This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific.
The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR.
SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).

Nigeria:IITA begins preliminary on-farm trials of new yam growing technique
The International Institute of Tropical Agriculture in partnership with Nigerian farmers has begun preliminary trials of propagating yam through vine cuttings on farmers’ fields in Niger State, north central Nigeria.
The success of the trials and adoption of the new yam growing technique will substantially cut down the volume of yams used by farmers as seed yams. “The technology will definitely save farmers the cost and pains of acquiring seed yams,” says, Joshua Aliyu, a staff with Niger State Agricultural Development Project, who is also working on the trials. “It is actually a rebirth of yam cultivation in our community,” he adds.
The new yam growing technique has potential to eliminate the transmission of yam diseases (nematodes), which constitute considerable damage to yam tubers, according Dr. Hidehiko Kikuno, IITA’s Yam Physiologist and project leader.
On February 15, IITA and partners announced a breakthrough in the propagation of yams through vine cuttings via a research funded by the Japanese government (MOFA, MAFF), the Sasakawa Africa Association, Tokyo University of Agriculture and the International Cooperation Center for Agricultural Education, Nagoya University, Japan. Other partners in the research include the Tokyo University of Agriculture; National Root Crops Research Institute - Umudike, Nigeria; Crop Research Institute, Kumashi, Ghana and the Institute of Agricultural Research for Development, Cameroon.
The new yam growing technique makes use of vine cuttings planted in carbonized rice husk (CRH). After rooting and sprouting, the seedlings are transferred to the field or directly planted into nursery bed with CRH under shade.
Kikuno says the abundance and availability of rice husks—the growth medium – in rural communities makes the research relevant.
“This is because farmers can propagate the yam through vine cuttings by themselves,” he says.
In sub-Saharan Africa where the cost of planting materials (seed yams) account for about 50 per cent of the total cost, the new technology is seen as an option that will not only cut down the cost of production of yams but also make available more yam tubers for human consumption.
