与野败型杂交稻相比，多数红莲型杂交稻育性和结实率变化较大，该变化与气温密切相关。气温对育性的影响在花粉发育的单核至完熟期，而对结实率的影响则在抽穗期。实用型的红莲型不育系，气温对其育性的影响只局限在染败花粉率的增减上，这样的不育系可以早晚两造繁制种。在红莲型杂交稻中，并不缺乏育性和结实率稳定、对气温变化反应不敏感的强优组合，这样的杂交组合可以扩大其种植区域和范围。
Compared with the wild-type hybrid rice, most of the lotus hybrid rice fertility and seed setting rate changes, the change is closely related with the temperature. The effect of temperature on fertility is from mononuclear to maturity of pollen development, while the effect on seed setting rate is at heading stage. Practical red lotus-type sterile lines, the impact of temperature on its fertility is limited to increase or decrease in pollination rate of streaks, such a sterile line can be made sooner or later to reproduce. In Honglian hybrid rice, there is no shortage of strong combination of fertility and seed setting rate, insensitive to the change of temperature. Such a hybrid combination can expand its planting area and range.
