LABORATORY ASSESSMENT OF POTATO RESISTANCE TO PHYTOPHTHORA INFESTANS
Abstract
Resistance breeding is a very important alternative to chemical control of late blight. Many resistance (R) genes from the wild Solanum species have been discovered and introduced into the cultivated potato. The laboratory methods to assess the resistance to late blight such as tests on detached leaflets, leaves, tuber slices, or whole tubers, are easy, cheap, fast and provide a good estimation of resistance that can be further con-firmed in field trials for the selected material. Laboratory assessment is particularly useful for materials, in which major resistance genes segregate and the resistance is qualitative rather than quantitative.
