Information × Registration Number 0214U003119, 0111U003080 , R & D reports Title Based on the latest methods of breeding sterile and fertile lines to create a competitive F1 hybrid carrot with resistance to biological and abiotic factors of the Northern Forest-Steppe and Woodlands of Ukraine popup.stage_title Head Tkalich Yuriy Vadimovich, Registration Date 20-01-2014 Organization Research station "Mayak" Institute of Vegetebles and Melons, UAAS popup.description2 As a result of selective breeding created in 2012 and submitted for registration with the National Center for Plant Genetic Resources Ukraine promising fertile line of carrot seed Svoboda of high levels of performance, keeping quality and high combining ability. Root length 21-23 cm, diameter 4.0 cm , index form (ratio of root length to its diameter) - 5.6, core diameter 2.0 cm, which is 50% relative to the total diameter of the root. The total yield of roots 40.2 t / ha, product yield - 36.5 t / ha, 92% marketability . The average weight of a single commodity of root 200 g carotene content is 17.4 mg%. Keeping quality during winter storage - 93 %. Appointment line: pollinator when creating heterotic F1 hybrids of carrots , the parent component. As a result of selective breeding created in 2013 and submitted for registration in the National Centre for Plant Genetic Resources Ukraine fertile line of carrot seed Churayivna with high combining ability. Root length 23-25 cm, diameter 4.0 cm, index form (ratio of root length to its diameter ) - 6.25, core diameter 1.8 cm, which is 45% relative to the total diameter of the root. The total yield of roots 42.8 t / ha , product yield - 39.8 t / ha, 93% marketability. The average mass of one commodity 230 g of root Keeping quality during winter storage - 91%. Appointment line: pollinator when creating heterotic F1 hybrids of carrot seed, the parent component. A comprehensive assessment are based on the accelerated method (Patent for useful model № 37570) sterile lines of carrot seed (A): World Cup - 3/ 98 - 1P, World - 1/ 98 - 1P, World - 5/ 98 - 1P lines and Fixer sterility ( B): CHF-3/98-Z, CHF-5/98-Z that subsequently will be involved in the selection process of establishing heterotic hybrids F1. For complex traits in selected nursery Collectible source of productivity and quality among the collection of samples of carrots, which are recommended as the initial form to create fertile lines C: Karlena (K -287 ), Red Giant (K -294 ), Chantenay RA (K -283 ), and the Royal Chanson (K- 303). Active selection work to create fertile lines of carrot seed . For complex traits in the breeding nursery selected the best fertile line: Torch, CHFP/09 and CHF-OK/10. Lines will be involved in the process of establishing heterotic F1 hybrids of carrot seed . In hybrid nursery for complex traits are selected hybrids (CHS-3/98-1P 's Lange Rote Stumpf) F1 (K -910), (CHS-3/98-1P Berlikumer) F1 (K- 922), (world cup 3/98-1P Skarla x ) F1 (K -915 ) and (CHS-3/98-1P 's Krasny velikan) F1 (K -912), which exceeded the standard for productive and morphological and biometric characteristics. By Culture II was held breeding ste rylnyh line, fixer sterility and fertile lines, hybridization area obtained hybrid seeds prospective combinations. The research developed guidelines on heterosis breeding of carrot seed, which sets out new approaches in creating original material for heterosis breeding of carrot seed: accelerated creation sterile lines and lines fixer sterile and fertile lines selection method, described by a linear material carrot seed selection DS "Mayak" IVM NAAS.
