Abstract

A research work was conducted for seasons 2015, 2016 and 2017 (Three cycle of selection and selfing) at Damazin Agricultural Research Station Farm, Damazin, Sudan, located at longitude 34°22’ E, latitude 11°47’ N and altitude 470 m. The objective of research work is to provide new promising local sunflower genotypes (open pollinated varieties and hybrids) having high seed yield potential and adaptability for rainfed conditions in Blue Nile State area. The experimental materials consisted of two sunflower populations (DM-1 and DMHY) and two inbred lines (DM1-3 and DMHY-1). Unanalyzed field observations (primacy data) within each genotype just to assist in selection procedures were taken on days to 50% flowering, days to maturity, plant height (cm), head diameter (cm), seed set % and seed yield/plant (g).  As a result of improvement strategy research, about 20 new promising genotypes (lines) possess high seed yield potential under rainfed conditions and are available for further breeding objectives.

Keywords: Sunflower, Strategy, Open pollinated, Seed, constraint.
