2011 ASHS Annual Conference

September 23 - 30, 2011

Most of the developed countries are in temperate climatic regions. Yield of crops per unit area in the temperate is much higher than that of the crops from the tropics. Crops from the temperate regions are also being improved for nutritional status and disease resistance. However, status of crops in the tropics is largely not well improved. Furthermore, there are more disease and pests in the tropics, which are simply favored by the tropical climatic conditions. What are the constraints and limiting factors for genetic improvements of tropical crops is the area of interest. This will be investigated in this colloquium by inviting well experienced crop scientists and plant breeders from the tropics. Focused discussion in breeding fruits and vegetables will help to synthesize the current issues and shape future breeding fruits and vegetables in the tropics.

Looming threat of climate change and its effect in the human life and agriculture are the burning issues at present.  Average temperature is already high in tropical region, what may be the potential effect of global warming further is the major concern at present. Adapting horticulture to future changing conditions is essential to meet the need of growing population and increasing demand for fruits, vegetables, and other horticultural products.  Compared to breeding efforts in the temperate regions, what is the status of breeding including germplasm enhancement, sharing germplasms and networking at global levels in the tropics. Breeding is a long-term activity, which takes about 10 years to develop a new variety of an annual plant species, this will be much longer in perennial species.  Modern breeding tools such as molecular genetics and genomics, and other biotechnological tools might be useful to shorten the duration breeding time. Discussion on these aspects may be helpful to integrate the genomic and biotechnological tools into conventional breeding of horticultural crops. In this colloquium, leading scientists in these field will update the status of selected crops grown in the tropics and introduce the need, significance, and benefit of fruits and vegetable breeding; discuss the current status and challenges of research in breeding for the tropics utilizing molecular biology, genomics, plant transformation, germplasm enhancement, and crop breeding for overall horticultural crop improvement. The discussion may stimulate the integrated breeding efforts and identify opportunities, strategies, and priorities for future progress in this area.  With its tropical climate year round, Waikoloa may be the perfect place to discuss this topic.
