Abstract
Objective] To study the effects of generations of selfing on the quality of summer squash seeds and pollen.[Method] Pollen qual-ity and seeds quality of the generations F2 , F3 , F4 and high inbred F7 were detected.[ Result] The results showed that the generation rate, germination potential and germination index of seeds were declined with the increase of the number of selfing .The degradation of germination rate and vitality index was not significant in F2, F3 and F4, but the germination potential and germination index was declined significantly.All the above indicators showed significant degradation after F7 generation.The pollen viability showed no degradation, but pollen weight was sig-nificantly degraded in F7 .[ Conclusion] The degeneration of seeds quality and the decrease of pollen weight were significant with the increase of the inbred generation,while the decrease of the pollen viability was not significant.关键词
