Abstract: Nuclear Institute for Agriculture and Biology has been actively involved in improvement of mungbean for the past two decades. An introgression of large seed size into an indigenous cytoplasmic adapted background has been accomplished following pedigree selection method. Plant architecture has been changed. Early and synchronous maturity has been induced, in addition to high yield potential along with durable disease resistance. True breeding lines possessing desirable combination of economic traits were evaluated in a series of yield trials at NIAB, Faisalabad. The present study discusses the results of these significant achievements and their implication in enhancing and sustaining mungbean productivity.
