โœฆ Synopsis

Nine polymorphic isoenzymatic systems were studied in 39 cultivated sunflower populations originating from ten countries. Analysis of combining abilities with four tester lines was also performed on these populations for seed yield, seed moisture and seed oil content. The MDH, PGI, PGD and GOT systems appeared to provide the best discrimination of specific combining ability effects with the four testers. The MDH and GOT systems provided a between-population structure that was consistent with the country of origin.
