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 ...
A doubled haploid (DH) is a genotype formed when haploid cells undergo chromosome doubling. Artificial production of doubled haploids is important in plant breeding.. Haploid cells are produced from pollen or egg cells or from other cells of the gametophyte, then by induced or spontaneous chromosome doubling, a doubled haploid cell is produced, which can be grown into a doubled haploid plant.
Awais Khan (born 1977) is a Pakistani-American plant geneticist and an associate professor at the College of Agriculture and Life Sciences, Cornell University. [1] [2]His research focuses on genetics of disease resistance in apples, [1] crop improvement, sustainable agriculture, and food security. [2]
Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant
The Max Planck Institute for Plant Breeding Research was founded in Müncheberg, Germany in 1928 as part of the Kaiser-Wilhelm-Gesellschaft. The founding director, Erwin Baur , initiated breeding programmes with fruits and berries, and basic research on Antirrhinum majus and the domestication of lupins .
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.

Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
The idea of using CCPs in plant breeding was published in 1956 [3] based on the barley composite cross devised by Harry Harlan and Mary Martini in 1929. [ 4 ] [ 3 ] Yield data for 4 different populations for 8–28 years were presented in the article and after 8–15 years of repeated breeding under natural selection , the populations out ...
