METHOD TO REDUCE TIME FOR REPRODUCTION OF SELECTION SEEDS TO START OF STATE TESTS, WHICH RESULTS IN INCREASING CROP CAPACITY OF SELECTION SEEDS MANY TIMES, REDUCED TIME OF CROPS RIPENING AND IMPROVED SEED GROWING Russian patent published in 2011 - IPC A01F25/00 

FIELD: agriculture.

SUBSTANCE: reproduction of selection seeds before start of state testing is carried out for several agricultural years. To reduce time of selection seeds reproduction, a tight chamber is used, in which the optimal controlled gas medium (N₂+O2_opt) is formed. Two main actions are carried out in each agricultural year: storage, starting from the first best selection sample or seeds from it, and sowing-planting of stored selection material in accordance with the procedure of the Russian Academy of Agricultural Sciences. The selection material produced in a crop from the first batch undergoes certain testing and is again put for storage (the second agricultural year) into a chamber, where optimal controlled gas medium is provided, and the selection material is stored for the second year. Whenever the sowing time comes, seeds are sown on a large site according to the procedure of the Russian Academy of Agricultural Sciences. Such agricultural years are repeated until required quantity of selection seeds is received, at the same time each year they monitor increasing volume of seeds in order to select an appropriate volume of the chamber.

EFFECT: provision of durable storage of selection seeds with the purpose of their further reproduction.
