Variability of grain mass per spike in cultivars of triticale (xTriticosecale Wittm.)

Abstract

Triticale is a cereal species created by crossing the wheat and rye species. It is characterized by good quality and high yielding capacity which is specific for wheat and high tolerance to abiotic and biotic stress factors which is specific for rye. The high yield potential of triticale is determined by genetics and influenced by environmental factors. The aim of the paper is to present the results obtained at different triticale varieties under different climatic conditions regarding the grain mass spike-1. Five triticale (xTriticosecale Wittm.) cultivars (KG 20, Bolero, Rtanj, Odisej and Bogo) were investigated in field experiment which was conducted as a randomised block design in five replications on 5m2 size of unit plot, during three years period (2010-2013). In full stage of maturity 100 plants (20 plants per replication) were used for analysis of grain mass spike-1. Obtained results for grain mass spike-1 showed significant differences among studied triticale cultivars, years of experiment and interaction genotype/year. The average value of grain mass spike-1 for all three years and all five tested cultivar of triticale was 2.28g. The cultivar Bolero had the lowest average value (2.15g) and Odisej the highest value (2.52g) of grain mass spike-1 in average for three years period.
