dc.description.abstractENGLISH ABSTRACT: This thesis consists of two articles for publication. The first is a review of sweet potato as agricultural crop and a review of breeding in South Africa before 1950, between 1950 and 1980, and after 1980. This includes a description of the polycross and mass selection methods introduced after 1980, and a critical review of published heritabilities and genetic correlations. The second article deals with the results of analyses of observations in trials undertaken to investigate genetic polymorphism in tuber characteristics, predicted selection response and genotype-environment interaction.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Hierdie tesis bestaan uit twee artikel vir publikasie. Die erste artikel is 'n oorsig van patats as landbougewas en die teling daarvan in Suid_Afrika voor 1950, tussen 1950 en 1980, en na 1980. Dit sluit die omskrywing in van die polikruis en massaseleksie metodes wat na 1980 onderneem is, asook 'n kritiese oorsig van gepubliseerde oortreflikhede en genetiese korrelasies. Die tweede artikel handel oor die resultate van waarnemings in proewe wat onderneem is om genetiese polimorfisme in stoorworteleienskappe te ondersoek, voorspelde seleksieresponsie en genotipe-omgewing wisselwerking.af_ZA
