Title:
RFLP mapping of I1, a new locus in tomato conferring resistance against Fusarium oxysporum f.sp. lycopersici race 1
Publication date:
1991
Summary:
Inheritance and linkage relationships of a gene for resistance to F. oxysporum f.sp. lycopersici race 1 were analysed. An interspecific hybrid between a resistant Lycopersicon pennellii and a susceptible L. esculentum was backcrossed to L. esculentum. The genotype of each BC< sub>1 plant with respect to its Fusarium response was determined by means of BC< sub>2 progeny tests. Resistance was controlled by a single dominant gene, I1, which was not allelic to I, the traditional gene for resistance against the same fungal pathogen that was derived from L. pimpinellifolium. Linkage analysis of 154 molecular markers that segregated in the BC< sub>1 population placed I1 between the RFLP markers TG20 and TG128 on chromosome 7. The flanking markers were used to verify the assignment of the I1 genotype in the segregating population.
