During the past few days we have been celebrating what is called 'Chinese New Year' in Malaysia and Singapore, 'Spring Festival' in China and 'Tet' in Vietnam. In Malaysia and Singapore, lots of mandarin oranges are consumed during this festival. This year I have been struck by the fact that most of the mandarin oranges are seedless. If mandarin oranges can be made seedless, we may expect other citrus fruits to follow.
Of other tropical fruits, we can expect mangosteens to become seedless. Already we have come across the odd seedless mangosteen fruit. Somebody should find a way to convert this rare possibility to certainty. With durians, nangkas, chempedaks and chikus there are trees that produce fewer seeds per fruit as well as fruits with reduced seed size, but we do not know if complete seedlessness is possible. Does anybody know?
