The importance of the yield components of the spring durum wheat varieties from Russia and Kazakhstan
Published 2020-10-01“…Field trials were carried out for three years (2015, 2016, 2018); the accounting area of the plots was 10.0 m2, with threefold repetition, with random plot placement; the sheaves for laboratory analysis were taken from each repetition (sampling area of 0.63 m2). Using the methods of correlation and path analysis, there has been established a significant correlation between variation of yield and such traits as economic coefficient (К.хозР), nature weight (H), 1000 grain weight (M1000), sterility of heads in the cenosis (Ст), number of grains per spikelet (ЧЗКК) and number of days before tillering (КДК).…”
