Seeds are the foundation of agriculture and more related to food security. Since the founding of the People's Republic of China 70 years ago, China's breeding industry has achieved rapid development, from experience breeding to scientific breeding, ensuring that Chinese rice bowls are filled with Chinese food.
Baodi Huangzhuang is the main grain producing area in Tianjin. After the founding of New China, crops began to be planted here. Sorghum, corn and rice are the main crops in the field. The villager Jiang Yushu recalled that at the time, "the family planted land and the households kept the seeds." Although the output of an acre of rice is only about 200 kilograms, everyone will tighten the belt and leave the fine grain of good color as the seed of the coming year.
People take food as the sky, and agriculture takes the species first. Old varieties can be planted year after year, and disease resistance and yield are decreasing year by year. In 1978, the State promulgated the "Report on Strengthening Seed Work", requiring all localities to quickly establish seed companies and seed bases, and quickly improve the breeding system for improved breeding.
Subsequently, Tianjin began the research and development of new varieties, and the “Jindao 1187†group was also established at that time.
Wang Yuxi and his colleagues searched for *suitable hybrid combinations in 10 million rice ears. Every year in November and February, after the rice cultivation in the north is over, the breeding personnel will continue to rush to the Nanfan base in Hainan, using the unique climate of the region to increase the breeding time and shorten the breeding time.
After nearly 10 years of trial and error, "Jindao 1187" * stable breeding. High yield and high disease resistance also guarantee a good harvest year after year.
Not only is "Jindao 1187", but under the efforts of Yuan Longping breeders, China has also made breakthroughs in hybrid rice. Now the yield per mu has exceeded 1,100 kg. The guarantee of improved varieties enables China to use 7% of the world's cultivated land to feed. 22% of the population.
From the pursuit of high yields to the pursuit of quality, today, people are increasingly demanding the taste of food, which has become a new direction of breeding. When you come to the Tianjin Rice Research Institute Baodi Breeding Base, you will soon be able to smell a rice scent. In the 100-acre experimental field, there are tens of thousands of rice experimental varieties, each with a two-dimensional code next to it, which records its parents, characteristics and other related information.
Today, Su Jingping and his colleagues took over the baton of scientific breeding. In order to support the breeding of new varieties, Tianjin has also allocated funds to support the establishment of a modern molecular testing platform to make breeding research and development even more powerful. In the past, the taste of rice was good. Only when it was grown into food, we know that technicians can select the best combination plan by genetic testing in the seedling stage or even a seed.
The Chinese people's bowls contain Chinese food, relying on Chinese seeds, relying on technological support. At present, Tianjin is constructing a scientific research and breeding base in the Nanfan core area of ​​Ledong County, Hainan Province, with a total planned area of ​​460 mu and a total investment of more than 18 million yuan. The future breeding of new varieties in Tianjin will further accelerate
