Abstract:

 

Using eight barley cultivars field experiments were carried out in Eskişehir, from 1991 through 1994. Water consumption and dry mater yield of genotypes were studied. Also, the yields and yield components as well as their relationship with dry matter production in different growing periods were studied. There was no significant difference among  evapotranspiration of genotypes. The Water Use Efficiency (WUE) varied with year. Mean annual WUE of genotypes varied from 3.6 to 4.75 kg / da-1 mm-1 for biological yield, and from 1.08 to 1.45 kg / da-1 mm-1 for grain yield.  Total dry-matter production  throughout the growing season and grain yields of the genotypes varied from year to year. Positive correlations were found between early  growth and the total dry matter production at maturity in 1991-92 and 1992-93. In 1991-1992 growing season, number of kernels per spike was positively correlated with grain yield, while the number of spike per unit area was positively correlated with grain yield in 1992-1993 and 1993-1994.  Genotype-year interaction was not statistically significant for evapotranspiration and number of spikes per square meter, while it was significant for total yield, grain yield, heading date, number of kernels per spike and 1000 kernel weight.  In view of these findings, the effect of genotipic characters on yield varies depending on year. It seems that characters such as number of spikes per square meter, number of kernel per spike, heading date and early  growth and  dry matter production at tillering are effective on grain yield.
