在以矮、丰、抗、早、优为水稻育种目标的前提下,关于晚稻生态型矮化育种的方向,是我们通过十多年来的育种实践逐步摸索出来的.现将我们的观点比较系统地提出来,与育种工作者共同商榷.(一)回顾历史看我区晚稻品种的现状鉴于六十年代初期我省早稻矮化育种的重大突破,使我区早稻的产量有了较大幅度的增长,相形之下,晚稻的产量反而落后了.这一状况,一直持续至今近二十年之久.晚稻的品种问题,仍处于动荡不定的半落后状态;平原高产地区,至今未能找到一个比较稳定的晚稻当家品种.
Under the premise of short, abundant, resistant, early and excellent rice breeding objectives, the direction of late rice ecological dwarf breeding is gradually developed through breeding practice for more than a decade. Now we compare our point of view Systematically put forward to discuss with the breeding workers (a) review of history to see the status quo of late rice varieties in our region In the early 1960s, a major breakthrough in early rice dwarf breeding breed, so that the yield of early rice in our region has been more substantial The output of late rice has lagged behind .This situation has lasted for nearly two decades.Large varieties of rice is still in a state of turmoil and semi-lag behind.However, the high-yield plain area has not been found so far A more stable late-crop varieties.
