中國(guo)工(gong)程院(yuan)院(yuan)士戴(dai)景瑞在對浚單20鑒定時認為：“浚單20育種目標明(ming)確，技(ji)術路線(xian)科學(xue)合理，種質創新和品(pin)種選(xuan)育有重大(da)突(tu)破，實現了良種良法配套，為我(wo)國(guo)玉米生產作出了重大(da)貢獻，成果整體(ti)達到國(guo)際先進水平。”
中國(guo)工程院院士方智遠評(ping)價浚單20：“第(di)一，從創新(xin)角度來說，它的種(zhong)(zhong)質創新(xin)非(fei)常(chang)好(hao)；第(di)二，從內容上講(jiang)，它非(fei)常(chang)全面，既有(you)育種(zhong)(zhong)，又(you)有(you)配(pei)套栽培技術(shu)；第(di)三，它的效(xiao)果(guo)非(fei)常(chang)好(hao)，效(xiao)益非(fei)常(chang)高，為我國(guo)玉米產(chan)業甚至對(dui)農業生產(chan)的發展，作出了很大貢獻。”
