SEED PRODUCTION OF GRAIN-FODDER CROPS AT THE NARYM STATE BREEDING STATION: HISTORICAL REVIEW

Abstract

There are presented the historical material on original seed production of grain-fodder crops at the Narym State Breeding Station, Tomsk Region. The material was prepared according to archive documents, reports of researchers for 1938-2014. The barley seed production work started in 1938, oats in 1939. In the thirties-forties of the XX century, the key task of seed production was to produce high-yielding elite seeds of high varietal purity, good sowing qualities, free from pests and diseases, which passed systemic directional selection and training in primary seed production network. The work towards improving the productive qualities of elite seeds of oats and barley was done by means of itravarietal hybridization, strict grading of lines against a high agricultural background, and selection of the most high-producing offspring. Since 1956, seed production has changed over to the method of individual-nepotistic selection. As a result of experiments has been found that the NPK-compound application to oats produces a significant increase in productivity. With the separate application of nitrogen, phosphorus and potassium, the significant increase in yield was obtained only from nitrogen. Beginning with 1973 and up to now, seed production produce only seeds of oat varieties bred at Narym: Narymskiy 943, Taezhnik, Metis, Togurchanin, Mustang. As a result of the work done, the original high-quality stock seeds are produced annually.
