Maize is used in an endless list of products that are directly or indirectly related to human
nutrition and food security. Maize is grown in producer farms, farmers depend on genetically …

The time frame of the history of quantitative genetics is similar to Mendelian genetics. The
rediscovery of Mendel's laws of inheritance in 1900 was the basis for determining the …

Maize (Zea mays L.) originated from teosinte (Zea mays L. spp Mexicana) in the Western
Hemisphere about 7,000 to 10,000 years ago. Maize was widely grown by Native Americans …

Advanced-cycle pedigree breeding has caused maize (Zea mays L.) inbreds to become
more-elite but more-narrow genetically. Our objectives were to evaluate the genetic distance …

Maize breeders during the hybrid era (1939 to present) have been extremely successful in
making continuous genetic improvement in commercial grain yield (Fig. 1). Commercial …

The increase in yield attributable to genetic improvement of commercial maize hybrids in
central Iowa from 1930 to 1989 averaged 56 kg/ha/yr (as adjusted to state-wide farm yield …

Improved maize (Zea mays L.) populations and population hybrids can both be profitable
alternatives to commercial single-cross hybrids as well as good elite sources of diverse …

The genetic relationships among 81 maize accessions consisting 79 landraces and two
improved varieties, maintained by farmers in southern Brazil were investigated using …

Maize grain yields in the US started to rise in the late 1930s, concurrent with introduction of
hybrids and improved cultural methods. On-farm yield gains averaged 115 kg ha-1 yr-1 …

Genetic distances were calculated among 37 inbred lines representing a wide range of
related and unrelated elite Corn Belt germ plasm of maize (Zea Mays L.), using 257 probe …
