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.
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 ...
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]
Breeding also may introduce unique features, such as a new color or improvement to a plant’s form, says Mathey. Any new plant—houseplant, landscape annual, perennial, shrub, tree, or edible ...
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.
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.
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 ...
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
