Abstract: Adopting with the methods of William-Clifford (1971) and Orloci(1975, 1978), a comparison of cluster analysis results is made, which indicates that the roles of interaction-and coorelation coefficients in the division of breeding areas of late rice in Zhejiang province are basically the same.In addition, referring with the geographical locations of 11 experimental spots, a preliminary programme for their rational arrangement is put forward.
