Six enzyme systems were surveyed in 12 peach cultivars using polyacrylamide gel
electrophoresis of leaf extracts. Variation between cultivars was observed in four enzymes:
peroxidase, isocitrate dehydrogenase, acid phosphatase and alkaline phosphatase. Genetic
variation parameters revealed that the maximum proportion of polymorphic loci was 46.1%.
Out of 15 loci studied, 9 were monomorphic and 6 were polymorphic for 20 alleles. A
dendrogram showed the grouping of cultivars on the basis of genetic distance values. The …

Six enzyme systems, viz. esterase, peroxidase, isocitrate dehydrogenase, malate
dehydrogenase, acid phosphatase and alkaline phosphatase, were surveyed in 12 peach
cultivars (Alton, Flavor Crest, Flordasun, Foster, Golden Bush, July Elberta, Kanto-5,
Nemaguard, Rich Haven, Shimuzuhakuto, Stark Red Gold and Sun Haven) using
polyacrylamide gel electrophoresis of leaf extracts. Variation between cultivars was
observed in four enzymes: peroxidase, isocitrate dehydrogenase, acid phosphatase and …
