RESULTS OF STUDYING COLLECTION MATERIAL FOR OAT BREEDING

Abstract

Results are given from studies on genetic diversity of oat collection material from the VIR collection to further use it in the breeding process. Investigations were conducted at the Narym Breeding and Seed Production Department of the Siberian Research Institute of Agriculture and Peat in 2011-2013. Thirty five oat samples were analyzed. The investigation of samples showed that weather conditions, considerably varying across the years of studying, had a significant impact on the growth and development of oats. Under drought conditions, technological grain quality became worse, productivity and the height of the plants decreased, resistance to lodging increased. Under conditions of high moistening and heat deficiency, unevenly distributed over the growing season, against the background of poor natural fertility, yields and the height of oat plants decreased more than under hot and dry conditions against the background of mineral fertilizing, but processing qualities improved. There were selected the best samples of oats as to yielding capacity, large kernel, small chaff and great thousand-kernel weight.
