To Genes bank visitors

We have at our disposal a large number of vine-cactus genotypes whose characteristics and behaviors we have been investigating since 1984. We recently decided to upload these descriptions to my homepage for the use of anyone who is interested. The different species in our possession constitute three genera, Hylocereus, Selenicereus, and  Epiphyllum. We also found that interspecific and intergeneric hybrids can be feasibly produced.  In such cases that we were unable to define the species, the genus name is followed by “sp”.

The intergeneric hybrids include a cross between S. megalanthusand S. grandifloroussince some people believe that S. megalanthus belongs to the Hylocereus genus. Although our S. megalanthus collection includes over 30different clones, they are all phenotypically identical, and therefore, pictures of only one genotype are shown. Two additional identification numbers were included for each genotype to help us distinguish among the genotypes and to allow the lineage of the offspring to be easily traced back to the parent plants.

Our data is presented in a form of Power Point Presentations (saved as PDF files).  Each document represents a different group of genotypes.  The first page of each document contains a table with a description of the clones shown in that specific document.  The table is followed by pictures of the different clone parts, including flowers and fruit. After the pictures, seasonal weekly flowering distribution as a percentage of the total flowers produced in that season is specified.  The last page of each document represents the monthly flowering and ripening of the various clones.  Only the Epiphyllum genus document has all its tables & figures presented in the first page.

Documents for the following genotypes are included


1.Hylocereus undatus

2.4001-4192 other Hylocereus

3.4002-4200 Hybrids of Hylocereus

4.Intergeneric hybrids



As our photographic records of certain genotypes are incomplete, we hope to process and upload all missing pictures during the coming season. 

All this information was collected in Beer Sheva (capital of the desert) Israel, situated @ 31° 15' N and 34° 48' E hence, is correct only for that location.

The information on this website was collected, analyzed and prepared by Mr. Joseph Mouyal an agronomist of Ben-Gurion University of the Negev.
