Sweet Potato Soup

This there are recipe from my grandmother, I don't know this from malaysia is from cina, its the name Tong Sui.

I like Tong Sui is mouth scrubber soup chinese beloved. There is many types on tap Sui. Some people cooks it by the way of a real simple. Sweet potato soup was very easy and makes it only require time 20 minutes.

Sweet potato basically eaten by poor people. I remember when my old fellow tells that during second world war, safe people because there are sweet potato because easy to in planting and growing.

But now shall no longer and this recipe need to be tried

Ingredients

• 3 pieces of sweet potato
• 1 brown sugar slab (for sweetness)
• 2 pandan leaves (for flavor)

Instructions

• Peel the skin off from the sweet potatoes and cut it into bit-sized chunks. I tie a knot on the pandan leaves so that I can easily remove it after the soup is cooked.
• Drop a piece of brown sugar slab into a pot of boiling water. I use three cups of water.
• I then just pour everything into the pot and boil it for 15 minutes. That's it -- sweet and simple.

Cassava Transformation and Friable Embryogenic Callus Development

At CIAT, genetic transformation of cassava is being used as a tool to support conventional breeding programs. The aim has so far focused on genes (such as those for pest resistance) not yet available in cassava germplasm, although the modification of metabolic pathways (like starch modification and b-carotene content) to improve cassava is also sought. Transgenic plants, and cell lines, containing genes for pest resistance, starch modification and herbicide tolerance, are now being produced. Molecular tests for gene expression, and preliminary bioassays to test efficacy of protection against cassava stemborer were carried out this year. We observed low levels of protection. However, more bioassays with younger larvae have to be done to confirm observations.

Transformation is now being achieved with friable embryogenic callus or FEC, and using a model, and farmer preferred cultivars. We have established FEC cell lines for four cultivars, two of which are for the North Coast, one for the inter-Andean valleys of Colombia, and a cultivar used as a model in transformation. We have therefore set up a system for scaling up cassava transformation at CIAT. Experiments are done 2-3 times a month, using Agrobacterium or biolistics, with at least four cultivars (TMS 60444, SM 1219-9, CM 2306-4, and M Col 2215).

Genetic Diversity Characterized

We extended our study of the genetic diversity of cassava landraces, using microsatellites, to assess the genetic diversity and differentiation of cassava landraces from five countries in South America, three in Central America, and four in Africa; and also to African cassava genotypes resistant to cassava mosaic disease (CMD). Analysis showed substantial genetic diversity in CMD resistance, with appropriate germplasm available for the genetic improvement of CMD resistance, as well as other traits, particularly yield. The study of genetic diversity in Tanzania, Nigeria, Uganda and Ghana revealed a broad and unique diversity of local land races that can serve as the basis for a breeding program.

The above results have been placed on the The Cassava Molecular Diversity Network (MOLCAS) Web Site and are available to the Cassava Community.
