| Abstract:
Hazelnut (Corylus avellana L.) main cultivars form a large number of crown suckers. Also cv Tonda gentile delle Langhe (TGL) grown in Piemonte region (Italy) shows this negative habit. Through crossing with non-suckering species of Corylus, plants have been obtained with the same character, which can be used as rootstocks. In our Institute we tried to create selections of TGL without suckers by means of induced mutagenesis. 500 plants of this cultivar were treated with Morphological and vegetative characters of these mutants are described. | |

rays at 8 kR, with the aim to hit the crown zone where adventitious buds are formed.
Suckers arising from these buds were isolated and transplanted in number of 1150.Six of them did not form any suckers in five years of observations.
