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.
Ernest Brown Babcock (1877–1954), US plant geneticist, pioneered genetic analysis of genus Crepis; Édouard-Gérard Balbiani (1823–1899), French embryologist who found chromosome puffs now called Balbiani rings; David Baltimore (born 1938), US biologist, Nobel Prize for the discovery of reverse transcriptase
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 breeding is the science of changing the traits of plants in order to produce desired characteristics. [1] It is used to improve the quality of plant products for use by humans and animals. [2] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.

A view of an infected pepper . Colletotrichum capsici has a broad host range but prefers peppers, yams and eggplants. On chili peppers, Capsicum annuum L., C. capsici infect the stem, fruit, and leaves of the plant, causing anthracnose, die-back and ripe fruit rot.
O. sativa uses the plant hormones abscisic acid and salicylic acid to regulate immune responses. Salicylic acid broadly stimulates, and abscisic acid suppresses, immunity to M. grisea; success depends on the balance between their levels. [25] [26] O. sativa has a large number of insect resistance genes specifically for the brown planthopper. [27]
