Abstract
Studies were conducted on the resistant gene from a wild tomato relative L.peruvianum against tomato powdery mildew, controlled by a nuclear, dominant gene (RL-4). Using BSA and AFLP technique in F2 population,and six AFLP markers that were linked to the resistant gene were obtained, the genetic distances were 4.3, 5.5, 5.5, 5.6, 6.6 and 11.9 cM, respectively.
A significance statement is not available in the OpenAlex record.

Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
