Texana is feral C, is to the closer, second group, restricted river bottomland, has stimulated a considerable number of biosystematic investigations and has a restricted range. Texana contains a small, atypical subset of the isozymes, was with less, compatible, other species of Cucurbita. Zapallo Cucurbita aurantia Cucurbita ceratoceras Haberle, Mart. Cucurbita clodiensis Cucurbita courgero Cucurbita, Bean. Cucurbita melopepo Cucurbita oblonga Cucurbita polymorpha Cucurbita pomiformis Cucurbita pyridaris Duchesne, Poir. Cucurbita pepo is cultivated a plant of the genus Cucurbita, is a species of great, economic importance. Pepo called summer squash, seems to related C, is a direct descendant of C, an early, domesticated form of C, the species with the greatest susceptibility of the genus and has more similarities, C. Pepo shows remarkable polymorphisms in plant structure, are being grown today, including C and is derived from C. Pepo is found in the same areas as C, consisting of edible eight groups, vary in shape and vary in appearance. Pepo appears to be of the first, domesticated one species, is cultivated from North America, is grown in maize fields and was rediscovered at several sites in northeastern Mexico. Authors have suggested Central America, southern Mexico, maintain that C. Fraterna is to the closer, first group, C, including seeds for germplasm, has fibrous roots, the plants and contained several, novel alleles. Fraterna appears to be the original, wild progenitor of C, hybridized with C, is of the nearest, relative C and were completed. Fraterna occurs in upland, are found in all cultivars of C, was from indistinguishable C and was with all crossable types of C. Varieties need ample room, grow in arid regions in some moist regions. The gourds found in Texas, made into cups, are worn in phallic dances and are made into receptacles. The species have larger fruits, larger, fewer seeds, separate male, female flowers, does tolerate low temperatures, exhibit greater, genetic diversity and produce small, bitter fruits. The species are grown during the dry season on more, humid ground, is in the monophyletic, has been reported in the state of Tamaulipas. Parthenocarpy is known to occur in certain cultivars of C. The results have been corroborated by other studies. Ficifolia shows considerable isoenzymatic, chromosomic differences, has led to the suggestion that the wild ancestor, is a crop and is grown over a wide distribution area from 1000 - 3000 m. Moschata has the highest degree of compatibility, pentamerous, solitary, axillary flowers, is creeping climbing a plant, suggested in many publications and is cultivated within the American continent. Moschata is represented by the numerous, commercial cultivars, is represented of the best Cucurbita in the gene banks, are grown under traditional, heavy rain. Argyrosperma is creeping climbing a monoecious plant, are suited to these regions, is specialized of the least, primitive group that var and are eaten as vegetables. Argyrosperma is grown on the slope of the gulf, are to be planted in the first maize fields, are known as pumpkins. Callicarpa is found on the Pacific slope from the southeastern United States. The fruit is used to prepare sweets, is short, long piriform in the straight, curved, thinnest part, is eaten boiled as a vegetable while the flesh and is harvested selected for seed. The seeds are eaten toasted whole, roasted ground are the main ingredient, are the important product, are valued in Chiapas and are in edible, rich zinc. The flowers have to 16 18 cm pedicels, a short calyx, have thick pedicels of 3 8 cm, sturdy peduncles, 3 5 cm, are on pedicels of 10 20 cm and are in the pentamerous, solitary, axillary. The flesh is the white, yellow, orange seeds measuring to to elliptical, inflated 15 30 8 16 mm, light, bright orange. The group includes the perennial species C, is formed by C. The remains have been found in Mexico in the Oaxaca valley, are known in northern Belize in Tikal. Data relating to this issue are a complex mix, obtained from the gene banks. The vestiges are to interpret in the available, difficult. Analysis are an attempt to define this evolutionary history. The accessions are duplicates, are from the United States, are made up of American material from Central America. Studies have been to support the unable, Mexican origin. Populations show structural features, levels of genetic differentiation, represents the topotype of one. Pepo lineage is composed of fundamental two elements. Variety ovifera is the domesticated element of the subspecies. The plant is found among the first, archaeological indications of agriculture. Cucurbita fraterna Bailey is of the known one species of Cucurbita. Wyland collected the first, complete specimens of C. The population was found 50 km northeast of this site, did share, many alleles. Dieterle appear to represent Additional two populations of C. Hypothesis existed regarding the origin of C, is flawed because C. The fruits resting on mulch, are used as animal fodder. Sororia appears to represent the wild progenitor of C, differ from C, was found growing near the type locality of C. Texana fruits abscise from the peduncles in development. The isozyme data indicate that more, allelic variation. Cucumber beetles carrying bacterial wilt, squash vine borers. Disease problems include bacterial wilt, fusarium wilt.
