Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA / RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself. [1 ...
The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its artificial manipulation to breed improved types. Only those breeding and selection methods are suitable for a crop which ...
Marker assisted selection can also be employed as a diagnostics tool to facilitate selection of progeny who possess the desired trait(s), greatly speeding up the breeding process. [56] This technique has proven particularly useful for the introgression of resistance genes into new backgrounds, as well as the efficient selection of many ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during plant breeding. [1] Objectives of gene pyramiding includes 1) enhancing trait performance by combining two or more complementary genes, 2) remedying deficits by introgressing genes from other sources, 3) increasing the durability.
