摘　　要：本文以中国春小麦细胞核置换到小麦属和山羊草属不同细胞质的同核异质稳定核质杂种为材料,研究了异源细胞质对普通小麦花粉育性及小孢子发育的影响,结果表明;普通小麦中国春的花粉育性不同程度地受到多种异源细胞质的明显影响,其小孢子败育主要发生在四分体时期.In the present paper,using the stable homonucleo—alloplasmic substitution lines obtained by introducing the cell nucleus of Triticum aestivum L.Chinese Spring(CS)into the alien cytoplasms of the Triticum and Aegilops,we studied the effects of allocytoplasms on fertility of pollen and microsporogenesis of common wheat.The results are shown as follows:The fertility of pollen of Triticum aestivum L.CS.was evidently affected to a different extent by some of the alien cyto- pla sms of the Triticum and Aegilops.Its microspores mainly degenerated at the tetrasporic stage.
