Abstract
From Regional (.NCRPIS) United (USDA) l.948 to 1986, the North Central Plant Introduction Station in Ames, Iowa maintained the states Department of Agriculture germplasm collections of Lycopersicon. Seed increases of Lycopersicon esculentum Miller and &· pimpinellifolium (Jusl.) Miller had been collected from field-grown plants with no controlled pollination and only limited effort to cull off-types, when they could be identified. Such methods have been successful in producing high-quality seed of many self-pollinating &· esculentum accessions, but the integrity of &· pimpinellifolium seed increases was questioned after the publication of research reports on the breeding biology of this species (Rick et al, 1977, 1978).
