Genetic polymorphism was studied among thirty Indian mustard genotypes using 20 ISSR primers. This study revealed 156 amplified bands with an average of 7.8 bands per primer out of which 115 were polymorphic. Size of amplified fragments ranged from 100 bp to 1500 bp and number varied from 4 to 14. ISSR data were used to compute genetic similarities based on Jaccrad’s similarity coefficient, it ...

UPGMA analysis, principal component analysis, genetic diversity analysis and genetic distance analysis of RAPD data were used to assess the extent of host specialization in 50 isolates of S. homoeocarpa from five turfgrass hosts. In UPGMA analysis and principal component analysis, the occurrence of host specialization was not readily apparent based on visual inspection. Genetic diversity analys...

Clusters are geographically close groups of related companies or institutions related to a certain area which are inherently more efficient than the other companies due to advantages such as being located in one place, networks, external knowledge, variability of human capital, etc. Today, development through clusters plays a pivotal role in the economic and industrial policies of developed...

Four populations of Anopheles sacharovi Favre occurring in different ecological subregions at altitudes between 353-1,126 m in the Sanliurfa Province of southeast Turkey were compared using morphometric and allozyme analyses. Four allozyme loci were assessed for genetic differentiation among samples from four localities. The similarity phenogram obtained from the allozyme data showed that popul...

A formula is given for a flexible combinatorial clustering strategy, having UPGMA and ISS as special cases. When numerical clustering methods are used to investigate the structure of taxonomic groups, it is common practice to try several methods, having different clustering intensities. For example, one might use single linkage (weak), UPGMA (medium), and complete linkage (strong) (Sneath and S...

Indigofera pseudotinctoria Mats is an agronomically and economically important perennial legume shrub with a high forage yield, protein content and strong adaptability, which is subject to natural habitat fragmentation and serious human disturbance. Until now, our knowledge of the genetic relationships and intraspecific genetic diversity for its wild collections is still poor, especially at sma...

Thirty eight ecotypes of watermelon were collected from different parts of Iran. After the preparation of the field, these eotypes were cultivated in a completely randomized block design with three replications. In order to invest-igate genetic diversity, genomic DNA samples were extracted from leaves and Polymerase chain reactions were optimized using 14 SRAP primer pairs. One hundred thirty s...

In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...
