The study was taken up with the objective to develop and document descriptors for casuarina genetic resource, which enables the identification of varieties for varietal registration. Descriptors were developed of casuarina genetic resources after surveying the 17 clones Based on the morphological character. Among the clone studied, 15 descriptors were developed and documented, which consist of 7 quantitative characters and 8 qualitative characters.
