【摘要】 统计2009—2018年我国南方籼稻整精米率检测数据,表明我国南方籼稻品种的整精米率呈逐年下降的发展趋势,整精米率已经成为优质籼稻发展的限制因素。从品质性状遗传、生态环境、栽培管理、稻米加工等方面分析整精米率的影响因素,提出了相应的对策。结合优质常规籼稻的品种选育和优质杂交籼稻配组的实践,对优质籼稻育种进行展望。提高我国南方稻区籼稻品种的整精米率,对提高籼稻种植效益和加工效益、保障我国粮食安全、提升我国稻米在国际市场中的竞争力均具有重要意义。更多还原

【Abstract】 Through the statistics of the detection data of Indica rice head rice rate in southern China from 2009 to 2018,we found out that the head rice rate of Indica rice varieties was decreasing year by year, which indicated that the head rice rate had restricted the development of high-quality Indica rice.We analyzed the influence factors of quality trait inheritance, ecological environment, cultivation mode, fertilizer and water management, rice processing, and put forward corresponding countermeasures.Combined with the practice of the breeding of good quality Indica conventional rice varieties and good quality Indica hybrid rice, the breeding of good quality Indica rice was prospected.It was of great significance to improve the head rice rate of Indica rice varieties in southern china, to enhance the benefit of Indica rice planting and processing, and to ensure the food security of China and enhance the competitiveness of Chinese rice in the international market.更多还原
