Molecular tagging of agronomic traits using simple sequence repeats : informative markers for almond (Prunus dulcis) molecular breeding.

Informative markers are most applicable in breeding purposes, so that can be considered as an initial point to search the genome for the related traits and hold promise for speeding up the fine mapping and identification of genes responsible for variation in agronomic traits. Association mapping as...
