INVESTIGATION ON THE YIELD AND GRAIN QUALITY OF COMMON WHEAT (T. aestivum L.) CULTIVARS GROWN UNDER THE AGROECOLOGICAL CONDITIONS OF CENTRAL BULGARIA

The field experiment was held in Slatina, Bulgaria during the period 2012 - 2015. The test was performed by using blocking with four repetitions; experimental field area - 15 m2 with sunflower predecessor. The varieties common wheat Enola, Kristal, Pirineo, Bononia and Kapo, were studied. The growing of plants was performed in compliance with the standard technology. The aim of the present research was to carry out a comparison study of the yield and quality of some common wheat cultivars grown in Central Bulgaria. The analysis of the results showed that the highest grain yield was obtained from Pirineo variety - 7700 kg/ha, followed by Enola - 7567 kg/ha and the lowest one - from Kapo variety 6550 kg/ha. Among the studied common wheat cultivars, the highest values of thousand kernel weight and the wet gluten content was reported for Pirineo (51,7 g and 33.3%) respectively) and the highest values of test weight were reported for Bononia (84,7 kg). The lowest value of the thousand kernel weight was recorded for Kapo variety (43,0 g); the lowest value of the test weight and the wet gluten content was reported for Kristal variety (78,7 kg and 26.1% respectively).
