Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...

tomato as a highly nutritious vegetable crop is widely grown in the world. hybrid seed is preferably used for tomato production. identification of superior hybrid combination is one of the most important steps in the hybrid breeding programs. breeding of high yielding hybrids is expensive and involves testing large numbers of hybrid combinations in multi-environment trials. successful predictio...

genetic diversity relationships of 50 isolates of cytospora schulzeri on apple from different parts of the semirom region were analyzed using 15 polymerase chain reaction (pcr) based markers, 7 random amplified polymorphic dnas (rapds) and 8 microsatellite primed polymerase chain reaction (mp-pcr). using 7 selected rapd primers 113 bands were generated, of which 81 bands were polymorphic (71.7%...

Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...

in this study, genetic diversity of 30 accessions of the fennel from different cities of iran and other asian and european countries were assessed by using 20 selective aflp primers. totally, from 1127 observed bands, 250 bands were polymorph. e11-m20 primer with 20 bands, also e46-m35 and etg-m20 primers with 8 bands indicated the maximum and minimum numbers of polymorphism, respectively. acco...
