An Assessment on Grain Yield vs. Some Agronomic Characteristics in Bread Wheat (Triticum aestivum L.)
Öz
This study was carried out to determine grain yield, some agricultural and physiological characteristics of the some bread wheat varieties in 2009-2010 and 2010-2011 growing seasons in Edirne. Experiment was set up with 22 cultivars employing completely randomized blocks design with four replications. The characteritics such as grain yield, flag leaf area, canopy temperature, chlorophyll content of flag leaf, water content and dry matter of flag leaf, plant height, days to heading and maturating were scored.
Except grain yield all other characteristics were statistically significant. The two year average grain yield of all varieties was 721.8 kg/da. The highest grain yield (762.3 kg/da) was obtained from Trakya BVD7 . Tina variety gave the widest flag leaf area (32.96 cm2), while the lowest leaf area was measured in Kate A-1 variety with 18.54 cm2. Measurements of canopy temperature and chlorophyll content in flag leaf were performed at heading stage. Canopy temperature varied between 22.66 oC and 25.75 oC, the highest canopy temperature was measured for Tina and, the lowest was for Milena cultivar. The highest and lowest chlorophyll contents (53.41 and 46.89) were measured in Tekirdağ and Golia cultivars respectively. Bereket and Tekirdağ varieties gave the highest leaf water content and dry matter values, respectively. Although canopy temperature positively correlated with flag leaf area, it turned out to be negative with plant height (r=-0,459) and leaf water content r=-0,355). Coeffiicinet of correlation between plant height vs.chlorophyll content and leaf water content were positive but insignificant. Trakya BVD7, and Nina were prominent genotypes with their highest yielding capacities based on the result of the study. Relationship between grain yield versus physiological traits should be further carried out under drought conditions.
