BURAKOCHWASTY I POŚPIECHY NA PLANTACJACH BURAKA CUKROWEGO

Sugar beet is one of the more important crop in Poland. Occurrence of bolting plants as an effect of vernalization was previously known but such plants created seeds very rare. Sugar beet seed plants appeared in nineties of XX when seeds produced in Mediterranean Sea area were introduced to practice in Poland. They are a progeny of hybridization between breeding materials and beet wild species beet. The increase of seed plant number in field is a result of growers’ neglect. Monitoring in north west part of Poland shows that the situation in some fields is critical and number of weed beet is so high that it is almost impossible to sow sugar beet there.
