D141 Hybrid T.No.30 (D101 x D2)

Overview

D141 is not a chance seedling found in a kampung orchard. It is the product of a deliberate scientific cross -- a hybrid created by pollinating D101 (Bangkok Tree 16) with D2 (Data Nina) as part of a systematic breeding program conducted by the Malaysian Department of Agriculture (Jabatan Pertanian). Registered in 1981 from Selangor, it carries the trial designation "T.No.30," meaning it was the thirtieth selection in the DOA's hybridization trial series.

Where most registered clones were discovered -- identified by farmers or field officers as exceptional trees on private land -- D141 was engineered. Its parents were chosen, the cross was performed under controlled conditions, and the resulting offspring was evaluated and formally registered.

The DOA description records D141 as a medium-large fruit with a wide elliptic shape, brown thin shell, thick flesh, slightly dry texture, and yellow coloring. These traits reflect contributions from both parents: D101 is known for large elliptic fruit with sweet, dry, yellow flesh, while D2 brings thin shell walls and thick flesh from its Melaka heritage. The "slightly dry" texture is inherited from the Thai-lineage D101 side, distinguishing D141 from the smoother, creamier profile that D2 alone would suggest.

Origin & History

D141 emerged from the DOA's research station in Selangor -- almost certainly the main facility in Serdang, the department's hub for durian germplasm collection and breeding since the registry's early decades. The hybridization program was methodical: the DOA did not cross varieties at random.

D101 (Bangkok Tree 16), registered in 1970, was a Thai-origin cultivar from the Serdang germplasm collection, valued for its large fruit, sweetness, and dry texture. D2 (Data Nina), registered in 1934 from Melaka, is one of the two oldest entries in the national registry, known for thin shell, thick flesh, and complex bittersweet flavor. By crossing these two lines, the DOA was combining the size and sweetness of Thai genetics with the flesh quality of one of Malaysia's most established heritage cultivars.

D141 was not alone. The DOA registered at least four hybrids from the same trial series in 1981, all from Selangor:

• D141 Hybrid T.No.30 (D101 x D2) -- the subject of this profile.
• D142 Hybrid T.No.34 (D66 x D2) -- medium-large, elliptic, thick brown shell, large thorns, moderately thick smooth yellow flesh.
• D143 Hybrid T.No.57 (D2 x D7) -- medium-large, elliptic, brown shell, large thorns, thick slightly dry bright yellow flesh.
• D144 Hybrid 7 (D24 x D2) -- large, ovate, brown shell, yellow-orange flesh with a creamy sweet taste.

The pattern is striking: D2 (Data Nina) appears as a parent in all four crosses. The DOA clearly valued Data Nina as breeding stock -- its established genetic lineage, thin shell, and distinctive flesh quality made it an ideal foundation for new combinations. The other parents (D101, D66, D7, D24) represent a cross-section of the available germplasm, from Thai-origin cultivars to established Malaysian varieties.

This 1981 batch predates the better-known MARDI hybrid program that produced D188 (MDUR78) and D189 (MDUR79) in 1991, showing that institutional durian breeding in Malaysia was already underway a full decade earlier.

Characteristics

Size: Medium-large, consistent with a cross between the large-fruited D101 and medium-large D2.

Shape: Wide elliptic. The "wide" qualifier indicates a broader fruit than a standard elliptic form. The elliptic shape likely derives from D101, while the wider dimension may reflect D2's influence.

Shell: Brown and thin. The thin shell is a trait shared with D2, which is also recorded as thin-shelled. Among its sibling hybrids, D141 is the only one explicitly described as thin-shelled -- D142 is recorded as thick-shelled -- suggesting the D101 x D2 combination passed on Data Nina's thin shell trait where other crosses did not.

Flesh: Thick and yellow, with a slightly dry texture. The "slightly dry" descriptor places D141 between D101's fully dry texture and D2's smoother quality -- a moderated version of the Thai-lineage dryness. This slightly dry character also appears in D143 (D2 x D7), suggesting it may be a recurring outcome when D2 is crossed with certain partners. The yellow coloring aligns with D101 rather than D2's orange-yellow tones.

The DOA record does not include information about flavor, aroma, seed size, or thorn characteristics.

Availability

D141 is unavailable in the commercial market. It was registered as an experimental hybrid, not a variety recommended for commercial planting. No nurseries advertise D141 saplings, no durian stalls list it, and no tasting reviews have been identified.

The hybrid likely exists only within the DOA's germplasm collections, possibly at the Serdang research station. Whether the original trial trees survive after more than four decades is uncertain.

D141 and its siblings (D142-D144) represent institutional breeding work that never reached the commercial stage -- the DOA registered the crosses for documentation and germplasm conservation, but did not promote them to the nursery trade. For researchers and enthusiasts, the series is nonetheless valuable as evidence of Malaysia's early structured approach to durian improvement: deliberate crossing of Thai-origin and Malaysian-heritage genetics, systematic trial numbering, and formal registration of results, a full decade before the MARDI hybrids that would later receive wider attention.
