| Abstract: | The variation rules of average heterozygosities or heteroses in progenies of two and three varieties rotationary crossings were given by recurrent equations and their general solutions,respectively,in this paper.The comparisons among sizes of heterosis components in different crossing patterns were made.These rules and comparisons provided with theoretical references for selection of crossing paterns in heterosis usage. |

| Keywords: | rotationary crossing heterosis recurrent equation general solution |
