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]

Core Insights - The research team from the Chinese Academy of Agricultural Sciences has successfully developed high-yield and high-oil spring rapeseed varieties suitable for high-latitude regions, specifically "Beiya Oil No. 1" [1][2] - The development aims to address the challenges faced in the North Asia region, where harsh natural conditions limit the growth of oilseed crops [1] Group 1: Research and Development - The collaboration between the Chinese Academy of Agricultural Sciences and the Inner Mongolia Academy of Agricultural and Animal Husbandry Sciences has led to the establishment of the "North Asia Rapeseed and Soybean Innovation Center" [1] - The center utilizes a robust biological breeding technology platform capable of producing 100,000 double haploid lines annually, introducing a new breeding model combining biotechnology and ecological breeding [1] Group 2: Agricultural Impact - "Beiya Oil No. 1" has demonstrated a theoretical yield of 284.75 kg per mu in demonstration areas, representing a 93% increase over the average yield of local varieties [2] - The new variety has a growth cycle of only 100 days, with sowing on May 6, flowering by mid-July, and harvest by mid-August, along with excellent cold resistance [2]

Core Insights - The research team led by Academician Wang Hanzhong from the Chinese Academy of Agricultural Sciences has achieved significant breakthroughs in breeding oilseed rape varieties suitable for high-latitude regions, specifically in Inner Mongolia [1] Group 1: Breeding Achievements - Five new oilseed rape varieties, including "Beiya You 1," have been developed, which require only 100 days for the entire growth period [1] - The theoretical yield of "Beiya You 1" in the demonstration area reached 284.75 kg per mu, representing a 93% increase compared to the average yield of local varieties [1] Group 2: Adaptability and Quality - The new varieties exhibit excellent cold resistance, capable of withstanding temperatures as low as -5 degrees Celsius during the seedling stage, making them well-suited for the local climate [1] - The quality of the new varieties meets international dual-low standards, with an average oil content of 48.36% expected from the two parent lines in 2024 [1]
