HOMOGENEITY OF MAIN VARIETY SIGNS OF NEW SELECTION NUMBERS AND VARIETIES OF FLAX

Abstract

The results of evaluation are presented with method of ground control of the main varietal character-istics and selection numbers of flax new varieties, being on the state variety trial and included in the state register of breeding achievements and received from ASRL Falernskaya breeding station and Siberian SRIAandT. This estimate allows to avoid the production of non-fulfilled enough new breeding varieties. It is noted that all tested batches of seeds met the requirements of the state Commission for variety testing to varietal purity and uniformity of their main varietal characteristics. Of the 26 varieties and numbers pre-sented, 70% were tall, having a plant height of 95 or more centimeters. Good uniformity in plant height was characterized by a variety Alexandrite, Visit, Nadezhda, Tonus, Universal, Fakel, Caesar, Chenille, Azhur, Tomich 2, as well as numbers P-221, P-246, P-215, f-2001, f-2053 f-2100 f-2101 f-2102 f-2109 f-2110 and f-2111. Tested seed lots from new selection numbers and varieties of ASRL, and Chenille varie-ty and numbers f-2101 f-2102 f-2111 from Falenskoe breeding station, Tomich 2 variety from Siberian SRIAandT were characterized by high fiber content in the stems – 30% or more. High uniformity in fiber content of stems was observed in 25% of varieties and numbers tested: Nadezhda, Tonus Fakel, Caesar and numbers P-221 and P-215. The following varieties were included in the state register of breeding achievements and recommended for cultivation of new breeding varieties: Alexandrite, Sursky, Tonus, Caesar, Universal, Nadezhda and Visit, Chenille, Tomich. It is necessary to pass them in nurseries of primary seed for further successive breeding and introduction into production crops.
