Biological features and elements of the technology of seed production of marigolds (<i>Tagetes patula</i> L.) in the conditions of the Southern Urals

Relevance. One of the priority areas research at Heterosis Selection LLC is creation varieties and development regional agricultural technology for growing seed material flower crops. The article represents results study intravarietal variability according to 7 structural features marigolds (Tagetes patula L.) cv. Elena Prekrasnaya under conditions Southern Urals. To develop a methodology production in Urals, it necessary complex morphological identify those that more fully contribute preservation maintenance variety. Results. As result variability, was found most stable traits variety are height plant, diameter inflorescence, number seeds inflorescence. Efficient selection when obtaining original will be focusing on signs plant inflorescence diameter. In order obtain high-quality industrial marigold should kept mind period from August 20 September 1, half potential yield ripens – 49.4%. greatest uniformity ripening (37.3% total yield) noted 1. harvesting inflorescences during this provided with high sowing qualities.
