The genetics of blackarm resistance - VI. Transference of resistance fromGossypium arboreum toG. Barbadense
A strong, partially dominant gene governing resistance to blackarm disease (Bact. malvacearum) has been transferred fromGossypium arboreum toG. barbadense (Domains Sakel). The new gene,B4, segregates independently ofB1,B2, andB3 and it shows additive effect in conjunction withB2 and withB3.
Three cytogenetically distinct techniques for transferring genes from Old World diploid to New World allopolyploid cottons are described and their relative merits discussed.
