Developing confectionery sunflower hybrids and determination of their yield performances in different environmental conditions

Abstract

Confectionery type sunflower grows generally in Eastern and Middle Anatolia in Turkey but there is no certified seed in the production which have white color with grey stripe. The study covered the confectionery sunflower hybrids developed in Confectionery Sunflower Breeding Project conducted by Trakya Agricultural Research Institute, Edirne, Turkey. The candidate confectionery hybrids were tested and evaluated in the regional yield trials in Trakya Region in 2009-2010. Seed yield, 1000 seed weight, flowering and physiological maturity period, plant height, head diameter, oil content were measured. Based on trial results; some experimental hybrids exhibited higher performance than controls for both for seed yield and seed weight and promising candidate hybrids were selected to send to registration trials. From these promising hybrids, 09 TRÇ 003 and 09 TRÇ 004 confectionery hybrid were sent to registration trials in 2011 2012, respectively and production permission were obtained for them. After evaluation of candidate hybrids in these years, having higher general combining inbred lines were also sent to National Registration Office for registration too. In 2010; two female line and three restorer (male) lines were sent to registration. In 2011; one female and one male line sent for DUS tests and then registration in 2012
