异交结实潜力是指不育系在保证有充足外源花粉供应的条件下的最高结实率.本研究表明，不同的水稻光温敏核不育系具有不同的异交结实潜力，异交结实潜力的高低受遗传、环境及遗传与环境互作的共同影响；环境对不育系异交结实潜力影响的主因是温度，其作用的敏感时期是异交籽粒灌浆充实的前期；不育系的异交结实潜力也是决定制种产量的重要因素之一.

Outcrossing-seedy potentiality is the seed setting rate undersupplying PTGMS with adequate foreign pollens. The results indicated: 1) It existed differences in outcrossing-seedy potentiality among different PTGMS. Outcrossing-seedy potentiality was affected by inheritance， environment and the interaction of inheritance×environment. 2) In environment conditions, environment temperature was the main factor which affected outcrossing-seedy potentiality. It's sensitive stage occurred in the early stage of milking and seed setting for outcrossing seed. 3) Outcrossing-seedy potentiality of PTGMS was one of important factors which affected the yield of hybrid seed production.
