The high-yielding hybrid rice "Zhenyou" series and the high-oil-bearing "double-low" rapeseed "Zheyou" series are the current crop varieties known throughout the country. The farmers used these seeds to produce high-quality, high-yield, and increased production and income, but we What may not be known is that, behind the cultivation of these excellent crop seeds, thousands of excellent germplasm resources cannot be separated because these varieties are actually extracted from these germplasm resources and are selected through hybridization and other techniques. Therefore, the use of crop germplasm resources to collect and protect crop germplasm resources plays an important role in agricultural development.
The germplasm resource bank of crops is a library equipment that is dedicated to the collection of crop germplasm resources. We know that many kinds of quality resources exist in the form of seeds, and that seeds stored in the external environment are subject to aging due to weather conditions. To reduce its use value, but the use of crop germplasm resources to collect and store these germplasm resources can effectively protect it from external harsh environments, and achieve long-term safe storage, allowing it to go through years and dozens of After the year, it can still be used as an excellent genetic material for us.
With the promotion and application of crop germplasm resource banks, more and more germplasm resources have been collected and protected, which has also helped breeding experts to intensify these excellent germplasm resources, such as the use of crop germplasm in Zhejiang Province. More than 2,000 germplasm resources have been collected and protected by the resource bank, ranking top in the country in terms of the ability to select and breed crops such as alfalfa hybrid rice, conventional early-late rice, rapeseed, tomato, broccoli, cowpea, and Zhejiang Bawei Chinese herbal medicine. High-yielding hybrid rice “Yanyou†series and high-oil “double-low†rapeseed “Zheyou†series varieties are well-known throughout the country and have made important contributions in agricultural production and occupy the leading power for innovation.
