Various agroecological factors modifying the yielding ability of seeds have been investigated in a spring variety of Triticum durum in order to determine which of them has decisive importance. To exclude the influence of soil conditions the modification of the yielding ability of wheat seeds was performed by their reproduction in vegetation dishes on sandy substratum. Maternal plants were grown under 6 variants of mineral nutrition and 3 variants of soil moisture regimes. The modified seeds were tested for their yielding ability in the folowing year. It was found that the main modifier was the moisture regim of the substratum on which the seeds were reproduced. Enhanced yielding ability was realized through the increase of the number of seeds per spikelet. Other yield components, such as stem length, spike length and tillering capacity were also studied. Our data show that they remain unchanged in plants grown from seeds with high yielding ability as well as in ordinary plants.
