Phoenix belongs to the family Arecaceae (Palmae) and sub-family Coryphoideae. Date palm is cultivated in arid and semi-arid regions worldwide. It is one of the classical old world fruit along with the olive and fig. Date palm is dioecious in nature which refers to a species having separate male and female plants. Sexual phenotype is a particularly majorissue in dioecious plants that are cultivated for agricultural purposes.A major problem for farmers is to identify gender at an early stage so that they cannot cultivate large number of productive female trees with only a minimal number of male trees. At the maturation stage of the date palm tree, it is easy to identify the male and female flowers but it takes 5- 7 years.EnglishThesis
