RESPONSE OF LINES OF CAPSICUM SPP. TO ITALIAN POPULATIONS OF FOUR SPECIES OF MELOIDOGYNE
AbstractThe reactions of lines of Capsicum baccatum, C. baccatum var. pendulum, C. chacoense, C. chinense and C. frutescens to Italian populations of Meloidogyne incognita, M. javanica, M. arenaria and M. hapla were evaluated in glasshouse. Groups of eight plants of each line were transplanted in trays with 12dm³ of sterilized sandy soil artificially infested with 5,000 eggs and juveniles of each nematode species per plant. Two lines of C. chinense and one of C. frutescens were resistant to all Meloidogyne spp. tested. Seven lines of C. chinense, and one of C. chacoense were resistant to M. incognita, M. javanica and M. arenaria; one line of C. chacoense and two of C. chinense were resistant to M. incognita and M. arenaria. Three lines of C. chinense were resistant to M. incognita and M. javanica. One line of C. chacoense, four of C. chinense and five of C. frutescens were resistant only to Mo incognita, while three lines of C. baccatum, eight of C. baccatum var. pendulum, nineteen of C. chacoense, and ten of C. frutescens were susceptible to all four species of the root-knot nematodes.
