  • Title: Population genetic study of Fagopyrum tataricum from Western Himalaya using ISSR markers.
    Author: Kishore G, Pandey A, Dobhal R, Gupta S.
    Journal: Biochem Genet; 2013 Oct; 51(9-10):750-65. PubMed ID: 23743875.
    Abstract:
    Inter-simple sequence repeat (ISSR) markers were used to analyze genetic diversity and relatedness of 15 germplasms of Fagopyrum tataricum. Samples representing 75 individuals were collected from a range of altitudes in the Western Himalaya. The 13 ISSR primers revealed 98.1% polymorphism among populations, whereas average polymorphism was extremely low (2.18%) within populations. The coefficient of population differentiation was 0.9750, with limited gene flow (N m) of 0.0128. The average PIC value of the ISSR markers was high (0.812), with a marker ratio of 0.65 and marker index of 6.66. The genetic diversity of F. tataricum significantly correlated with altitude and gene diversity, Shannon's index, and the percentage of polymorphic bands. The genetic diversity among populations showed broad genetic base and provided a developmental strategy for crop improvement.
