Abstract

The androgenetic ability of 85 Lycopersicon esculentum Mill. genotypes was tested. Callus was induced from anthers of 53 lines and hybrids. Regeneration of plants was obtained only from calli of 15 genotypes. The data obtained clearly showed that the genotype affects induced androgenesis in tomato. The in vitro response of anthers from the cultivars Roma, Pearson, San Marzano, Por, Sar, Vigapol, Day, David and Start, containing the ms 1035 gene, which is responsible for male sterility in tomato, confirm the strongly expressed dependence of both callus induction and organogenetic potential on the homozygous or heterozygous state of that gene. A protocol of callus induction, organogenesis and plant regeneration has been developed. More than 6000 regenerants have been obtained. Most of them showed different morphological alterations and variations in chromosome number (n, 2n, 4n). Some are interesting as source material for tomato breeding.
