An evaluative comparison of the Wase Satsuma group with four subgroups of what are possibly mutant clones of the Wase group was carried out. All the clones were grafted onto Citrus aurantium L. rootstock. For the comparative study of the clones, characteristics such as vigour, yield, fruit quality and other morphological characteristics were evaluated. The results showed that the four mutant clones have significant morphological differences from the Wase group. Major characteristics such as yield level, fruit morphology and juice quality were found to be better over 3 consecutive years in the mutant clones. Clone A gave a greater yield and larger fruit size compared to the Wase group. Clones B and C showed improved juice quality characteristics such as low acidity, higher soluble solids and vitamin C content compared to the Wase group; these clones also have a thinner peel with the result that the ratio of flesh: peel is greater than that of the Wase group and the other clones. Clone D is characterized by late ripening, 15 days after the Wase group and the other 3 clones studied, while the other characteristics are typical of the Wase group. |
