landscaping purposes. Attempts to improve Buddleia davidii using conventional breeding methods have resulted in limited success ( Tobutt, 1993 ). Different ploidy levels of species in the genus Buddleia may impede the interspecific crosses; therefore

. However, successful hybridization between species outside of the section Cyanococcus with either cultivated or uncultivated members of the Cyanococcus section has been less frequent. Thus, it is intersectional crosses and not interspecific crosses that

. Supporting this association between seed number and fruit size and development period are cases where interspecific crosses have been compared with crosses that were either self- or cross-pollinated. Aalders and Hall (1961) found reduced seed set in lowbush

. Artificial interspecific crosses among chestnuts have been used to introgress disease and/or pest resistance traits in chestnut breeding programs (e.g., Clapper, 1954 ; Diller and Clapper, 1969 ). Molecular markers such as allozymes also have been applied
