Stages of Plant Breeding
G.I. Taranuho Selection and seed production of crops.
Breeding work is always strictly consistent in nature. It starts with setting goals and objectives, developing a model of the future variety, and then proceeding to a phased collection of targeted, creating and evaluating the source material, testing the offspring of selected plants and selecting the best constant families, numbers and variety samples.
The selection scheme includes the following steps:
1. Planning of the breeding process includes setting goals and objectives, developing models of future varieties, drawing up research programs and plans for laying experiments.
2. The creation of the source material begins with the attraction of available samples of the world collection of VIR and other breeding scientific institutions, the collection of local varieties and populations, and the production of new plant forms by various methods.
3. Isolation of ancestral plants with the necessary phenotypes is carried out under ordinary conditions and on provocative backgrounds as a result of a thorough assessment of the studied objects by direct and indirect signs.
4. A comparative test of the offspring of selected plants is carried out by families in breeding nurseries (SP), numbers in control nurseries (KP), varietal samples in competitive (CSI), environmental (ESI) and production variety trials (PSI).
5. The State Variety Test (GSI) is the final stage of selection, with positive results of which the new variety is entered in the State Register of Varieties and receives a ticket to life.
6. The introduction of zoned varieties into production is carried out with the direct participation and under the copyright control of its creators through the system of seed production.
