GULMEZOGLU, N., O. ALPU and E. OZER, 2010. Comparative performance of triticale and wheat grains by using path analysis. Bulg. J. Agric. Sci., 16: 443-453
The objectives of this study were to compare released triticale cultivars in terms of grain yield, plant height, protein and spike characters with bread and durum wheat and to evaluate the usefulness of path coefficient analysis for interrelationships among characters determining grain yield in triticale, bread and durum wheat in two locations. It was found that grain yield of triticale was statistically significant higher than that of durum wheat; however, triticale and bread wheat nearly had the same yield. Path coefficient analysis revealed that grain yield of triticale depended on the effect of four yield components (plant height, grain number per spike and thousand grain weight was positive and protein was negative) whereas grain yield of bread and durum wheat was due mainly to plant height, length of spike, protein, in addition to these, spike weight for durum wheat. Even though the effect of spike weight was positive, plant height and protein had a negative effect on the grain yield of durum wheat.
