     intergeneric cross was made between the cultivated sunflower inbred line ha89 and an accession of wild verbesina encelioides tolerant to drought and high temperature. the line was a bc2f5 progeny. the most remarkable feature of the plants was their compact architecture due to short petiole length and also, rather specific bright-yellow inflorescences. similar plant architecture did not exist in either the wild or the cultivated parent. for sunflower, it is considered as a favourable and potentially useful adaptive trait. the line was multi-branched of medium type branching and possessed good agronomic characteristics. the overall characteristics of ha-verbenc line make it a useful plant material for research on wide hybridization.
