چکیده

Green gram is also one of the important pulse crops. Conventional breeding methods are very much difficult to utilize in the development of new genotypes. Hence incorporation of the molecular approaches along with the conventional techniques is most powerful method. Evaluation of the available wild accessions are more useful for selecting desirable gene sources. Genetic diversity analysis place an important role in this purpose. For this molecular analysis of selected 18 accessions in greengram (representing all nine clusters) was carried out through RAPD markers. Out of ten primers used nine were polymorphic in which the primer OPS-11 exhibited 100 per cent polymorphism. The value of similarity indices 0.72 to 0.91 indicates high genetic similarity among the selected accessions at molecular level.

Genetic Diversity of Bread Wheat (Triticum aestivum L.) Genotypes Using RAPD and ISSR Molecular Markers

The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...

Molecular Characterization of Unknown Potentially Salt Tolerant Olive Genotypes Using RAPD Markers

Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and discriminate among 17 unknown genotypes (considered potentially salt tolerant) and 16 known olive cultivars. Fifteen decamer primers which produced 38 reproducible polymorphic bands in the genotypes were selected for analysis. The RAPD markers resulted in 93 distinct banding patterns. Based on either ...

Evaluation of Genetic Diversity among Some Common Fig Using RAPD and ISSR Molecular Markers

The common fig (Ficus carica L.), one of the most important fruit species, belongs to Moraceae family and is widely distributed in Iran. In this study, genetic variations among some genotypes of common fig collected from six different regions of Ilam province (Iran) were evaluated based on RAPD and ISSR markers. A total of 73 and 29 alleles were produced by 14 RAPD (with their sizes ranging fro...

Study of genetic diversities and relatedness of Iranian citrus genotypes using morphological and molecular markers

Having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. In present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and RAPD markers. Significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
