Since microspore mother cells showabortion during the first meiotic divison,it is suggested thatthe early male abortion is frequently associated with variousdegrees of impairment to the fertility to the female〓amate.

研究的27个杂种第一代中，有11个组合的产量超过对照或与对照持平，占总组合数的40.74%。在强优势组合中，不育细胞质带来的负效应不足以使F1产量的显著降低，而且通过杂优补偿作用可比对照有所提高。
