Microsatellite markers based association mapping for yield contributing traits in exotic accessions of barley (Hordeum vulgare L.)

Published on

Linkage disequilibrium (LD) based association mapping
(AM) was examined for 48 barley accessions (
Hordeum
vulgare
L.) introduced from ICARDA in India, by a set of
polymorphic SSR markers for eight agro-morphological
traits. Marker trait association mapping was performed by
MLM (Q+K) model and has also been validated using CMLM
model. A total of twelve significant marker traits
associations were found in the current study at
p < 0.001.
Associations of the maker, ABC252 on chromosome 2H
with DH and TGW and marker Bmag273 on chromosome 7H
with SL were novel ones. The present study provides a set of
candidate SSR markers for future QTL/marker assisted
selection of these traits in barley
