Relevant explanations of technical indicators of crop germplasm resources
Relevant explanations of technical indicators of crop germplasm resources The development of technical indicators of crop germplasm resources is based on the following principles: (1) The main research and breeding needs of crop germplasm resources are taken into account, taking into account both production and market needs. (2) Based on the existing research and work foundation in China, consider future development, and set aside space for expansion. (3) Drawing on international advanced indicators, expanding and innovating on the basis of digestion and absorption. (4) The combination of science, system and practicality. (5) Combination of key technical indicators and method inheritance and innovation. (6) Focus on new technical indicators such as quality (nutritional quality, sensory quality, processing quality, storage freshness, etc.), resistance to pests and diseases, and stress resistance characteristics. (7) Strengthen the development of China's unique resources and specificity technical indicators. Based on the above principles, after summarizing the steps of extraction, testing and development, improvement, testing, technical validation, and peer recognition, technical specifications for 110 crops including food crops, cash crops, vegetables, fruit trees, and forage green manure are presented. 3,824, focusing on new technical indicators such as quality, pest resistance and stress resistance characteristics, integrating and upgrading 1,793 technical indicators, summarizing and improving 9,436 technical indicators, and achieving 15,05 crop germplasm resources technical indicators System specification. In addition, in order to collect and discover the seeds of various crop varieties and scientifically store them so that the germplasm still has original genetic characteristics and high germination power after more than ten years or even decades, we have established crop germplasm resources. The library, which covers different varieties of seeds, is used for variety improvement, breeding of new varieties with high yield, high quality, and strong resistance. According to the different temperature and humidity environments in the library, seed storage buildings can be divided into three categories: long-term storage, which can be stored for up to 30 years; medium-term seed storage, which can be stored for 5 to 15 years, and short-term storage. The library can be stored for 3-5 years. Cosmetic Chemicals,Ingredients In Cosmetics,Chemicals Used In Cosmetics,Cosmetics And Chemistry Jiangyin Lanyu Chemical Co.,Ltd. , https://www.jylanyu-chem.com
