ＫＬ９０８与６个高秆品种杂交，根据Ｐ１、Ｐ２、Ｆ１、Ｆ２、Ｂ１、Ｂ２和部分Ｆ３世代群体株高变异的分析，证明ＫＬ９０８的矮生性系受１对显性矮秆基因控制。基因的表达爱品种的遗传背景影响，显性效应较弱。ＫＬ９０８的基因型暂定为ＤＫＤＫ，ＤＫ与籼稻半矮秆基因ｓｄ－１非等位。作者论述了培育显性矮生系的潜在育种意义。
Based on the analysis of plant height variations of P1, P2, F1, F2, B1, B2 and some F3 generation population, the dwarfing line KL908 was controlled by a pair of dominant dwarf genes. Gene expression Love the genetic background of species, the dominant effect is weak. The genotype of KL908 was tentatively assigned to DKDK, DK and indica rice dwarf gene sd-1 non-allelic. The author discusses the potential breeding of dominant dwarfism.
