Summary

Genetics of parthenocarpy in cv ‘Severianin’ was tested under natural low-temperature conditions under which only seedless fruits were produced. Results were consistent with the hypothesis that two recessive genes are involved in the expression of parthenocarpy under low-temperature conditions. One gene, pat-2, has major effects on the expression of parthenocarpy. A second gene, mp, in the homozygous form, influences expression of pat-2 in both the homozygous and heterozygous conformation and may be present in non parthenocarpic phenotypes. Linkage tests, using 26 morphological marker genes, located pat-2 between ‘solanifolia’, sf (chromosome 3 site 111) and baby-lea syndrome, bls (chromosome 3 L site 74) close to sf. The location of the minor gene for parthenocarpy, mp, was not detected.
