Abstract: The contents of anther released ethylene of isonuclear alloplasmic lines on Mo17 nuclear background with three male sterile cytoplasm T,C,Tang Xu(S) and normal cytoplasm(N)line during the stage of microsporogenesis and development were studied.It was found that at the 1-2 stage(s)before the microspore abortion happened,the released ethylene contents from male sterile anthers were significantly higher than that from normal cytoplasm line.The study of exogenous application of plant growth substances demonstrated that ethrel could remarkably induce the abortion of microspore and pollen of male fertile materials.It was also found that the abortion stage of male sterile lines was partially delayed by the external application of CoCl 2 which is a kind of inhibitor of ethylene synthesis.The possible regulatory role of ethylene on CMS in maize was also discussed.

Key words: Maize, Cytoplasmic male sterility (CMS), Ethylene
