The Shadow Sun

On February 9, 1914, the wheat ecological breeding expert Sharpong Yan was born.

Xi Jinping's lifetime and wheat breeding ended the unresolved line, known as the father of northeast spring wheat breeding, cultivated more than 50 excellent spring wheat varieties currently spread throughout the northeast, solved three major problems for northeast wheat resistance, strong adaptability, stability of yield, thus rewriting the history of northeast wheat, bringing rich harvesting hope for farmers. These excellent varieties have accumulated a planting area of 1 billion acres, so that the varieties of northeast spring wheat have been renewed three times over the course of the 40 years, creating economic benefits of more than 200 billion yuan.

Main achievements

Xiaoping Yang established advanced scientific research methods such as the combination of hybrid breeding and anti-disease identification, in the early 1950s, selected cultivation promoted China's first batch of "Strong and Strong" anti-roasting wheat new varieties, so that local wheat from "dangerous crops" to "stable crops."In breeding practice, Xiaoping Yang studied in depth the main ecological differences and interrelationships of wheat varieties grown in various ecological areas, combined plant ecology, crop genetics and wheat breeding biological, established the theory and method of spring wheat ecological breeding, and opened a new path for the selection of new varieties of crops.

First proposed the application of ecological view of the selection of varieties of the whole set of practices, the cultivation of a large number of "K" excellent spring wheat varieties suitable for the different ecological conditions in the province of Chengdu and the ancient Mongolia region, among which "Kwon 3" and "New Chengdu 9" the largest plantation area is more than 10 million acres, has made an important contribution to the development of China's spring wheat production and the construction of commodity base. has been selected several times as the province's model of labor, the province, the national People's Congress representative. received Chengdu province scientific and technological achievements award, agriculture and fisheries Ministry improvement technology first prize, national invention second prize and many other awards.
