Recently the authors applied the chromosome image analysis in the study of Brassiceae and obtained the following results. 1. The authors apllied the image analysis for the first time in the study of the karyotype of 13 species of Brassiceae. The karyotype data. karyograms, idiograms and karyotype formulae of Raphanus sativus var. raphanistroides and Sinapis alba are reported in this paper. 2. The authors have established the database of chromosome image analysis of Cruciferae, including five genera and 13 species. This is the first database of chromosome image analysis of Cruciferae in China and abroad. 3. The authors applied the database of chromosome image analysis for the first time in the taxonomical studies of Brassiceae, for example, to study the relationship and evolution of some species of Brassica.  As a result they got some karyotype data which might be useful to plant taxonomists.  It is suggested

that the database of chromosome image analysis be very useful to the plant taxonomical studies.
