| Abstract: | A comparison was made of two breeding procedures for recurrently selecting potato,Solanum tuberosum L., for resistance to infestation by potato leafhopper,Empoasca fabae (Harris). On the basis of selection advance per year, the more efficient procedure involved randomly intermating a group of clones, planting seedling tubers in a field test to measure resistance to infestation, and then bulking the seed from the most resistant clones to complete the selection cycle in one year. A population developed by five cycles of selection (five years) for resistance to infestation using this procedure resulted in a decrease of 57% in the level of infestation from the original population. |
