Accelerated breeding of new and
improvement of existing cultivated plants
varieties
Proposed technology based on identification of tolerant genotypes
from the crops populations on marked traits allows fast on the seed
level select genotypes with one or a complex traits of interest in one
genotype. At that, each trait can be marked on enzymes or seed
proteins, correlating directly or indirectly with traits displayed.
Advantages of this technique of increase of plants tolerance to
unfavorable factors and varieties improvement are obvious. It is
elimination of random factor in the first instance. Besides, working with
seeds, as the selection process is conducted on the seeds level, it is
possible to work the year around, propagating plants in greenhouses in
winter season. Besides this technique is not time-consuming what is of
no small importance while improvement of existing or breeding of new
crops varieties, and doesn’t require expensive equipment. This
approach is applicable for all crops.
