Breeding wheat on high bread making quality

After several past wheat breeding programms on yield (result cv. Pitoma) and high bread making quality (cv. Divana), the curent programme is redirected towards sustainable agriculture, with special emphasis on: - increase of wheat resistance or tolerance to prevalent diseases, - lower input in agricultural practice (mineral fertilizers and pesticides), - increased yield with the quality similar to that of cv. Divana In the first cycle of the current programme, donors of desirable characters were searched in the world collection of wheat (Argentina, Germany, New Zealand, Romania, and USA). The two selected donors were crossed with cv. Divana and big segregating F2 generation were produced and exposed to selection on phenotype. F6 generation consists of about five thousand genotypes. Strong selection on desired characters (disease resistance and protein content) were continued, and as a result, in F10 generation only 46 healthy lines with protein level similar to the better parent Divana were selected and put in yield trials. Due to extreme drought in 2003, absence of diseases and a common high quality did not provide good chances for efficient selection, and yield test in microtrials should be continued next year. On the basis of the results we could expect new wheat lines with grain yield equal or higher than standard cv. Žitarka, and bread making quality characteristics nearly as good as that of cv. Divana.
