RESEARCH ON THE BEHAVIOR OF SOME WINTER BARLEY VARIETIES AND LINES IN PEDOCLIMATE CONDITIONS AT A.R.D.S. SECUIENI, DURING THE PERIOD 2019-2022

Abstract

The main purpose of this study was to establish the adaptability of 10 Romanian winter barley varieties and lines (creations of the National Agricultural Research Development Institute Fundulea) in the pedoclimatic conditions of Central of Moldova. On average, in the three years of testing, the yields obtained by the winter barley varieties and lines, varied from 5484 kg  ha^-1 at the DH-432-6 line to 7587 kg  ha^-1 at the F8-4-18 line. Compared to the yield recorded by the control variety, Dana (6221 kg  ha^-1), the Cardinal variety – 6838 kg  ha^-1 and the F8-4-18 line (7587 kg  ha^-1) obtained higher yields, these being statistically ensured and interpreted as significant respectively very significant. The varieties of barley studied (Univers, Andreea, Artemis, Gabriela) produced higher yields than the control, but had no statistical interpretation.
