Theme Goal

• Undertake world-ranking plant biology and crop improvement research …

• To support small holder farmers, by expanding and diversifying the use of RTB crops as renewable sources of …

• high-value food, feed and industrial biomaterials (carbohydrate and fiber)

Science Challenges

• To stay at the cutting edge in the successful RTB crop production for food, feed and industrial applications, strong linkage between basic plant science with delivery of new tools and genes for next-generation plant breeding needs to by consolidated.

• To unravel novel metabolic processes in RTB crops that enable the creation of new market opportunities for small holder farmers with access to added value food, fiber and carbohydrate products (i.e., high pVA or waxy starch).

Breeding

• We need to establish ………

• The current rate of yield increase by RTB growers.

• How much of the gains are explain by plant breeding…

• The level of research investment required to double the genetic gain through improved:
