resistance and other target traits need to be improved in the later stage. Therefore, young breeding researchers should not only have the determination and courage to face difficulties, innovate constantly, and climb the scientific and technological peak forever, but also have the perseverance and perseverance to make lifelong efforts. Scientific and technological innovation is the accelerator of breeding innovation, and the accumulated breeding practice is the basis of new variety breeding. Scientific and technological innovation has given us the opportunity to "overtake at curves", but there is no shortcut for breeding. "A ruler and a steelyard, bite with your teeth and stare with your eyes." This is the breeding experience that the older generation of breeding experts taught to our young people. They told us in simple language that the cultivation of new varieties with good quality must be achieved through unremitting breeding practice. It is hoped that the young agricultural science and technology workers in the new era will have the "indomitable spirit". They will not only bravely climb the peak of scientific and technological innovation in the laboratory, but also spread their achievements in the field to the motherland, with a heart of care, patriotism, and ambition to serve the country, and integrate their personal goals into the great Chinese nation
