Determination of Relationships Between Grain Yield and Some YieldComponents in Bread Wheat (Triticum aestivum L.)

This study was carried out to determine the direct and indirect effects of some yield components, such as plant height(PH), spike lenght (SL), spikelet number per spike (SNS), grain number per spike (GNS), grain weight per spike (GWS) and 1000 grains weight (1000GW), to grain yield using randomized complete block design with 3 replications in 22 advanced bread wheat line and 3 wheat varities (Flamura, Gönen, Pehlivan) at Application and Research Center, Uludag University Faculty of Agriculture, in years of 2009/10, 2010/11, 2011/12 and evaluated the relationship between agricultural traits by path analysis and correlation coefficient; was conluded that GNS and GWS can be used successfullyfor selection for grain yield at breeding wheat studies for Bursa conditions.
