水稻高产、多抗、优质新品种选育是云南省农科院承担国家和省的“六五”科技攻关项目。参加协作的有大专院校、地 (州、市)农科所、县农推所、良种场以及省有关部门共五十五个单位。“六五”期间通过进行水稻育种攻关,培育出了许多丰产性好、抗性强、米质优的水稻品种(组合),较好地完成了粳、籼、糯、陆稻的育种及推广任务。一、中北部粳稻组。在我国低纬高原地区首次育成耐寒稳产的中秆大穗型品种两个,即“云粳136”和“晋红一号”,适宜高原温冰稻作区的生态环境。“云粳136”在不同年份的区试中,比对照种“云粳九号”增产6.4~41.0%,一般商产1000~1100斤、
Rice breeding, multi-resistance, breeding new varieties of high quality is Yunnan Academy of Agricultural Sciences national and provincial “65” scientific and technological projects. To participate in the collaboration of colleges and universities, prefectural (state, city) Institute of agriculture, county agricultural push, seed field and the provincial departments of a total of 55 units. During the “Sixth Five-Year Plan” period, many rice varieties (combinations) with high yield, strong resistance and high quality were bred by researching rice breeding, and the breeding and popularization of japonica rice, indica rice, waxy rice and paddy rice were completed well task. First, the Central North japonica group. For the first time in the low latitude plateau region of China, two large-scaled mid-stem cultivars with high yield and low temperature were bred, that is, “Yunjing 136” and “Jinhong No.1”. In the regional trials of different years, “Yunjing 136” increased 6.4 ~ 41.0% of the control variety “Yunjing 9”, and generally produced 1000 ~ 1100 kg,
