Abstract. Hybrid cultivars are the first generation (F 1) progeny of a cross between two or more selected and genetically diverse parents, and these exploit sis is defined as increased vigour, size, fruitfulness, speed of development, resistance to disease and insect-pests or to climatic rigours of any kind in F 1 generation.

The diamondback moth may have its origin in Europe (Hardy, ) but on the basis of the large complex and sexual forms of its parasitoids and host plants found in South Africa, Kfir () speculated that it originated in South Africa and then dispersed to similar arguments, Liu et al.

Inthe average U.S. corn yield was estimated at 9, kg per ha ( bushels per acre), and U.S. corn production was million Mg ( billion bushels). These increases were caused by better hybrids, improved cultural practices, and biotechnology.
Corn Corn hybrids were first commercially grown in the early s when the annual U.S. corn yields averaged 1, kg per ha ( bushels per acre), and corn production averaged 51 million Mg (2 Utilization of feterita-type and waxy endosperm sorghum grains in all-concentrate rations fed to yearling steers Performance of commercial dent corn hybrids in Indiana Jan J R Performance of commercial dent corn hybrids in Indiana Their comments, which appear only in the Conference on Heterosis Book of Abstracts (CIMMYT, ), were the incentive for this paper.

The average oil content of commercial corn hybrids planted in the corn belt has declined over the last 50 years from –% to %. 52 The apparent cause of this decline has been widespread use of one or two high yielding, low oil content corn inbreds.
At the same time, the iodine value of corn oil has increased from – to – Corn is the most important grain used as livestock feed in the world.
Corn starch is nearly % digestible and can be augmented by grain processing. Although corn is lower in protein than other feeds, corn is an important source of protein due to the volume fed. Corn also contains important minerals and vitamins for animal :// Corn has reached its present state of development through continual mutations, hybridizations, segregations, and selections by random, natural processes and conscious selection.
By this process, a number of types have developed which differ primarily in structure of the seed. Examples are popcorn, sweet corn, dent corn, flint corn, and flour :// Waxy corn or glutinous corn is a type of field corn characterized by its sticky texture when cooked as a result of larger amounts of corn was first described from a specimen from China in As this plant showed many peculiar traits, the American breeders long used it as a genetic marker to tag the existence of hidden genes in other maize breeding :// Ears from six corn hybrids harvested on the same date.
In the two early-season hybrids on the right, the milk line has receded to the kernel base and disappeared; in the two mid-season hybrids in the center, milk line is evident near the base; while in the two full-season hybrids on the left, milk line appears at or slightly below the kernel Performance of yearling dairy heifers and steers on sweet corn, popcorn, dent corn and high-sugar corn silages.

The maximum fresh ear yields ( a nd kg ha - 1, respectively) were obtained The measurement methods of most value to determine corn quality depend first and foremost on the use to be made of the corn. While corn may be used for wet milling, dry milling, dry-grind ethanol processing, snack food or alkaline processing, feeding, or seed production, each of these uses has specific measurement methods that help select optimal quality of corn for each :// The Monsanto Company (/ m ɒ n ˈ s æ n t oʊ /) was an American agrochemical and agricultural biotechnology corporation founded in Init was acquired by Bayer as part of its crop science division.
