Band designs of esterase (EST), peroxidase (PO) and polyphenol oxidase (PPO) isozymes in several selected cultivars of Catharanthus roseus by using native polyacrylamide gel electrophoresis (PAGE) were investigated in this study. It was confirmed that cultivar differences in isozyme polymorphism can be revealed by applied electrophoretic patterns. Three isozyme systems produced a total of 16 bands with polymorphism ranged from 66.6-100%. Considering the patterns of isozyme variations in the five cultivars of Catharanthus roseus, it is evident that the cultivar ‘First kiss coral’ displayed crim

Twenty-two cultivars of Kentucky bluegrass (Poa pratensis L.) were examined for their glucose phosphate isomerase, triose phosphate isomerase, phosphoglucomutase, malate dehydrogenase, 6-phosphogluconate dehydrogenase and alpha-naphthyl esterase phenotypes. Polymorphism was observed in each isozyme system, and the first four systems were characterized for variation among and within the cultivars. Sixteen of the 22 cultivars could be uniquely identified by selecting isozymes which displayed clearly resolved bands and exhibited little or no intracultivar polymorphism.

Forty-one (Mangifera indica L.) cultivars were characterized electrophoretically using the isozyme systems aconitase, isocitrate dehydrogenase, leucine aminopeptidase, phosphoglucose isomerase, phosphoglucomutase, and triosephosphate isomerase. The outcross origin of some of the mango cultivars was supported by the isozymic banding patterns. Reported parentage of some other cultivars was not consistent with their isozymic banding patterns.

Context: Pumpkin (Cucurbita maxima) is highly polymorphic vegetable species and its polymorphism can be analyzed by isozyme molecular marker. Objective: To analyze genetic polymorphism among 10 locally grown pumpkin cultivars by isozyme.

Abstract Genetic analysis of 11 allozyme polymorphisms was performed on the progeny of ‘Cayuga White’ × ‘Aurora’, two complex interspecific grape (Vitis) hybrids. Segregation for most of the polymorphisms closely approximated monogenic Mendelian ratios, and eight new isozyme loci were defined for grape. Joint segregation analysis among the isozyme loci revealed three multilocus linkage groups. These results demonstrate that sufficient allozyme polymorphism exists in grape to establish many multilocus linkage groups and that this genetic analysis can be accomplished using extant progeny or prog

Genetic diversity of 33 Elymus caninus accessions was investigated using isozyme, RAPD, and microsatellite markers. The three assays differed in the amount of polymorphism detected. Microsatellites detected the highest polymorphism. Six microsatellite primer pairs generated a total of 74 polymorphic bands (alleles), with an average of 15.7 bands per primer pair. Three genetic similarity matrices were estimated based on band presence or absence. Genetic diversity trees (dendrograms) were derived from each marker technique, and compared using Mantel's test.
