In addition to the EPD and accuracy shown in a chart, often the percent rank is also given. This shows what percentile the animal ranks for the given EPD. The higher the percentile, the better the EPD is for that characteristic. The better the EPDs for a given bull, the higher chance its progeny will have a given characteristic. [5]
The extensive use of artificial insemination in domestic animals has helped in increasing the selection intensity on male animals. This selection tool is usually used for characters that are sex-limited, expressed after death (meat characteristics) and usually with low heritability, for example, milk or egg production in females.
In statistical quality control, the individual/moving-range chart is a type of control chart used to monitor variables data from a business or industrial process for which it is impractical to use rational subgroups. [1] The chart is necessary in the following situations: [2]: 231
Harvest the corn when the husks are dry and brown. [7] Glass Gem is a fast maturing variety. Typically, it is ready to harvest in 110–120 days. [8] By using simple selection it is easy to breed this variety of corn for the colors and patterns wanted. Select kernels with the desired properties from as many ears as possible.
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.
The US is the world's largest producer of corn. [8] According to the United States Department of Agriculture (USDA), the average U.S. yield for corn was 177 bushels per acre, up 3.3 percent over 2020 and a record high, with 16 states posting state records in output, and Iowa reporting a record of 205 bushels of corn per acre.
Selection is thus an ongoing process where deviants are selected or removed from the selection program. The main purpose of selection is to better the quality and yield of forthcoming plantations. Different approaches can be followed in the selection process of asexual plants, such as mass selection and clone selection from clone blocks.
Field corn is a North American term for maize (Zea mays) grown for livestock fodder (silage and meal), ethanol, cereal, and processed food products.The principal field corn varieties are dent corn, flint corn, flour corn (also known as soft corn) which includes blue corn (Zea mays amylacea), [1] and waxy corn.
