چکیده

Molecular markers have been used to predict the genetic variance of segregating soybean populations by measuring the genetic distance between parents. For this purpose we analyzed the genetic distance among six pairwise combinations of four soybean lines grown in Southern Brazil. The AFLP-based distances (AFD) were estimated with 21 primer-pair combinations. Additive genetic variance (D) was estimated in 100 advanced inbred lines for each cross for seven traits, including grain yield, for four sowing dates, and four years. Results showed a low but significant overall correlation (r=0.21*) between grain yield variance and AFD in the average of the four years and sowing dates. Considering the sowing dates the highest correlation was in October (r=0.41*). Significant correlations were also found for five out of the remaining traits evaluated. We found no significant correlations between D and parentage coefficient for all traits evaluated, except for 100 seed weight (r=0.32*).

بررسی تنوع ژنتیکی اکوتیپ‌های گندم سرداری با استفاده از نشانگر AFLP و صفات زراعی

Studying genetic diversity is important because a decrease in genetic variability might result in a reduction of the plasticity of the crops to respond to changes in climate, pathogen populations, or agricultural practices. In this study, 72 Sardari wheat (Triticum aestivum L.) ecotypes were analyzed by AFLP markers and 17 phenotypic characters. Three pairs of EcoRI/MseI primer combinations pro...

In this study, the genetic diversity of 12 Iranian Damask rose (Rosa damascena Mill.) genotypes was studied using amplified fragment length polymorphism (AFLP) markers. Twelve AFLP primer combinations generated 483 polymorphic bands and showed extreme variability and genetic complexity among the studied genotypes. The AFLP analysis revealed a specific amplified fragment for the genotypes collec...

Assessment of Genetic Diversity in Some Iranian Populations of Bunium persicum Using RAPD and AFLP Markers

The genetic diversity of 20 Iranian populations of Bunium persicum has been evaluated with random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers. Fresh leaves of seedlings from each population were used for genomic DNA extraction. Analysis of banding patterns of 15 RAPD primers and 17 AFLP primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Genetic diversity of Iranian melon cultigens revealed by AFLP markers

Iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. The Amplified Fragment Length Polymorphism (AFLP) marker was applied to investigate the genetic variations among five major Iranian melon cultigens (Cucumis melo) and ‘Ananasi’ as a general well-known cultivar. Ten primer pairs were used on 90 indiv...
