Performance of some sunflower genotypes grown under dry weather conditions in south Bulgaria

Abstract

Information on yield and agricultural performance of new sunflower (Helianthus annuus L.) hybrids grown under dry weather conditions in South Bulgaria is limited. The objectives of this field study is to acquire information on seed yield and other agricultural characteristics of five sunflower hybrids and their parental lines in South Bulgaria. This research was carried out on the Experimental farm at the Agricultural University in Plovdiv, Bulgaria in the seasons of 2008 and 2009. Statistical analysis revealed that the differences among genotypes for all studied characters were significant in both seasons as well as in the combined one.
