Dr. Chalam rejoined the National Seeds Corporation as its managing director. Although Chalam became well known for the propagation of TN-1 rice, Chalam also played a key role in facilitating the introduction and popularisation of high yielding 'Mexican' dwarf wheat varieties and hybrid maize and groundnut varieties into India. During his stewardship, the National Seeds Corporation of India became a model public sector undertaking both for achieving financial results and for achievement of long-term social objectives.
