Title: ND266: A New Parental Line for Improved Corn Hybrids
Author: Wanner, D.W.; Cross, H.Z.
Description: At time of this writing, corn (Zea may L( is the most important crop in the USA and is one of the five major crops on Earth. 75 million acres of corn are grown in the US alone and generated $20 billion annually. In 1990, corn was not the dominant crop in North Dakota. Yet, it was planted on more than 1 million acres annually in the state and generated in excess of $100 million annually. In 1981, it was estimated that annual corn yields were increasing about 2.3%. Forty years of corn research, single-cross hybrids produced single-cross hybrids and were deemed more productive than synthetic or open-pollinated varieties. Modern hybrids use higher plant densities to increase productivity. Future genetic improvement in corn hybrids in North Dakota was dependent upon the availability of improved, parental inbred lines for use in corn, hybrid research and production. ND266 was the latest inbred line developed in this eighth generation self-pollinated line, a synthetic developed by North Dakota State University.
