Abstract

Genetic resistance, together with the application
of antinematode products and other methods of integrated
fight, is the most recommended control choice. Many modern
varieties and hybrids have introduced Mi gene, that confers
incomplete resistance to several species from genus
Meloidogyne. The National Institute of Agricultural Sciences
(INCA), along with La Mayora-CSIC Experimental Station, has
developed a breeding program, with the objective of
introducing the Mi gene to a few tomato varieties with good
acceptance by Cuban producers. The methodology used was
marker-assisted selection by using Aps-11, an isozyme marker
that integrates the same linkage group as Mi gene. Codominant
marker Aps-11 helps the indirect selection of nematode
resistance, with no need of infesting the soil. The selection by
Aps-11 during backcross and selfing process made between
1997 and 2003 enabled to obtain Aps-11/Aps-11 lines. This paper
reports the first results of incorporating Mi gene to tomato
varieties Mariela, Amalia, Rome and Rilia as well as describes
the methodology followed.
