Brief Summary of Minutes of Annual Meeting

The committee met in Puerto Rico in February of 2005. This committee continues to use multiple nurseries across the US and in Puerto Rico to determine disease resistance. The effort has paid off in great measure this year. This work could not be done without the climate and environmental differences that exist among the states and territories participating on this committee. This year the committee released a Black Bean breeding line under the name of Condor. It is high yielding, is suitable for direct harvest, has improved levels of resistance to anthracnose and has excellent canning quality. Redcoat was released from the Soldier breeding line and is based on bush habit, full season maturity, improved levels of resistance to anthracnose and bean common mosaic virus. It has unique disease resistance and quality traits that had not been found in the Soldier class. Six new Great Northern lines were released. They are the first lines to have resistance to rust. They have four genes for rust resistance. Snap bean breeding lines are showing resistance to beet curly top virus. A red kidney line will be released that has BGYM resistance and heat tolerance. As can be seen from the minutes, a large amount of work continues in each of the areas of the project. This work will result in new breakthroughs in both dry bean and snap beans. The contribution by a number of states has led to the new lines with disease resistance and the work will continue to yield new avenues for beans. Without question this committee is contributing enormously to bean quality and will continue to benefit the world in getting a food commodity that is high in protein which is sorely needed in both developed and developing countries. As the Administrative Advisor, I commend the great work this multi state team is accomplishing. Their new project proposal will position them to make even greater strides in improved quality and disease resistance of dry beans and snap beans. The impact of the work of this committee spreads around the world.
