吉林省水稻品种演变与生产过程分析

Analysis on Evolution of Rice Varieties and Production Process in Jilin Province

介绍了建国前后水稻品种演变历程和水稻生产发展历程:建国前水稻是吉林省的次要粮食作物,当时多用外来品种,抗逆性不强,产量不高不稳,品种不良限制了水稻种植面积的扩大;建国后,伴随遗传育种技术的改进与提高,水稻品种不断更新换代,促使水稻产量迅速提高,水稻种植面积迅速增加;吉林省的水稻生产发展历程与品种更新换代历程完全吻合。

The evolution of rice varieties and production process before and after the foundation of the People＇s Republic of China were introduced.Rice is an minor food crop before the foundation of the People＇s Republic of China,the alien species is mostly used to plant,its adversity resistance is weak,its yield is low and instable.Undesirable species limit extending to rice planting areas.With the development and improvement of technology of genetics and breeding,rice varieties are upgrading continuously which can improve the rice production and increase rice planting area quickly.There is exactly matched between development of rice production and the upgrading course of rice variety in Jilin Province.
