Abstract EN
The present investigation was conducted during 2010/2011 and 2011/2012 growing seasons at Karahta station for field crops research, General Commission for Scientific Agricultural Researches (G.C.S.A.R.), Syria.
Forty five hybrids F1 produced using a half diallel cross among ten bread wheat (Triticum aestivum L.) genotypes, in 2010/2011 season, were evaluated during 2011/2012 season in order to study som of the genetic parameters for grain yield per plant, its components, some morphophysiological and quality traits to determine the basic criteria for selection.
The obtained results indicated that estimates of additive gene action variance (VA) were significant for number of days to heading, flag leaf area, plant height, number of spikelets per spike, thousand kernel weight and protein content traits.
Also, dominance gene action variances (VD) were significant for most characteristics except flag leaf area, number of spikelets per spike and protein content.
High narrow sense heritability (h2 ) estimates were detected for plant height (0.75), protein content (0.74), and thousand kernel weight (0.61).
Grain yield showed positive significant correlation with biological yield per plant (r= 0.50**), less positive significant correlation with number of spikes per plant (r= 0.41**), and negative significant correlation with number of days to heading (r= -0.27**) and protein content (r= -0.23**).
Path coefficient analysis showed that each of biological yield per plant, number of spikes per plant and thousand kernel weight had high positive direct effects on grain yield.
This means grain yield improvement can be achieved by increasing yield components aforementioned.
