Marker-Trait Association for Fruit Characters in Mango (Mangifera indica L.) Cultivars

In the present study, putative marker-trait associations were identified within a core collection of mango cultivars by simple-sequence-repeat marker based association study. A panel of 48 mango varieties which represented the core collection of the South-West region of India, were characterized at...
