| Summary: | Durian is a fruit under family Bombacaceae carrying the genus Durio has long
been known as king of fruit and is locally highly in demand when it comes to
seasonal fruits. Musang King (D197) variety is receiving a lot of attention due
to its high-quality taste of arils. As the interest of growers increase for Musang
King variety and to optimise its fruit production, growers start to plant durian in
monovariety fashion instead as recommended conventionally to plant more
than one variety in a planting area. Thus, this study aim is to elucidate the
pollination compatibility status of Durio zibethinus variety D197 (Musang King)
with regard of high fruit sets. Musang King trees used in this study were
located at durian orchards in Lembah Klau, Raub, Pahang owned by Lembah
Temir Resort. The experiment was carried out by pollinating flower of Musang
King as maternal with Musang King pollen of the same tree (PST), with
Musang King pollen of different tree (PDT), with pollen of D24 (xenogamy),
autonomous autogamy and in comparison, with openly pollinated acted as
control. Fruit sets of each treatment were recorded at 7th, 14th, 21st, 28th days
after anthesis or pollination and at harvest. Musang King durian flowers
showed herkogamy condition as the stamen tend to curve outward away from
the stigma during anthesis and throughout the flower development there is
difference of height between stigma and anther. Pollination study showed
crossing of Musang King with D24 variety produce significant higher fruit set
which was 16.28% at harvest while other treatments had 0% of fruits set at
harvest except for control or open pollination which fruits set recorded were
0.87%. Fruits set were significantly higher when Musang King flowers were
cross pollinated with D24 pollens (Xenogamy) compared to when selfpollinated
and open pollination. This indicated that Musang King is suitable to
be planted in polyvarieties instead of monovariety. |
