Scientific research builds foundations to help flowers and seeds achieve comprehensive catch-up

Peanut is an important oil crop and cash crop and occupies an important position in the national economy

Set direction - high yield

In 2021, China's peanut planting area will be 71.

"Cultivate high-yield and high-quality peanuts, and have our own leading varieties

Li Yurong, 66 years old, has devoted himself to the research of flower breeding for 37 years in the Peanut Research Institute of the Institute of Grain and Oil Crops, Hebei Academy of Agriculture and Forestry

To breed, how to choose the direction? There are more people and less land, and there is a shortage of arable land resources.

The quality of genes determines the quality of a seed

It generally takes 8-10 years to complete the entire breeding process from determining the breeding goal, selecting the breeding method, selecting the breeding parents, assembling the hybrid combination, implementing the selection of the progeny, carrying out the ecological test, and finally going through the registration procedures

At that time, there was no ready-made experience in flower breeding for reference.

Cold and summer come and go, all the hardships come and go

Re-research - better quality

A successful self-reliance breeding is only the first step

Zhang Xinyou, academician of the Chinese Academy of Engineering, president of the Henan Academy of Agricultural Sciences, and chief scientist of the National Peanut Industry Technology System, has led the scientific research team to cultivate more than 50 high-quality peanut varieties in the "Yuhua" and "Yuanza" series since 1984

After years of research, Zhang Xinyou's team has cultivated more than 10 high-oil peanut varieties with an oil content of more than 55%, with a maximum oil content of more than 59%.

　　In the past, the growth period of peanuts in the main producing areas of Huanghuaihai in China was more than 130 days, and the growth period of wheat and peanuts overlapped for a certain period of time.

　　High oleic acid peanuts refer to peanut varieties with an oleic acid content of more than 75% or a ratio of oleic acid to linoleic acid of not less than 10

　　Statistics show that from 2018 to 2020, the number of high-oleic acid peanut varieties bred in China has grown by leaps and bounds, increasing from 9 to 175 in just 3 years

　　The country is based on agriculture, and agriculture is based on seeds
