Parthenocarpy in tomato (Solanum lycopersicum), its inheritance pattern and association with marker characters

Published on

Seedless tomatoes resulting from genetic parthenocarpy
would be beneficial in the food preparation and process
products industries. Present investigation was carried out
to determine the inheritance of parthenocarpy in tomato
variety ‘Oregon Pride’ and to examine its linkage with two
marker genes viz., stem pigmentation and leaf character.
Parthenocarpy in ‘Oregon Pride’ was facultative in nature.
Expression of parthenocarpy in three segregating
populations indicated involvement of an independent gene
designated as “ii”, which influenced the gene pat-2 having
major effect for the control of parthenocarpy. No linkage
was detected between parthenocarpy (pat-2 pat-2 ii ii) and
two marker genes, stem pigmentation (aw+/aw) and leaf
character (c+/c).
