This is done through\u00a0genomic selection<\/a>\u00a0(GS), a technique that uses statistical models to predict how different cassava genotypes will perform in the field. Conventional cassava breeding methods can take 5 to10 years and require extensive trials. By using GS, breeders can more rapidly identify promising varieties and deploy them in field trials.\n\n\u201cCassava is the second most important food crop in Africa, which is the global leader in food production,\u201d stressed\u00a0Alfred Dixon<\/a>, Director of the Development and Delivery Office for IITA, who delivered the meeting\u2019s keynote address. With Africa\u2019s rapidly growing population and an estimated food import bill of $110 billion by 2025, he said it is critical to make the production of crops like cassava more efficient, modern, and competitive.\n\nUntil now, the project has primarily focused on laying groundwork. This includes capacity building, surveys to identify end-user preferences, stronger collaboration among partner institutions, training models, and mapping key areas of the cassava genome to better understand traits like resistance to viral diseases, pests, and enhanced nutritional quality. Phase I established CassavaBase (http:\/\/cassavabase.org<\/a>), an open-data breeding database where cassava breeders can upload and view genomic data from different experiments and partners.\n\nAnother clear success of Phase I was capacity building and training. \u201cWithout that important pipeline, long-term sustainable improvements in crop production will wither in the face of future challenges,\u201d said\u00a0Ronnie Coffman<\/a>, Cornell professor of plant breeding and genetics and Director of International Programs, who is the principal investigator on the multi-partner grant.\n\nIn Phase I, NextGen trained a total of nine PhD students (six at Cornell University and three at the West Africa Centre for Crop Improvement\u00a0(WACCI), University of Ghana) and nine master\u2019s students at Makerere University in Kampala, Uganda. NextGen has also streamlined African breeding programs and reinforced collaboration between partners in the US, South America, and Africa.\n\n\u201cThere is no doubt that science is critical for a transformational change of the cassava sector. And this is so because we now have more issues contending with the productivity of this root crop,\u201d said Olusegun Ayeni at the meeting\u2019s opening ceremony, speaking on behalf of the Hon. Chief Audu Ogbeh, Minister for Agriculture and Rural Development of Nigeria. \u201cFor us to tackle these challenges requires new breeding options that are quick and smart to address these emerging limitations.\u201d\n\nA \u201cmodel\u201d for future crop research projects<\/strong>\n\n\u201cNextGen is a model for multi-partner, global research projects where scientists are looking to improve crops that could be critical for food security for smallholder farmers in the 21st century,\u201d said Coffman. \u201cIn Phase II, there will be greater focus on developing varieties that can then be tested and released to farmers, which many hope will improve agriculture for smallholder farmers in Africa.\u201d\n\nRepresentatives from 10 institutional partners across six countries on three continents presented key findings and results from the first phase of the project at the meeting. These institutions include the\u00a0Boyce Thompson Institute<\/a>\u00a0(USA), Embrapa (Brazil), the International Center for Tropical Agriculture (CIAT<\/a>\/Colombia),\u00a0IITA<\/a>\u00a0(Nigeria), the National Crops Resources Research Institute (NaCRRI<\/a>\/Uganda), the National Root Crops Research Institute (NRCRI<\/a>\/Nigeria), the University of Hawaii (USA), the US Department of Agriculture-Agricultural Research Service, and the US Department of Energy Joint Genome Institute. Last year, NextGen Cassava expanded to include Tanzania, partnering with the Lake Zone Agricultural Research and Development Institute (LZARDI).\n\nNextGen Cassava is funded from 2012 to 2017, with a $25 million grant from the Bill & Melinda Gates Foundation and the Department of International Development in the UK through their UK Aid program. NextGen is up for a 5-year renewal in 2018.\u00a0 \u2013\u00a0contributed by Samantha Hautea, NextGen Cassava.<\/em>","protected":false},"excerpt":{"rendered":"
