An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Plant breeding started with sedentary agriculture and particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years. [9] Initially early farmers simply selected food plants with particular desirable characteristics, and employed these as progenitors for subsequent generations ...
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

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 ...
The International Treaty on Plant Genetic Resources for Food and Agriculture [2] (also known as ITPGRFA, International Seed Treaty or Plant Treaty [3]) is a comprehensive international agreement in harmony with the Convention on Biological Diversity, which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources for food ...
Vavilov's 1924 scheme suggested that plants were domesticated in China, Hindustan, Central Asia, Asia Minor, Mediterranean, Abyssinia, Central and South America A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties.

The insecticide kills insects that eat the plants but is harmless to people. [20] In these plants, the new genes are put into the plant before it is grown, so the genes are in every part of the plant, including its seeds. [21] The plant's offspring inherit the new genes, which has led to concern about the spread of new traits into wild plants. [22]
