| Abstract:
Experiments were conducted at Moghan Agri-Industry during 1995 and 1996 to evaluate xenia and metaxenia in hazelnut. In 1995, ‘Fertile de Coutard’, ‘Segorbe’ and ‘Ronde du Piedmont’ flowers were crossed with ‘Daviana’, ‘Negret’ and ‘Cosford’ pollen. The results of this study showed that nut and kernel weight and blank percentage could be affected by pollen sources. ‘Daviana’ pollen was the most compatible and ‘Negret’ pollen was not satisfactory for ‘Fertile de Coutard’, ‘Segorbe’ or ‘Ronde du Piémont’. In 1996, the reciprocal crosses were made. ‘Fertile de Coutard’ pollen significantly increased nut and kernel weight and decreased blank percentage. In another study, ‘Fertile de Coutard’, ‘Ronde du Piémont’ and ‘Segorbe’ flowers were pollinated with mixtures of ‘Daviana’ + ‘Negret’, ‘Negret’ + ‘Cosford’, and ‘Cosford’ + ‘Daviana’, as well as open-pollinated. The results of this study showed that the ‘Daviana’ + ‘Cosford’ pollen mixture significantly increased nut and kernel weight and reduced blank percentage. It was concluded that the pollen source affected nut and kernel weight, but had no effect on nut and kernel shape. | |
