Abstrakt
There is a need to expand the information on genetic
relationships between tomato (Solanum lycopersicum L.) lines to improve
hybridization breeding. The genetic diversity and relationships among 24
tomato lines were evaluated by simple sequence repeat (SSR) markers. A
total of 65 bands were generated with 15 SSR primers, of which 64 bands
were polymorphic. The mean polymorphic information content was 0.356.
There was a high degree of polymorphism between tomato cultivars. The
mean marker index and heterozygosity were 0.045 and 0.454, respectively.
Cluster analysis grouped cultivars into 6 main clusters. The cvs. Mo. H. P,
'C. C. Orange', and 'Marb' had the greatest genetic distance from other
cultivars and is suitable for hybridization to achieve maximum variability
for selection in segregating populations. The data can be used to select
appropriate parents in tomato hybridization breeding.
