Screening of breeding material of naked barley for breeding-valuable traits in the conditions of the Rostov region

Abstract

The Southern Federal District is one of the main grain-producing regions of the Russian Federation. The share of the Southern Federal District, in which the Rostov Region is located, accounts for 12-15% of the total Russian barley production. In solving the problem of a further increase in yield and an increase in the quality characteristics of grain, the priority belongs to the variety. As a result of a long-term study of the collection of naked barley, sources of valuable traits and properties were identified: high grain content of an ear: K-9010 (Turkey), Akka (Israel), Nuda Bianco (Italy), 1057-1923 (Czech Republic), Buck CDC (Canada), K-266 (Pakistan); the number of productive stems per unit area: Kitaki-nadaka (Japan), K-11182 (Japan), K-3772 (Dagestan), Golozerny (RF); early maturity: Omsk golozerny 1 (RF), Brunee (Ethiopia), NB-owa (Nepal), K-11182 (Japan), Golozerny (RF), K-3038 (Turkmenistan), K-3426 (Japan), K-19103 (India), K-26598 (Ethiopia), K-266 (Pakistan), Korona Laschego (Poland). Over the years of research on a complex of traits, a number of samples have been identified that combine a high potential of grain productivity with resistance to lodging, different duration of the growing season and plant height: K-26598 (Ethiopia), 84469/70 (Czech Republic), CDC Dawn (Canada), Holozerny (RF), 1057-1923 (Czech Republic), Omsk Holozerny 1 (RF), K-6099 (Afghanistan), Akka (Israel), Kitaki-hadaka (Japan).
