Careful collection of seeds of the local populations of giants and elephants will be done by traditional and diligent growers of the area. From the genetic material that will be collected, two experimental fields of selection and observation will be installed in the area. Experimental fields will be isolated from other crops to avoid accidental crossbreeding. The improvement works will eventually create two new populations (varieties), which will have the characteristics of the old local populations of the area, improved in terms of the appearance of their seeds and improved in terms of their productivity.
