摘　　要：本文以递推方程及其通解的形式分别给出了二品种和三品种轮回杂交子代的平均杂合度或杂种优势大小的变化规律，比较了各杂交方式的杂种优势分量的大小。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.
