Development of functional marker for distinguishing Glu-B3b allele of LMW-GS found in Indian common wheat cultivars

► Cloning and characterization of Glu-B3b gene from wheat cultivars. ► Development of Glu-B3b specific markers. ► Glu-B3b specific markers validated in diverse set of wheat cultivars. ► The identified marker has potential in wheat breeding and germplasm screening.
