Disease resistance
  • Selected at IITA for resistance to cassava mosaic disease (CMD), a defining objective of the TMS improved-variety program.

TMS 30572 is an improved cassava variety developed by the International Institute of Tropical Agriculture (IITA). It belongs to the "TMS" (Tropical Manihot Selection) series, IITA-bred materials produced through hybridization and clonal selection, and it became one of the most widely disseminated improved cassava varieties in Nigeria and across West Africa.

A central objective of the TMS program was resistance to cassava mosaic disease (CMD), the most damaging viral disease of cassava in Africa. TMS 30572 was selected within that program and, as an improved variety, is propagated clonally from stem cuttings like other cassava.

Origin and breeding

TMS 30572 was developed within IITA’s cassava breeding program in Nigeria. The TMS series combined hybridization and clonal selection, drawing on sources of disease resistance to build improved varieties suited to African production conditions. TMS 30572 is one of the widely known outputs of that effort.

As an improved variety it is maintained and multiplied clonally, through stem cuttings taken from healthy plants, so that the released material retains its selected characteristics.

Disease-resistance context

Cassava mosaic disease (CMD) is the most economically damaging viral disease of cassava in Africa, transmitted by whiteflies and through infected cuttings. Breeding CMD-resistant varieties was the defining goal of IITA’s TMS program, and TMS 30572 was selected for this resistance.

Use and processing

TMS 30572 is grown for roots processed into staple products such as gari, fufu, and flour, as well as for fresh use and industrial starch, and its planting stems are retained as propagation material for the next cycle. As with cassava generally, processing and end use depend on the variety’s cyanogenic potential and local practice, which are not detailed at the variety level here.

Scope & limitations

Geographic scope: Bred at IITA (Nigeria) and disseminated across Nigeria and West Africa. Performance is specific to tropical African production conditions.

Climate context: Improved cassava variety for warm, humid-to-subhumid tropical West Africa; frost-intolerant.

  • CMD resistance is a provenanced, source-backed claim, not a guarantee of immunity; it can be affected by virus strains, disease pressure, and location, and may erode over time.
  • The specific national variety-release record in Nigeria is administered by national authorities and is not linked here; this record names IITA as the breeding institution.
  • No release year or yield figures are asserted, as they are not independently verified in this record.
  • Cyanogenic potential and required processing steps are variety- and practice-specific and are not detailed here.
