Yangtze River Daily Great Wuhan Client reported on April 26 that rapeseed yield exceeded 400 kg, with an oil content of more than 50%, setting a new record for rapeseed high yield in the Yangtze River river basin. On the morning of the 25th, through on-site production measurement and acceptance, the expert group determined that the new rapeseed variety "Central Oil Miscellaneous 501" has the advantages of dense planting, high yield, high oil, high quality, disease resistance, anti-fall, crack resistance, and suitable for mechanized harvesting, achieving a major breakthrough in the core technology of my country's rapeseed industry's green revolution. This is also the first time that the per mu of winter rapeseed in my country has exceeded 400 kilograms.
"Central Oil Miscellaneous 501" that broke multiple records.
This variety was bred by the team of academicians of the Institute of Oil Materials of the Chinese Academy of Agricultural Sciences through more than ten years of research and selection. At the site of the National Rapeseed Industry Technology System Comprehensive Experiment Station of the Xiangyang Academy of Agricultural Sciences, Hubei Province, the dense rapeseed is even more crystal clear and green after being washed by spring rain overnight. "Central Oil Miscellaneous 501" stands upright and does many new varieties of experiments and the control group rapeseed, which seems a little different.
The executive chief researcher of the team participating in the production measurement introduced that a major feature of "Central Oil Miscellaneous 501" is dense planting. Generally, 20,000 canola plants are saturated if planted per mu, and it can be planted to 30,000 plants, an increase of 50%, and everything is normal for flowering, pods and fruiting. He described that "Central Oil Corporation Miscellaneous 501" is a "team player". The indicators that are taken out individually are not necessarily superior, but when they are combined, they will widen the gap. In the national new variety test, the oil content of "Central Oil Miscellaneous 501" has reached 50.38%, making it the highest oil content, with an oil yield per mu increased by nearly 27%, and its quality is better than the international double low standards.
production test site.
The production measurement began. The researchers randomly drew a 1-meter square area in the field, picked up the rapeseed plants inside one by one, carefully picked off the seed pods on it, counted and weighed them, and then peeled out the rapeseed and weighed them. According to the calculation formula for rapeseed yield and oil output, the rapeseed yield is 419.19 kg/mu, and the oil output is converted to 211.57 kg/mu. The expert group led by Professor Li Ghana from Southwest University said that the success of "Central Oil Miscellaneous 501" marks the operation of dense and high-yield rape breeding. Finding yield by dense planting will also be an important path for the development of my country's rapeseed industry in the future, and it is expected to double the oil production per unit area.
Wang Xinfa said that the next step of "Central Oil Miscellaneous 501" will test its adaptability, and this year it plans to promote the planting of 100,000 mu. According to past experience, large-scale planting will be achieved in three to five years.
It is reported that rapeseed, as my country's largest oil crop, accounts for about 50% of the domestic edible oil market, but my country's edible vegetable oil has an external dependence of up to 70%, and the import sources are highly concentrated, so supply security is at risk. Academician Wang Hanzhong's team of the Institute of Oil Products proposed the "Double 50" project of rapeseed, and planned to achieve more than 50% oil content of rapeseed varieties by technology innovation and increase oil production by 50% by around 2030. The reason why "Central Oil Miscellaneous 501" is named so because it is the first phased achievement of the "Double 50" project. The first "top student" graduated. Wang Xinfa said that the first goal of oil content exceeding 50% has been achieved. The next step will continue to accelerate breeding progress on this basis and strive to increase oil production by 50% as soon as possible.
