Effet de l'irradiation par rayon gamma sur la variabilité de certains critères de qualité chez la clémentine Marisol [ EFFECT OF GAMMA RAY IRRADIATION ON THE VARIABILITY OF SOME QUALITY CRITERIA IN MARISOL CLEMENTINE ]

Citrus fruits have a great national social and economic importance. This article is part of an improvement and genetic diversification program of citrus, the aim of this study is to study the variability of selection criteria related to the quality of the fruit. 107 clones of clementine were applied by gamma irradiations on Marisol clementine buds. They were grafted onto macrophylla and planted with a spacing of 3x5 m2. The evaluation was focused on the organoleptic and pomological criteria. Statistical analysis showed significant differences between the control and irradiated clones of Clementine (Marisol) for all studied variables (sugar content, number of seeds per fruit, average fruit weight and percentage of juice and maturity index) except for the acidity of the fruit. Four irradiated clones of clementine were selected because of their good quality 30M57; 30M67; 50M51; 50M87; 50M91; 50M89 (seedless fruits, large caliber).
