Analysis of genetic diversity of salt-tolerant alfalfa germplasms

J. Jiang, Yang, B. L., Xia, T., Yu, S. M., Wu, Y. N., Jin, H., and Li, J. R., “Analysis of genetic diversity of salt-tolerant alfalfa germplasms”, vol. 14, pp. 4438-4447, 2015.

Random amplified polymorphic DNA technology was used to analyze the genetic diversity of 25 salt-tolerant alfalfa varieties using 30 different primers. Results showed that the percentage of polymorphic loci between single-plant DNA was 81.52%, and that between mixed DNA of various varieties was 61.65%. Compared to the mixed DNA samples, single-plant DNA samples can better reveal the level of genetic variation among and between alfalfa varieties.

Association of AFLP and SCAR markers with common leafspot resistance in autotetraploid alfalfa (Medicago sativa)

Y. Wang, Bi, B., Yuan, Q. H., Li, X. L., and Gao, J. M., “Association of AFLP and SCAR markers with common leafspot resistance in autotetraploid alfalfa (Medicago sativa)”, vol. 11, pp. 606-616, 2012.

To identify amplified fragment length polymorphism (AFLP) markers associated with resistance or susceptibility of alfalfa to common leafspot (CLS) caused by the fungus Pseudopeziza medicaginis (Dermateaceae), bulked segregant analysis was conducted based on an F1(M × M) population of 93 plants and a BC1S population of 91 plants. Three AFLP markers, ACTCAAR206, TAGCACR185, and GGACTAS264, were found to be associated with CLS resistance or susceptibility.
