A new esterase isozyme locus, <i>Est10</i>, with 6 alleles including the null form, has been found in rice by using polyacrylamide gel electrophoresis. Thirty F<sub>2</sub> populations of all possible combinations between 5 different band morphs were studied. The segregation pattern indicated that bands 1, 2, 3, 4, and the null form (0) were allelic with each other. The alleles of Est10 were distributed at different frequencies among different varietal groups of rice and also between cultivated rice and its wild relatives (<i>Oryza rufipogon</i> Griff.). Alleles 1 and 2 were frequently found in Japonica and Indica types, respectively. Allele 3 showed a high frequency in Aus and Boro, both Indica types cultivated in South Asia. Allele 4 was frequent in wild rice <i>O. rufipogon</i>. Judging from the linkage between <i>Est10</i> and RFLP marker RG220 and isozyme marker <i>Est5</i>, <i>Est10</i> is located on chromosome 1. The importance of this locus in evolutionary studies of rice is discussed.<br>
