Evaluation of Agronomical and Quality Traits of Triticale Genotypes in Spring Planting under Arid Conditions of Gumushane.

Abstract

This study was conducted in spring planting, under arid conditions of Gumushane, Turkey in 2013 year. The trial was arranged according to the completely randomized block design with three replications. Some evaluated agronomical and quality traits such as plant height (58.3-71.4 cm), spike length (4.80-6.27 cm), test weight (73.077.7 kg hl-1), grain moisture (10.4-10.8 %), starch ratio (61.6-64.7 %) and hardness (101.3-110.9 unit) were statistically different; however, other traits like biomass (4.27-4.98 t ha-1), grain yield (1.30-1.64 t ha-1), grain number per spike (22.3-29.2 no), spike yield (1.60-1.82 g spike-1), thousand kernel weight (32.6-38.1 g), protein content (11.6-13.0 %), wet gluten content (28.1-30.5 %), zeleny sedim (35.7-47.3 ml) and alveographic energy (203.7-235.2 Joule) had non-significant variations. As a yield component, spike yield showed significant relationships with thousand kernel weight (r = 0.438*), protein content (r = -0.394*), and grain moisture (r = 0.423*) at probability of 0.05 while protein content presented sharp relations with starch ratio (r = -0.853**), wet gluten content (r = 0.884**), zeleny sedim (r = 0.971**), and energy (r = 0.714**) at P < 0.01. Especially, negative significant correlation between starch ratio and protein content has indicated that starch accumulation instead of the protein in grain can be decreased the protein ratio.
