我们研究油菜雄性不育二系法(两型系与恢复系配套)获得成功后,于1979年同时对所配的四个组合进行测产,平均折合亩产516.0斤,比对照7055增产34.4%。1980年在上海县颛桥公社集体大队试种(23A×419-0~(-1))F_1和(23A×4190~(-2))F_1二个组合,面积各0.96亩,折合亩产319.3斤和326.8斤,分别比7055增产32.3%和35.4%;在院内的试验,也获得极显著的增产效果。现报告如下。一、材料与方法(一)供试组合:(23A×4190~(-1))F_1、(23A×4190~(-2))F_1、(花叶 A×4190~(-1))F_1、(玉山 A×302-3-1)F_1等四个组合,以7055为对照。(二)田间设计:采用随机区组排列,重复三次,小区长45尺、宽7.5尺,面积337.5
After successfully studying the two-line method of male sterility of rapeseed (two types of lines and restorer system), we measured the four combinations in 1979 and averaged 516.0 kg per mu, 34.4% more than that of the control 7055 . In 1980, Shanghai Zhuanqiao commune brigade trial planting (23A × 419-0 ~ (-1)) F_1 and (23A × 4190 ~ (-2)) F_1 two combinations, the area of 0.96 acres, equivalent to 319.3 kg per mu And 326.8 jin, respectively, increased by 32.3% and 35.4% respectively compared with 7055; the test in the hospital also obtained extremely remarkable yield increase effect. The report is as follows. MATERIALS AND METHODS A. Test combinations: F_1, (23A × 4190 ~ (-2)) F_1, (mosaic × 4190 -1) F_1, (Yushan A × 302-3-1) F_1 four combinations to 7055 as a control. (B) field design: a random block arrangement, repeated three times, the district is 45 feet long and 7.5 feet wide, an area of 337.5
