中国自1981年起参加了国际水稻遗传评价(INGER)的合作研究。20年来已引入 INGER 提供的1.8万余份各国水稻种质,经全国14点的多年综合评价,从中直接命名推广了35个品种,作恢复系(源)组配了28个杂交水稻新组合,筛选出一大批高产、优质、多抗、耐逆、广亲和等材料,并作为亲本利用于全国各育种项目。据不完全统计,INGER 种质在中国的种植面积累计约1450万 hm~2,增产稻谷544万 t,取得了巨大的经济效益和社会效益。遗传背景多样化的 INGER 水稻种质不仅提高了我国的水稻育种水平,而且丰富了我国的稻种资源宝库。
China has participated in the cooperative research of International Rice Genetic Evaluation (INGER) since 1981. In the past 20 years, more than 18,000 rice germplasm supplied by INGER have been introduced. Through the multi-year comprehensive evaluation at 14 o’clock in the country, 35 varieties were directly named and promoted, and 28 new hybrid rice combinations were set up for restorer (source) A large number of high-yielding, high-quality, multi-resistant, resistant, broad-compatibility and other materials were screened out and used as the parents in breeding programs across the country. According to incomplete statistics, INGER germplasm has an aggregate planting area of about 14.5 million hm ~ 2 in China and an additional 5.44 million tons of paddy rice, which has achieved tremendous economic and social benefits. Genetic diversity INGER rice germplasm not only enhances the level of rice breeding in China, but also enriches the treasure house of rice resources in China.
