STUDY ON THE YIELD AND PRODUCTIVITY ELEMENTS OF AN ASSORTMENT OF WINTER WHEAT CULTIVATED AT ARDS CARACAL
On the chernozem from Caracal, in the agricultural years 2018-2019 and 2019-2020, 9 wheat varieties of Romanian origin were tested, creations of NARDI Fundulea: Glosa, Miranda, Izvor, Otilia, Pitar, Pajura, Semnal, Ursita and Voinic. The following characteristics were determined: height, number of ears / sqm, thousand kernel weight, test weight and yield. On average, none of the wheat varieties tested was significantly superior to the control variety Glosa, in terms of yield, although in the second year of testing the varieties Miranda, Pajura, Ursita stood out with significant increases. The average yield was within the limits of 8520 kg / ha for the Izvor variety and 9429 kg / ha for the Ursita variety. The correlations between yield and height, on one hand, and yield and test weight, on the other hand, were not significant, although 29% and respectively, 19% of yield variability, were associated with the variability of correlated characters. Deviations from the sense of correlation were present for the varieties Ursita and Pajura which had both high yields and high test weight, the correlation being negative.
