An assessment on intraspecific transferability of SSR markers on fennel (Foeniculum vulgare Mill.) varieties

Abstract

The amplification potential of 27 SSR primer pairs originally reported on exotic fennel (Foeniculum vulgare Mill.) was studied on Indian fennel. Only 13 primer pairs developed amplicons (only one amplicon per primer pair) of sizes ranging from 100 to 450 bp. To determine their polymorphic potential, a set of 20 diverse fennel germplasm lines was used. Four primers exhibiting polymorphism, did segregate the 20 diverse lines in 9 clusters. However, these primer pairs did not differentiate between 17 improved varieties of fennel.
