With the development of modern science, scientists have collected most of the useful genes of plants in the world and stored them in a “warehouse” called “gene pool”,
commonly known as “seed bank” [14]. It is used to preserve the germplasm resources,
and there are advanced heat-preservation and moisture-insulation structures and airconditioning instruments in the storehouse. It maintains a low temperature and dry
environment all the year round, slows down the metabolism of seeds, and prolongs
the life span of seeds, so that the seeds in a few or even the last 100 years still do
not lose the original heredity and germination ability. In nature, all organisms show
their own genetic phenomenon, which is the guarantee of life continuation and racial
reproduction of germplasm resources. Farming proverb says that “as a man sows, so
he shall reap” which is a vivid description of genetic phenomena. The reproduction
of beans and melons is determined by genetic material.
The evaluation of industrial oil plant germplasm resources is to describe and
compare the characteristics of various oil plant germplasm samples collected for
industrial purposes under suitable environment and specific conditions, and to comprehensively evaluate the status of various oil plant germplasm resources in industrial
oil plant and their potential for development and utilization. The ideal evaluation of
germplasm resources includes not only the description of phenotypic traits, but also
the description of genes that control phenotypic traits, as well as the description
of phenotypic traits, the interaction between genetic traits and environment. The
evaluation of industrial oil plant germplasm resources is the focus of research and
development of industrial oil plant germplasm resources, and it is the basis of the protection, utilization and deep development of industrial oil plant germplasm resources,
and the comprehensive and accurate evaluation of industrial oil plant resources. The
analysis of its position and the potential of its development and utilization is of great
significance to carry out directional breeding, expand the genetic basis, improve the
breeding level, cultivate the resources with characteristics, and realize the sustainable
and multilevel development and utilization of resources.
1.1.2.1 Evaluation of Plant Germplasm Resources for Industrial Oil
Industrial oil plants play an important role in industrial plant resources, which are
rich in resources and varied in variety. According to the traditional methods, they
can be divided into herbaceous industrial oil plants, woody industrial oil plants and
aquatic industrial oil plants [15]. According to the current distribution, domestication
degree, utilization status and source of species, industrial oil plants can be divided
into natural wild industrial oil plants and wild cultivated industrial oil plants. There
are four categories of cultivated industrial oil plants and foreign oil plant resources.
According to the oil content of plant oil, it can be divided into two categories: high oil
content oil (rape seed, cotton seed, peanut, sesame with oil content more than 30%)
and low oil content oil (soybean, rice bran and other oil content that is about 20%).
At present, industrial oil is mainly used as an alternative to petroleum production
energy, materials and oil-based chemical products.
