Assessment of Genetic Variation Within Indian Mustard (Brassica juncea) Germplasm Using Random Amplified Polymorphic DNA Markers

引用

Journal of Integrative Plant Biology 2008年第4期50卷 385-392页

作者： muhammad Ayub khan Malik Ashiq Rabbani muhammad Munir Saifullah khan Ajmal muhammad Azim Malik Oilseed Research Program National Agricultural Research Center Park Road Islamabad 45500 Pakistan Institute of Agri-Biotechnology & Genetic Resources National Agricultural Research Center Park Road Islamabad 45500 Pakistan University of Arid Agriculture Rawalpindi Pakistan

Genetic diversity among 45 Indian mustard （Brassica juncea L.） genotypes comprising 37 germplasm collections, five advance breeding lines and three improved cultivars was investigated at the DNA level using the random amplified polymorphic DNA （RAPD） technique. Fifteen primers used generated a total of 92 RAPD fragments, of which 81 （88%） were polymorphic. Of these, 13 were unique to accession ‘Pak85559＇. Each primer produced four to nine amplified products with an average of 6.13 bands per primer. Based on pairwise comparisons of RAPD amplification products, Nei and Li＇s similarity coefficients were calculated to evaluate the relationships among the accessions. Pairwise similarity indices were higher among the oilseed accessions and cultivars showing narrow ranges of 0.77-0.99. An unweighted pair-group method with arithmetic averages cluster analysis based on these genetic similarities placed most of the collections and oilseed cultivars close to each other, showing a low level of polymorphism between the accessions used. However, the clusters formed by oilseed collections and cultivars were comparatively distinct from that of advanced breeding lines. Genetically, all of the accessions were classified into a few major groups and a number of individual accessions. Advanced breeding lines were relatively divergent from the rest of the accessions and formed independent clusters. Clustering of the accessions did not show any pattern of association between the RAPD markers and the collection sites. A low level of genetic variability of oilseed mustard was attributed to the selection for similar traits and horticultural uses. Perhaps close parentage of these accessions further contributed towards their little diversity. The study demonstrated that RAPD is a simple and fast technique to compare the genetic relationship and pattern of variation among the gene pool of this crop.
