每穗总粒数与结实一次枝梗数和现存二次枝梗数均密切相关。
Total grain number per spike correlated closely to fruiting primary rachis branch number and existing secondary rachis branch number.
总粒数与其它性状相关不显著。 目标性状的重组率以回交后代为高。
The recombination rate of the target traits was higher in backcross generations than in the other segregation generations.
这可能是由于播种期的推迟，每穗总粒数、每穗实粒数和有效穗显著降低。
The spikelets and the setting grains per panicle and effective panicle number per unit land area all decreased with the delay of seeding times.
