XVI International Botanical Congess

Among the species of genus Lycopersicon the self-fertile L.hirsutum var.glabratum is the revolutionary intermediate form of transition from self-incompatibility to self-compatibility and is characterised by wide polimorphism on cross-pollination's degree both between and within specimens. The hybrids of self-compatible L.esculentum with more self-fertile plants of var.grablatum (in comparison with less ones) are of better viability, productivity, and show more range of phenotipical variability in next generations. Deviation is noted from the expected segregation toward the increase of the class of plants with the signs of wild form. It is supposed that one of the mentioned deviation is the selectivity of fertilisation which is controlled by different expressivity of self fertility alleles.
