Genetics of parthenocarpy in line RP 75/59 was tested under natural low temperature conditions, under which only seedless fruits were produced. Results were consistent with the hypothesis that three recessive genes with additive effects are responsible for parthenocarpy. Linkage studies, using 40 morphological marker genes located among all tomato chromosomes except chromosome seven, revealed linkage of one gene to diageotropica (dgt) located on chromosome 1 L site 152, and a second gene to yellow verescent (yv) located on chromosome 6 L site 34. Location of the third gene involved in parthenocarpy could not be determined. To calculate the power of the linkage tests, a simulation was carried out for three genetic models; the results are presented graphically in two figures.
