Abstract: Climate is an important factor for agricultural production. The climatic change has potentially threatened the present sustainability in agriculture sector. Very high losses of agricultural production –including in production of food crops, are expected to occur, especially in Africa and South Asia. The impacts of climate change are already visible. A network of 15 centres of Indian Council for Agriculture Research (ICAR) has reported that apple production is declining in Himachal Pradesh due to inadequate chilling. The climatic change has potentially threatened the present sustainability and motivated for research in this direction during the last decade. As Uttrakhand hills are rich of diversity for fruit and various crops so this diversity can be utilised for designing the crop for climate change. Our paper includes the model by which the crop can be designed for future changes which include three main approaches: Pre-breeding, Predicted climate change simulation and pressurized invitro- selection. Pre-breeding is the art and science of identifying desired traits in otherwise unprepossessing and unpromising plants, often wild, and starting to incorporate them into modern varieties in the context of emerging stresses due to climate change. Pre-breeding is a vital step in the link between conservation and use of plant genetic resources. Thus it is first step for genetic enhancement of crop. The second step of designing the crop is possible climate change and third is invitro selection. This selection allows well suited genotypes to select for altered environment.
