Maize × Teosinte Hybridization

1994
The greatest part of the genetic variability of maize has been caused or maintained by the introgression of wild germplasm, especially of the taxa closest to the cultivated species: the teosintes. There exists good documentation regarding the existence of F1 Hybrids and advanced generations, derived from the same, produced by natural Hybridizations ...

Tillage × Maize Hybrid Interactions

Agronomy Journal, 2006
Continuous maize (Zea mays L.) yields may be depressed with no‐tillage (NT) compared with conventional chisel and disking systems (CD). Shallow or deep in‐row tillage (ST and DT, respectively) may help alleviate this yield reduction, whereas some hybrids may be better adapted to NT. We therefore evaluated five maize hybrids with NT, ST, DT, and CD from

Transferring hybrid maize technology

Food Policy, 1988
Abstract Developing countries have tried a variety of policies concerning new technology as a source of agricultural growth; there is still much debate on which is the most efficient. More study of private methods of technology transfer is needed.

New maize × Tripsacum hybrids for maize improvement

Euphytica, 1979
Approximately 27 000 maize x tripsacum pollinations were made and 19 hybrids were identified. Fourteen of these hybrids were of the classical type, which possesses the full gametic complement of chromosomes from each parent. These hybrids are more like tripsacum than maize.

Biogas production from maize hybrids

Biomass and Bioenergy, 2010
Abstract There is an increasing world wide demand for energy crops and animal manures for biogas production. This research project was aimed at optimising anaerobic digestion of maize, using a laboratory digester, and finding out which maturity class of corn and which hybrid of a particular maturity class produces the highest rate of biogas and ...

Transmission of maize chromosome 9 rearrangements in oat–maize radiation hybrids

Genome, 2004
Oat–maize radiation hybrids are oat (Avena sativa L.) plants carrying radiation-induced subchromosome fragments of a given maize (Zea mays L.) chromosome. Since first-generation radiation hybrids contain various maize chromosome rearrangements in a hemizygous condition, variation might be expected in the transmission of these rearrangements to ...

Developing hybrids from two improved maize populations

Theoretical and Applied Genetics, 1974
The performance of a group of 49 hybrids from seven elite maize (Zea mays L.) lines selected from each of the two populations, BSK(S)C5 and BSSS(R)C5, was compared with the varietal-cross hybrid of the source populations and with elite single-cross hybrids. Both populations had been improved by five cycles of recurrent selection.

THE EXPERIMENTAL BASIS FOR HYBRID MAIZE*

Biological Reviews, 1946
SummaryThe development of superior maize hybrids and their rapid acceptance by farmers constitutes one of the most important advances in American agriculture within the past century. In 1944 hybrid maize plantings occupied approximately 83 % of the maize acreage in the Corn Belt.

Resistance of South African maize hybrids to maize streak virus

South African Journal of Plant and Soil, 1991
Data from maize cultivar trials at Vaalharts over a five-year period were used to evaluate the level of resistance to maize streak virus (MSV) in commercial maize hybrids, and to determine the potential value of such resistance. Maize hybrids presently grown in South Africa showed varying degrees of resistance to MSV.

Development of maize hybrids resistant to maize streak virus

Crop Protection, 1992
Abstract Established plant-breeding practices were used in the development of maize ( Zea mays ) inbreds (homozygous plants) resistant to maize streak virus (MSV). These were then crossed in various combinations to produce MSV-resistant hybrids. Recently, 150 white inbreds were infected with the virus in a field experiment.
