Abstract
In this paper we describe an intergeneric hybrid between H. annuus (HA 89) and T. rotundifolia obtained by normal pollination of a male-sterile cultivated sunflower. The hybrid had a combination of morphological traits from both parents; it was unbranched and exhibited male-sterility. The plant did not produce viable achenes when pollinated with HA 89. DNA fingerprinting through the AFLP methodology exhibited 240 polymorphisms and confirmed the hybrid nature of the experimental plant. The genetic distance analysis discounted the phenomenon of partial hybridization.
