| Today, consumer awareness on the healthiness of their foodstuff increases. The main focus is on secondary metabolites and antioxidants. Broccoli (Brassica oleracea L. convar. botrytis Alef. var. italica Plenck) has many compounds beneficial for human health, like Vitamin C, Carotionoids or Anthocyanins. To investigate these compounds two techniques are used in this study which are non-destructive sensor measurements (Multiplex®) to determine the value of anthocyanins (ANTH_RG) and flavonols (FLAV) and measurements of the antioxidant potential (water- (ACW) and lipid- (ACL) soluble antioxidants) on the basis of chemoluminescence. Field trials in autumn of 2011 and spring of 2012 were conducted in a randomized block design with different broccoli genotypes,... |

| Ziel des Projektes war, Zuchtpopulationen bzw. traditionelle, offen blühende Brokkoli-Sorten (keine Hybriden bzw. CMS-Hybriden) speziell für den Ökologischen Landbau zu prüfen. Wichtige Eigenschaften waren dabei Ertragssicherheit, Einheitlichkeit, enges Erntefenster, Festigkeit der Blume sowie hohe Gehalte an sekundären, bioaktiven Inhaltsstoffen, insbesondere von Glucosinolaten. Um eine schnelle und kostengünstige Möglichkeit zum Screening von bioaktiven Inhaltsstoffen zu entwickeln, die für den On-Farm-Einsatz geeignet ist, wurde zudem ein zerstörungsfrei arbeitendes Sensortool getestet. Während der dreijährigen Projektlaufzeit erfolgten On-Farm-Selektionen geeigneter Brokkolilinien/-sorten auf Kultursaat-Zuchtstandorten sowie auf der Versuchsstation für... |

| Starting from identified breeding populations of broccoli, new open-pollinated broccoli varieties (OP varieties) are to be developed by means of two intensive individual selection steps with progeny testing in an on-farm approach. These new varieties are to meet the demands of organic vegetable production. To achieve this, agronomic characteristics such as yield stability, uniformity, short harvesting period, sufficient firmness of the head are sought after, coupled with good sensory characteristics and high amounts of bioactive substances beneficial to health and excellent taste. |
