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 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.
Cytoplasmic–genetic male sterility systems are widely exploited in crop plants for hybrid breeding, and for maintaining hybrid lines, due to the convenience of controlling sterility expression by manipulating the gene–cytoplasm combinations in any selected genotype. Incorporation of these systems for male sterility evades the need for ...
Plant breeding started with sedentary agriculture, particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years. Initially, early human farmers selected food plants with particular desirable characteristics and used these as a seed source for subsequent generations, resulting ...
[4] Since then, agriculture has been a staple for human civilizations and plant breeding has allowed more genetic diversity and a more diverse gene pool. [4] Germplasm resources allow for more genetic assets to be used and integrated for agricultural systems for plant breeding and bringing about new varieties. In addition, researchers are ...
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.
Pedro B. Escuro (2 August 1923 – 8 September 2000) was a Filipino scientist who specialized in genetics and plant breeding. [1] As a plant breeder, he made significant contributions to rice breeding.
A key event in the conservation of plant genetic resources was the establishment of the International Board for Plant Genetic Resources (IBPGR) (now Bioversity International) in 1974, whose mandate was to promote and assist in the worldwide effort to collect and conserve the plant germplasm needed for future research and production. IBPGR ...
