Spirit Newsletter nº10 / October 2016

Dear Spirit Forum member,

Last month we launched 10 new documents in the resources section of the Spirit portal. Especially, the document Combining ability analysis of yield and late blight resistance of potato germplasm in Rwanda summarizes the results of a study conducted to estimate combining ability effects for yield and yield related traits and late blight resistance in potato. The study identified ten top families with high tuber yield and resistance to late blight for further evaluation and release.

Moreover, according to a recent study the potato seed gap in Uganda is estimated at Shs 19 billion. Researchers from the Makerere-based Economic Policy Research Centre (EPRC) have found that the shortage in potato seed supply has taken a toll on farmers, especially in the Kigezi sub-region. To cover the seed gap researchers point out the need of buidling capacity in seed multiplication, as it will increase not only the quality of seed produced but also generate potato varieties that can be processed for value addition.

New topics were added to our LinkedIn group this month. Check out and join at East Africa Potato Value Chain!

Next 21st-23rd November, Ghana’s Science and Technology Policy Research Institute (CSIR-STEPRI) will be hosting the CAAST-Net Plus Workshop for Early-career African Climate Academics in Accra (Ghana). It will include a two-day workshop followed by a half-day field trip. The workshop will provide targeted information and guidance for early-career African researchers with a professional interest in sustainable agriculture intensification. It will pursue a predominantly training/workshop style and structure, with opportunities for researchers to work alone and in small groups to develop their own ideas, proposal and strategies.

Kind regards,

The Spirit Project Coordination Group

An Online Potato Pedigree Database Resource
October 20 2016 by NEIKER

At the Laboratory of Plant Breeding of Wageningen University, a large amount of pedigree data on current and historic potato cultivars and progenitors has been collected over many years. The sources and reasons for collection of these data are discussed. To allow others to use this data set for their own purposes, we have created a Web-accessible interface that allows querying of these data, e.g., for the ancestry of a cultivar of interest. This Web interface was recently extended and improved to allow users to create reports and dynamically created pedigree-tree images. Availability of this resource_2 and the options provided by the new Web interface are presented.

Breeding potato for high yields: A review
October 30 2016 by University of Rwanda
This article overviewed important topics related to the importance of potatoes, potato taxonomy and its origin and domestication. It also provided participatory research approach in potato breeding, and farmers’ trait preferences in potato breeding in Rwanda. Moreover, it went over potato genetics, conventional potato breeding for high yield, and molecular breeding applied to potato breeding such as maker-assisted breeding (MAB). In addition, gene action, and combining ability of potato yield were reviewed. Integration of MAB into conventional potato breeding program is promising for further research for crop improvement. This review may serve as a general frame work and important background information for potato breeders.
Combining ability analysis of yield and late blight [Phytophthora infestans (Mont.) de Bary] resistance of potato germplasm in Rwanda
October 30 2016 by University of Rwanda

Designed crosses among complementary parents and combining ability analysis are essential to recombine traits of economic importance and to select novel genotypes. The objective of this study was to estimate combining ability effects for yield and yield related traits and late blight resistance in potato. Crosses were performed using a 10 × 10 half diallel mating design to generate 45 F1s. Only 28 families with sufficient individuals and eight parents were field evaluated in experiments laid out in a 6 × 6 lattice design with two replications across two sites (Kinigi and Nyamagabe) in Rwanda. Late blight resistance was estimated using the relative area under the disease progress curve (rAUDPC: 100 % max). Furthermore, data on total tuber yield, total tuber number, and average tuber weight were collected and subjected to combining ability analyses. Results showed that additive gene action and non-additive gene action were present affecting yield and late blight resistance in potato. Additive gene action was predominant over non-additive gene action for both traits. All the families selected for further evaluation showed improved levels of late blight resistance and high yields. The study identified ten top families with high tuber yield and resistance to late blight for further evaluation and release.

Agriculture Land Information System launched in Rwanda

October 30 2016

On Tuesday 11 October, 2016, the Ministry of Agriculture and Animal Resources (MINAGRI) in partnership with the United States Agency for International Development (USAID), announced the launch of the Agriculture Land Information System (ALIS), a platform that will enable anyone with internet access to quickly retrieve online information on public agricultural land available for private sector investment.

Kenyan potato processors initiate contract farming to cope with shortage of potatoes for processing

October 28 2016

Two Kenyan potato processing companies, Tropical Heat (a manufacturer of potato chips) and Sereni Fries (a manufacturer of peeled, cut and blanched potato for preparation of french fries), have a agreed to sign contracts with potato growers worth Sh 180 million (1.8 million USD) to deal with the shortage of potatoes for processing.

Tropical Heat and Sereni Fries will sign contracts with growers to supply 600 tonnes of potatoes every month, ending the perennial struggle of Kenyan potato farmers to find markets for their produce.

Potato seed gap in Uganda

October 28 2016

According to a new study Ugandan potato farmers are suffering from a shortage of quality varied potato seeds, with a potato seed gap estimated at Shs 19 billion.
 
Researchers from the Makerere-based Economic Policy Research Centre (EPRC) have found that the shortage in potato seed supply has taken a toll on farmers, especially in the Kigezi sub-region. To cover the seed gap researchers point out the need of buidling capacity in seed multiplication, as it will increase not only the quality of seed produced but also generate potato varieties that can be processed for value addition.
