“…An examination of the inheritance of the epidermis in processing cucumbers, and the identification of specific molecular markers linked to it could lead to improved quality. Fanourakis and Simon () concluded that the expression of palisade or flat epidermal cells was determined by a single gene, and that the ratio of palisade:flat was 3:1 in an F 2 population, suggesting monogenic inheritance with dominance for palisade epidermal cells. The gene was named Pe (Fanourakis & Simon, ) and was mentioned in the gene list for cucumber (Wehner, ).…”

Firmness of skin is an important quality of processing cucumbers, which is a feature of the palisade epidermis in these types compared to flat epidermis in fresh cucumbers. This study was conducted to map the Pe (palisade epidermis) and analyse the candidate gene. Populations derived from the cross of two inbred lines, NCG122 with fruit flat epidermis and NCG121 with fruit palisade epidermis, were used to identify the inheritance of palisade epidermis and to map the gene involved in its development. The results showed that the palisade epidermis trait is controlled by a single gene, Pe, that is dominant over flat epidermis. Seven simple sequence repeat (SSR) and five insertion deletion (Indel) markers were identified to be linked to the Pe gene. It was mapped to cucumber chromosome 5 (Chr.5) between SSR14611 and Indelpe12 with genetic distances of 0.3 cM and 0.2 cM, respectively. The physical distance of the genomic region harbouring the gene was 227.5 kb with 26 predicted candidate genes. The accuracy of marker‐assisted selection using the molecular markers, Indelpe12 and SSR14611, was 68% and 88%, respectively.

The inheritance of cucumber fruit neck size and its linkage relationships with the fruit length and 10 other characteristics was investigated . Frequency distributions and the means of generations indicate intermediate inheritance for neck size and fruit length . Correlation and regression analysis suggest strong linkage between fruit neck size and fruit length . Chi square analysis of the F2 and BC generations indicate independent assortment of the fruit neck size and the following characters : bitterness, female sex expression, spine color, spine size, warted fruit, uniform color of immature fruit, mature fruit color, dull fruit skin, epidermal structure, and powdery mildew resistance .

Genetic analyses were conducted among 18 provisionary isozyme loci in Cucumis sativus L. Fourteen loci demonstrated simple Mendelian inheritance while observed variation at four loci (Gpi2, Gr2, Pgm3, Skdh2) was determined not to have a predictable genetic basis. Joint segregation analyses among the 14 genetically predictable polymorphic loci resulted in the assignment of 12 loci to four linkage groups. Linkage groups contain the following loci: (1) Gr1, Pgm1, Idh, Pgd1; (2) Pep-pap, Mdh2, Mdh3, Gpi1; (3) Pep-la, Per4; (4) Pgd2, G2dh. Mpi2 and Mdh1 segregated independently. Recombination fractions for linked loci ranged between 0.051 (Pgm1-Idh) to 0.385 (Pep-la-Per4). Some practical applications of isozyme marker loci for cucumer improvement are discussed.
