Observation on Growth and production of Durian Clones| Happy Study From Tip Top Durian

Reference of summary from a research study

The object of this article is to provide background information which may be required for any future detailed study on durian.

In July 19 69, during the wet season, the recommended durian clones were planted.

The known clones planted were D2, D7, D8, D lO, D24, D66, D84, D88, D96, and an unidentified clone designated as DR.

The growth shape of durian trees appeared to differ slightly among clones.           

Although in this study the characteristics of all clones were measured and pictorally recorded, it would be desirable to extend the research to incorporate a study of the genetic sources of the clones and a in-depth morphological study of their differences.

Moreover, some research also include a comparative study of the performance of the same clones in different environments.

A comparison of crown shape by the techniques outlined earlier in this paper may require further verification and possible modification for wider use.

A close look at the planting pattern of durian clones may suggest certain lines of investigation. For example, a large tract of D8, clustered in one area may induce self-incompatibly within the clone and a detailed study on the pollen viability is required.

Over and above these, the conspicious absence of arboreal life, so characteristic of a ‘dusun’ at flowering times, may be a limiting factor in the pollination of durian flowers. For example, bats which pollinate the flowers are virtually absent even at midnight. Bees, another group of efficient pollinators, are also absent as there are no alternative hosts during the durian off-seasons.

Under the natural ‘dusun’ ecosystem, weeding is not carried out except during the fruiting season when the base around each tree is cleared to facilitate easy collection of fruits.
