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).

Peanut developers survey 'satellite imagery ground truth'
From : Seniorl Anzu Didinet Issue 7, 2007
Current research and development of the peanut crop or ground nut in Papua New Guinea is mainly undertaken by Ramu Sugar Limited, Trukai Farms and the National Agricultural Research Institute (NARI). This is through a collaborative project supported by the Australian Centre for International Agricultural Research (ACIAR) with a focus to improve peanut production. And a major objective is to develop and apply the satellite imagery technology to monitor spatial variability and improve productivity of peanut in Australia and to try and integrate the technology to monitor the peanut cropping systems in PNG.
Ground-Truthing and Global Positioning System (GPS) referencing of peanut crops is one activity under satellite imagery technology, which allows for ground surveys for interpretation of satellite images. This is done through site surveys with the use of geo-spatial technologies (satellite imagery and GPS machines).
From May 11-19, 2007 , Andrew Robson (Satellite Remote Sensing expert) from the Queensland Department of Primary Industry (QDPI), Australia, was in the Markham valley doing the ground truth exercise. With representatives from project partners, Mr Robson visited a number of peanut sites at Ramu Sugar, Trukai, NARI and some farmers' plots.
The images for the sites visited, which will be acquired in June-July, will be used to assess the promising peanut varieties recommended, the crop rotation effect on farmers' fields, commercial blocks, and the local peanut gardens.
The processed images have given a first hand glimpse of the best management practice of peanut farming. Data from pod and plant weights from the plots, which show the promising peanut varieties, can be correlated with the processed satellite images to support findings from peanut trials conducted.
Some peanut farmers have realised the importance of peanut rotation effect. This practice can be promoted and adopted by PNG farmers for better crop yields. Apart from the peanut crops being a leguminous plant (natural fertiliser), the rotation technique can also break the disease cycle in the crops. Peanut farmers interviewed during the field visits appreciated the initiative and indicated their interest to adopt some of the best management practices such as planting in rows and the crop rotation effect.
Ramu Sugar and NARI were introduced to a satellite image processing software - ENVI - and its application to peanut farming. The software will be used to assess the peanut crop health. These two organisations now have licensed copies of ENVI, which will process the satellite images provided by QDPI. Geographical Information Systems personnel from Ramu (Kelly Leo) and NARI (Mark Tinah) were briefly trained and are assigned on a full time basis to undermine the remote sensing work in order to achieve the ACIAR peanut project objectives.
Meanwhile, a training on the remote sensing exercise and its application in Australia and PNG is planned for June/July in Australia.
