Many tropical fruit trees, including tomatoes, mango, avocado and orange, perform better when farmers merge good fruiting characteristics with resistance to disease. To accomplish this, a single stem is placed on to a root stock tree. The stem eventually merges with the root stock to form the main trunk of the tree and from then on that tree bears fruit similar to the plant the graft was taken from.
The grafting technology, say scientists at National Crops Resources Research Institute (NaCCRI), has been embraced b... Read more

Most years at Johnny’s we trial roughly 300 varieties of tomatoes in the field, 50 in the hoophouse, and 10 to 15 different rootstocks for grafted tomatoes. It is a daunting task to evaluate 400 varieties every year and figure out which ones make se... Read more
