在水稻育种工作中,必须注意边际效应。若处理不好,往往会前功尽弃。据报导,水稻的边际效应在产量比较试验中,小区最边行的单株产量与小区内任何一行的单株产量差异显著,而小区内第二行的单株产量与第三行以内任何一行的单株产量差异均未达显著水平。但对水稻品种(系)间边际效应的差异,以及边际效应与水稻植株形态的关系,少见报导。本研究探讨了水稻品种(系)间边际效应的差异及边际效应与植株形态的
In rice breeding, we must pay attention to the marginal effect. If not handled properly, often give up. It is reported that the marginal effect of rice in the yield comparison test, the plots of the plots on the side of the line with any significant difference between the yield of any single line within the district significant difference between the plots of the second line of production and the third line of any line The yield per plant did not reach significant level. However, it is seldom reported on the difference of marginal effect between rice cultivars (lines) and the relationship between marginal effect and rice plant morphology. This study explored the differences in marginal effects and marginal effects of rice varieties (lines) and plant morphology
