  • $F_2$ populations of the crosses KC47-1 (PI244670) ${\times}$ KCB14-2-2-3-2 (PI201234), KC220-1 ${\times}$ KC268 and $F_3$ bulk populations of the crosses KC47-1${\times}$KC263 (AC2258), KC47-1${\times}$KCB13-2-1 (PI201232), KC47-1${\times}$KCB13-4-2 (PI201232), either one parent of which was resistant to Phytophthora blight, were tested for both gray leaf spot and Phytophthora blight by serial inoculation with Stemphylium solani or a mixture of S. solani and S. lycopersici, and P. capsici in 1999. In 2000, $F_3$ and $F_4$ lines or populations developed from the respective $F_2$ or $F_3$ selections in the previous year were evaluated for resistance to both diseases. A significant progress in resistance to both diseases was achieved by selection.
