In order to address the global problem of Vitamin A deficiency, biofortification is considered to be a cost effective and sustainable approach.  The polymorphism in crtRB1gene is associated with b-carotene levels in maize kernels. The randomly selected 10 seeds of selected maize lines in BC2F1 population cobs when analyzed for b-carotene content through HPLC,  showed confirmation of improvement in b-carotene content of 2.37 µg/g. The crtRB1 3’TE polymorphism in BC2F1 population of the cross revealed that the progenies showed segregation distortion(SD). The present study indicated the possiblity to develop a high b-carotene inbred with genetic identity closer to that of the recurrent parent.
