“…Cucurbita germplasm has received similar attention by Chinese researchers (Chen 1993;Zhou et al 1995;Ren 1998). Other reports on horticultural evaluations directed toward the identification of superior genotypes among local landraces include studies of Cucurbita landraces from Cuba (Rios Labrada, Fernandez Almirall, and Casanova Galarraga 1998) and Jordan (Kasrawi 1995) and of C. melo landraces from India (Seshadri and More 2002), Italy, and Albania (Ricciardi et al 2003).…”

“…Of all the species of the Cucurbitaceae, Cucurbita pepo is perhaps the most polymorphic one and one of the most polymorphic of the plant kingdom (Naudin, 1856). Moreover, a large diversity in 17 morphological and horticultural traits among the tested summer squash landraces was observed (Kasrawi, 1995). In our experiment, the small number of vine types (only a single landrace was observed) in the collection could be attributed to the replacement of vine landraces by the modern bush cultivars.…”

“…The green base of petals is governed by the Gb gene which is dominant to the plant with no band (Dutta and Nath, 1972). On squash, leaf silvery trait is possibly under genetic control (Kasrawi, 1995).…”

Plant identification and genotyping within a germplasm collection are important elements in planning a breeding program that can improve the development of plants with desirable market characteristics. In the current study, 20 squash (Cucurbita pepo L.) landraces were collected and identified from different areas in Egypt to investigate the plant diversity and genetic variations based on differences in plant morphology and the International Union for Protection of New Varieties of Plants (UPOV) descriptors. A total of 24 quantitative and qualitative morphological differences characterized the genetic variability among genotypes. The demonstrated variability among all the tested landraces suggested a large number of genotypes within the squash lines. The results showed the potential of morphological markers for the identification and assessment of genetic variations among squash landraces and provided a number of choices for planning a successful breeding program to improve squash landraces. The obtained results on the 20 studied genotypes established that the agronomic traits based on morphological traits and UPOV descriptor data provide cost-effective preliminary tools for genotypic varietal characterization and evaluation for breeding purposes. Moreover, the utilization of these neglected local squash landraces and the subsequent improvement can increase the diversity in the food marketplace at the local level and enhance agricultural biodiversity.

“…This might be caused by limited cultivation of C. argyrosperma in this country, as it was known by few individuals of Mbazwana and Mseleni villages at Umkhanyakude district only. It could also result from this landrace becoming extinct from all parts of South Africa and is rarely grown by communities; as in accordance with the study of C. pepo landraces in Jordan [19]. Therefore its conservation and improvement is essential.…”

Ethnobotanical knowledge on local Cucurbita landraces was documented in three district municipalities of northern KwaZulu-Natal, South Africa. Seven distinct landraces of C. argyrosperma, C. maxima and C. pepo were identified by local (isiZulu) names as iNhlwathi emhlophe, iNhlwathi emnyama, iPhuzi, isiPhama, iThanga, uMpampini oluhlaza and uMpampini ophuzi. The majority had leaves with silvery-white mottling in axils of leaf veins, but isiPhama and uMpampini oluhlaza had uniformly green leaves. INhlwathi emhlophe and iNhlwathi emnyama had the largest fruits and isiPhama had the smallest. Landrace iNhlwathi emnyama maintained its green fruit colour at maturity, while iPhuzi changed to uniform yellow/orange fruit colour before maturity. The isiPhama, uMpampini oluhlaza and uMpampini ophuzi had sparse to moderate stem branching habit and the sweetest, less watery fruits of them all. Seed colour ranged from cream to white. This study was the first attempt to record the genetic-related diversity on types of Cucurbita landraces that are grown in South Africa. It also recorded the presence of C. argyrosperma for the first time in this country.
