高纬度特短生育期油菜育种获突破

Core Insights - The research team led by Academician Wang Hanzhong from the Chinese Academy of Agricultural Sciences has achieved significant breakthroughs in breeding high-yield, high-oil spring rapeseed varieties with a very short growth period of only 100 days, specifically designed for high-latitude regions [1] - The newly developed variety "Beiya You 1" has demonstrated a theoretical yield of 284.75 kg per mu in demonstration areas, which is a 93% increase compared to the average yield of local varieties [1] - The new varieties exhibit excellent cold resistance, capable of withstanding temperatures as low as -5°C during the seedling stage, making them suitable for the unique climatic conditions of the North Asia region [1] Industry Developments - The introduction of the "Bt (biotechnology) + Eb (ecological breeding)" theory and technical system marks a new breeding model for oilseed crops in high-latitude cold regions [1] - There is a rich reserve of saline-alkali land resources in China's high-latitude areas, which can be utilized for the development of short-growth-period spring rapeseed production [1]
