Durio zibethinus L.

Durio zibethinus L. is a large and tall trees probably grew in the jungle before they are domesticated and planted in the villages and orchards. The fruit has a strong and thick spiny husk and a strong smell. It is a common fruit in Southeast Asia, where it is called by the name durian. The durian plant has one or two fruiting seasons per year, when virtually all plants within a location bear fruits simultaneously. Luckily, fruiting seasons may vary in term of time of the year for different area. When the fruiting seasons do come, the fruits can contribute to substantial income for the village people and entrepreneurship-minded orchard owners.

The plant can be grown from seeds but more commonly grown from grafted plants. Grafting is done by grating buds from plants of known high quality variety or clones to a seedling of high disease-resistant stock. Plants grown from seedling are not consistent in quality and flavour. Besides, it takes 10-15 years to bear fruits. It was said that if one plants durian from seeds, one is planting it for one's grandchildren. However with the grafted plants, fruiting can happen between 5-7 years.

In the wild, the durian can have likable taste and non-likable taste. The one shown below is small in size, strong yellow colour of edible pulp and relatively softer spines on the husk. Although the fruit offers non-likable smell and taste, the genotype may provide good stock for breeding better and tastier durian varieties.

Durian is classified under the Order Malvales. However, there are differences in opinion whether the Genus Durio is classified under the family Malvaceae or the family Bombacaceae. The site here gives this classification scheme, in which the subfamily Durionoideae is placed in the family Sterculiaceae, and not family Bombacaceae nor family Malvaceae

For clarification opinion from the experts in field of Plant Systematics should be consulted.
