山东水果面积、产量、效益均位居全国首位,是推动区域经济社会发展的主导产业,我国苹果、梨、桃、李、杏等多种果树的起源演化中心,野生资源极为丰富,但苹果、梨和甜樱桃生产上以引进品种为主,缺乏具有自主知识产权的优质品种,评价利用工作相对滞后。3年来,水果创新团队遗传育种岗位专家紧紧围绕“水果种质资源挖掘、创制与利用”这一主线,采用“研究多样性、保护多样性、创造多样性及利用多样性”的总体研究思路以及 Shandong has the largest fruit area, yield and benefits in China. It is the leading industry in promoting economic and social development in the region. The origins and evolution centers of many fruit trees such as apple, pear, peach, plum and apricot in China are very rich in wild resources. However, The production of pear and sweet cherry is dominated by the introduction of varieties, which lack the high-quality varieties with independent intellectual property rights, and the evaluation and utilization work lags behind. Over the past three years, experts in the field of genetic breeding of fruit innovation team have focused on the main line of “fruit germplasm resources excavation, creation and utilization”, adopting “researching diversity, protecting diversity, creating diversity and using diversity” The overall research ideas as well
