Assessment of diversity in aloe barbadensis miller using morphological and molecular markers


DOI:10.5958/2230-732X.2015.00060.1

Abstract:

In this study, genetic diversity of 38 accessions of Aloe barbadensis, collected from diff erent parts of India were evaluated using morphological and random amplifi ed polymorphic DNA (RAPD) data. Statistical analysis showed signifi cant diff erences for all morphological characteristics among the accessions, suggesting that selection for relevant characteristics could be possible. The analysis of molecular diversity was used the RAPD technique, with 14 random primers of 10-mer oligonucleotides. RAPD analysis was performed with 14 primers chosen a er a previous screening. Signifi cant genetic variability among those 38 cultivars was obtained both at the morphological and molecular level. This study demonstrated that for determining the genetic variability among some cultivars, the molecular
markers technique is more precise than the morphological traits.
