Evaluation of Some Advanced Bread Wheat (Triticum aestivum L.) Lines for Agronomic Traits Under Kırklareli and Tekirdağ Conditions

Abstract

This study was carried out to determine grain yield and yield components of five bread wheat genotypes and 20 advanced lines at Kırklareli and Tekirdağ locations in 2017-2018 cropping year. The experiments were arranged in a randomized complete block design with four replications. In the study, grain yield (GY), plant height (PH), spike length (SL), number of spikelets/spike (SS), number of grains/spike (KS), grain weight/spike (KWS), test weight (TW) and thousand kernel weight (TKW) were investigated. Bread wheat genotypes were found statistically significant for all investigated traits according to the data obtained from two locations. According to the results of two locations the investigated traits such as GY ranked from 423.8 to 572.5 kg da-1, PH 85.3 to 116.2 cm, SL 8.8 to 12.2 cm, SS 16.5 to 21.6, KS 39.4 to 65.6, KWS 1.30 to 2.91 g, TW 65.9 to 75.6 and TKW 32.6 to 44.7 g. Relationship between GY and SS, KS and KWS were found positive and significant. In addition, relationship between PH and SL (r=0.39*), SS and KS (r=0.39*), SS and KWS (r=0.42*), TW and KS (r=0.42), TW and KWS (r=0.44*), KS and KWS (r=0.64**) were significant and positive. The highest grain yield was obtained from SME9 bread wheat advanced line at both Kırklareli and Tekirdağ, which was concluded as promising.
