Genetic Plants:
Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. He observed that organisms (most famously pea plants) inherit traits by way of discrete “units of inheritance”. This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

What does a plant geneticist do?
Plant geneticists conduct research to understand, improve or create new varieties of plants or crops. Looking at a plant’s DNA, they can examine ways to improve shape, size, production level, pesticide and disease tolerance.
What are plant genetic factors?
The genetic factor is also called internal factor because the basis of plant expression (the gene) is located within the cell.Both plant growth factors interact in various ways. The genetic factor determines the character of a plant, but the extent to which this is expressed is influenced by the environment.
Plant Breeding and Genetics is a paper in the series on The Need for Agricultural Innovation to Sustainably Feed the World by 2050. Humans depend on plants for food, feed, fiber, and fuel—as well as less tangible aspects of life such as aesthetics and environmental stability. This paper is the first in a series that connects science and technology to agriculture, and it focuses on the critical importance of innovation in plant breeding to meet the challenge of providing food and nutritional security to humankind. Key areas covered include (1) the science of plant breeding and genetics; (2) the need for encouraging the next generation of scientists; (3) the current role of government policy and regulations; and (4) the need for cooperation and collaboration at all levels, including the public-private nexus. (Key Words: genetic technologies, genetic variation, phenotyping, hybridization, molecular biology, regulatory oversight, genomics, haploidy, cultivar).
