This study aims to determine how much genetic and phenotypic variation exists in five different varieties of Egyptian Cotton using Inter Simple Sequence Repeats (ISSR) as a molecular marker and twenty-one quantitative and qualitative morphological traits as a taxonomic source in the development and evolution of this plant. Eleven ISSR primers were used, producing a total of 134 bands with a polymorphism percentage of 67%. Positive and negative significant Pearson correlations were found among the studied morphological traits in line with the phenotypic correlations in some characteristics. The genotypic correlation coefficient was higher in magnitude than that of phenotypic correlation. The five varieties were grouped into two major clusters using the UPGMA method based on morphological and ISSR analysis. The first one included G86 and G89 varieties, while the second cluster include...

Fruit anatomy is one of the significant taxonomic tools that recently used. Caryopsis fruit of grasses represents an important source of starch-rich food. Sections of each taxa fruit were examined, measured, photographed and line drawings supported. The main parts of a section are seed coat cells, aleurone layer and the starch endosperm. The cotyledon cells, scutellum, are also defined in various types. Different section dimensions were measured, generally the section dimensions found to be related in some means to the fruit size.
