    Abstract:

    In order to enhance the seed production efficiency of hybrid wheat,the multi-ovary varieties of homonucler-homoplasmic,heteronucler-homoplasmic and homonucler-heteroplasmic with different Aegilops cytoplasmic were used as the trial material.The penetrance of multi-ovary varieties was investigated in the mature,and the analysis of variance was made using professional data processing software DPS 7.05 for the results.It was showd that the first,second,third grain per floret of homonucler-homoplasmic and homonucler-heteroplasmic multi-ovary wheat have no significant differences in penetrance.However,the penetrance of homoplasmic-heteronucler multi-ovary wheat reached significant levels.The suitable nuclear gene type is very important to raise the penetrance of multi-ovary.
