The temperatures ranged from 22.1˚C to 35.5˚C lower temperature and the highest temperature achieved in the above-day interval. The average value calculated for highest temperature was 32.9˚C and 24.9˚C for the lowest temperature recorded daily. The vegetative characteristics variance analysis sheet has not found significant contrasts between local cultivars, but detected at least a significant contrast to the 1% level of probability between subplots: petiole length, the longitudinal length of the sheet, transversal length of the sheet and the total sheet length .For fruit weight characteristics , longitudinal length of the fruit ,transverse length , longitudinal/transverse length ratio , shell thickness, the data were significant for the subplots, demonstrating that at least one family of half-sibling is different in 1% level of significance. The LLFr characteristics,CFrL, L/T RFr,dutch bucket hydroponic flesh thickness and cavity diameter were significant in Px S interaction, which may indicate that among the cultivars there is a difference sites.
The genetic divergence among pumpkins access is based on morphological characteristics.Nine descriptors were analyzed . The results indicated a high degree of genetic variability, having no relationship between the collection site and the formation of the group of similarity. The greatest contribution of variables to genetic divergence was diameter greater fruit and fruit diameter of the inner cavity in longitudinal and latitudinal direction.Works with several Cucurbitaceae were also developed by other authors , where the fruit morphological characteristics and seeds for some species were evaluated. The results showed that most variable characteristics are the shape, color and fruit size, and shape and seed size.All data for the total number of fruit characteristics , total weight of fruit and average fruit weight were significant, and at least one half sibprogeny is different from the others.This means that the half sib progeny are statistically different. The results for interaction Plots × Subplots were significant at the 5% level only for AFrW characteristic .
The featuring 36 native populations of cultured pumpkins C. moschata and C. argyrosperma was made and it was found that the variability can be explained based on specific uses regional fruits and seeds . Quantitative characteristics that explain part of the variation found were: width of the fruit pulp, width and length of the fruit; width,length and weight of 100 seeds, and, days of female flowering. The variability is attributed to seed selection criteria made by farmers and housewives, house and the cross-pollination nature of the species with pollinated by bees. Both forms of use such as the management practices have allowed the genetic variation of C. moschata is conserved and is a continuous source of variability .Further research also contributed to characterize the variability of the Cucurbita ge nus, dutch buckets system in order to discriminate material collected at fairs, markets, family farming and access of Banks Germplasm national research institutions. In the estimation of phenotypic, genotypic and environmental correlations for seven morphological characteristics seven pumpkin accesses found that the genetic correlations were higher than the phenotypic and environmental, indicating moderate influence of the latter in the expression of the characters . Sixty-five BAG Cucurbita accesses have been characterized morphologically by suitable descriptors, those recommended by the International Plant Genetics Resources Institute .
Highlighted the need for morphological characterization activities, through the use of a descriptive list provides further information about the germ plasm maintained .A study was conducted to estimate the genetic divergence in 16 pumpkin accessions of the Embrapa Semi-Arid Germplasm Bank of Cucurbitaceae , based on morphological and agronomic characterization to guide breeding work with the species. The material investigated was found high genetic variability, where the variables that provided greater contribution to determine the genetic divergence were: larger diameter and fruit diameter of the inner cavity of the longitudinal and latitudinal fruit . The Correspondence Analysis pointed to two main axes to explain the variation between samples collected for the qualitative characteristics: a. fruit shape; b. main color of the shell; c. secondary buds; d. color of the fruit pulp; e. design produced by the secondary color of the shell; f. bark texture.
