Germplasm innovation in garden plants is the ultimate improvement and enhancement of seed quality through innovation in forest breeding or varieties. The goal of the work of garden plant breeding is high quality, beauty, diversity, and efficiency. The trait improvement of forest trees has changed a lot, from the traditional single trait gradually to the direction of multi-trait improvements such as disease and insect resistance and stress resistance.
Traditional forest tree breeding methods
For the breeding of flowers and plants in garden plant breeding more use the breeding method of seed selection. According to the purpose and kind of breeding, the selection method can be divided into two kinds of pure line breeding and mixed selection.
Hybrid breeding has been used as the main way to breed new plant varieties.
Usually, garden plants bred by the polyploid breeding method have characteristics such as thick and tall branches, bright flowers, thicker petals, longer flowering periods and convenient storage and transportation, etc. These excellent characteristics make the polyploid breeding method gradually get widely used in flower breeding.
Selection of explants and differentiation pathways
Lifeasible will consider the physiological characteristics and genetic factors of different tree species in the selection of explants, and at the same time, which explant is selected for vegetative regeneration is greatly related to its pathway of occurrence.
In the selection of tissue culture technology, the most suitable developmental method is usually chosen to ensure that the cultured tree species can fully inherit the excellent shape of the parent and adapt to the new environment after transplanting in a short period.
The tissues or organs selected for plant tissue culture must be those with complete genetic information, including stems, leaves, and germ of the parent plant. Although the genetic information in these tissues or organs is the same, their cultural effects can also be affected by external factors such as the cultural environment and nutrient content of the culture medium. Based on this biological characteristic, the formation process and structural characteristics of the tissues and organs of plants can be technically analyzed.
