举世瞩目的中国杂交稻问世以来,到1983年累计种植5·1亿亩,增产稻谷500多亿斤。杂交水稻增产的大量事实,有力地推动了杂交水稻的进一步发展。杂交水稻米质如何?发展前景如何?这是众人所关注的事情。一般认为,稻米品质包括:精米产量、米粒的大小、形状和外观、蒸煮和食味品质以及营养成份。目前生产上应用的主要籼型杂交稻组合,经米质分析,在碾米、外观、蒸煮和营养品质等方面,一般优于现有常规水稻推广种。近几年供区试的杂交稻组合,平均出糙
Since the advent of hybrid rice of the world, which attracted worldwide attention, by 1983 513 million mu of land was planted and the total output of rice increased by more than 5 billion kilos. A large number of hybrid rice yield increase, effectively promoted the further development of hybrid rice. How is the quality of hybrid rice? What is the development prospect? This is what everyone is concerned about. It is generally accepted that the quality of rice includes: rice yield, grain size, shape and appearance, cooking and eating qualities, and nutrients. At present, the main combinations of indica hybrid rice used in production are generally superior to the conventional rice varieties for rice milling, appearance, cooking and nutritional quality through rice quality analysis. In recent years for the hybrid rice test area combinations, the average out of the rough
