Earliness, spike productivity and protein content in European winter wheat landraces and obsolete cultivars

Popis výsledku v původním jazyce

European winter wheat landraces and obsolete cultivars (121 accesssions in set I and 101 accessions in set II) with modern Czech cultivars were evaluated in three-year field trials. Number of grains in spikelets was highly correlated with spike productivity and HI (r=0.62 to 0.69) whereas relations between these two charactes and TGW were lower (R=0.20 to 0.51). Spike productivity characters, except of TGW, are in negative colleration with crude protein content in grain (r=-0.34 to -0.50). Regression analyses confirmed that main determinig character for the spike productivity is number of kernels in spikelets (about 40 % of variation) while effects of TGW are about half-size. Crude protein content was positively affected by plant height (15-30 % of variation), impact of grain weight per spike was lower (14-17 % of variation) and negative.
