Abstract:

Genetic resources are sometimes called the “first resource” of the natural resources means attention to the vast diversity among and among the plant species. According to International Board for Plant Genetic Resources (IBPGR) descriptors , the 92  almond progenies  variability from ‘Shahrood1’ ×  ‘Shahrood12’  with  their parents,  measure and compared. Principal component analysis (PCA) showed considerable to 30 phenotypic diversity among the almond progenies. The important traits frequency  such as  flowering time, tree size, resistance to frost, growth habit, flower density and  leafing  time  in  all hybrid population  and compare them with  their parents  show  their  asymmetric  distribution  among  them. The  simple correlation coefficients  traits  showed that among the  some of measured traits was a significant positive correlation.  In other hand, the eigenvalue variance percentage and cumulative variance showed the among measure traits five independent factors that their eigenvalue were more than 14, they could justified 42.96% of total variance. Also the study population were separated into four different groups according to their height using cluster analysis performed by Ward’s clustering method based on morphological data. some of progenies likes ‘Shahrood12’ in  first group, some other likes ‘Shahrood1’were in second group and some other that expression of phenotypic traits were additive mode, incomplete dominance or over dominance in third and fourth group.
