摘要
水稻发育进程中，主茎增叶速度的遗传表现为动态过程，遗传模式在发生变化；显性效应比甲性效应更重要，且加性效应变异较大；各时期均不同程度地表现超显性；控制主茎增叶速度并显示显性的基因组数、狭义遗传力等也存在较大差异。
The inheritance to the rate of leaf incremcnt of main stem was a dynamic proccss in the growthstage of ricc. The gcnetic modc1c changed in the various growth stage. The dominant effect Performedmore important than the additivc cffect on the composition of genetic effcct in the whole growth process.The importance of the additive cffcct showcd grcatcr changcs and performed superdominance with varydegrees in each growth stage. A distinct diffcrencc was exsited in controlling thc rate of 1eaf increment ofmain stem, showing thc genc numbers of dominant and restricted hereditary capcity etc.
