The Relationships Among Phenological Stages, Grain Yield and Some Yield Components, of Two-Rowed Barley Cultivars Under Van Ecological Conditions

Abstract

This study was carried out in randomized block design with four replications in order to determine phenological periods, seed yield and some yield components of two-rowed barley varieties (Tarm-92, Ünver, Keser, Özdemir-05, Kalaycı-97, İnce-04 and Bolayır) in the 2017-2018 growing season under Van ecological conditions. In this study, the relationships among grain yield, other yield components and phenological periods were investigated by correlation and path analysis. In this study, vegetative period, grain filling time, germination ripening time, grain filling rate, fertile spike number per square meter, stalk length, spike length, grain number per spike, grain yield per spike, thousand grain weight and grain yield characteristics of the barley varieties were examined. According to the results of this study, it was concluded that grain yield was a function of vegetative period and grain filling period and it was determined that the effect of stem length on grain yield was positive and high. It has been concluded that vegetative term and grain load time is important selection criteria for growing wintery barley and due to the fact that it should be considered for breeding studies. © 2020, Centenary University.
