在保证父本花粉够用的情况下,适当增加母本行数,减少父本行数,是夺取玉米制种高产的有效途径。自1982年起,我们开始摸索玉米制种最合适的行比,经过连续几年的试验、示范与应用,得出了科学的结论:平原区大面积制种,正常情况,父母本行比由1:
In ensuring the pollen parent enough, the appropriate increase in the number of maternal lines to reduce the number of patriarchal lines, is to seize the high yield of corn seed production an effective way. Since 1982, we have begun to explore the most appropriate ratio of corn seed production. After several years of experiments, demonstrations and applications, we have reached a scientific conclusion: the large-scale seed production in the plain area is normal, 1:

倒伏是影响水稻高产稳产优质的重要因素之一,倒伏的发生严重限制了水稻机械化收割的推广。白叶枯病是水稻生产中最为严重的细菌性病害,该病侵染源复杂且危害严重,而化学防治效果甚微,培育抗白叶枯病水稻品种是目前最经济有效的途径。稻瘟病已经成为我国六大稻区的共性病害,目前大面积应用的光温敏核不育系的稻瘟病抗性水平低。因此,培育既抗倒伏抗、抗白叶枯病和稻瘟病的光温敏核不育系对我国水稻生产有着极其重要的意义。本研
