DETERMINATION OF THE AGRICULTURAL CHARACTERISTICS OF THE POLE FRESH BEAN POPULATION IN GREENHOUSE
MetadataShow full item record
In this study, improvement of pole fresh bean populations gathered from the Middle Black Sea Region was attempted using pure-line selection method under greenhouse conditions. The aim was to regain the populations that have lost their distinctive typical properties through breeding and bring them into use of local farmers. Fresh pole bean populations collected from Carsamba Plain of Middle-Black Sea region in 2003 were evaluated in terms of their agricultural characteristics under greenhouse conditions. In 2006 observation gardens were established in greenhouses; pre-yield and yield experiments were performed in the following 3 years (2007-2009). Eleven lines were selected according to UPOV criteria. In addition to best phenological and morphological traits being presented by C4-3. TK9-4 and TK43-4 lines in comparison to the control varieties; C4-3, TK43-4, L4 and TK50-3 lines outperformed the control varieties in terms of yield following stage 1 and stage II regional yield experiments on 11 lines between 2010-2011, and certain lines were selected to be candidates for certification.
