In a database system that allows for quick and accurate querying, PediTrack generates pedigrees in an easily understandable format. Other pedigree programs are available commercially, but are often expensive, specific to certain organisms, or unadaptable for specific programmatic use. PediTrack allows a personal computer (PC) user with Microsoft Access version 2000 or higher to use the simple program without charge. This software is widely available and easily adaptable to a variety of breeding program functions. PediTrack does not perform any calculations, so the initial program size is small (<2 megabytes). The program consists solely of the basic framework for housing pedigree information and reporting pedigrees based on those records.

Nineteen cultivars of muscadine grape (Vitis rotundifoli a Michx.) were divided into three classes based on the mean number of shoots developed during micropropagation. The cultivars in each class were then compared for pedigree similarities and common ancestors were identified. It was determined that the difficult to propagate class always had close direct lineage to either `White Male' or `Scuppernong', both selections from the wild. The intermediate class tended to be composed of newer cultivars which were more distantly related to `White Male' and `Scuppernong'. The easy to propagate class had diverse family histories and none of them included either `White Male' or `Scuppernong' for three or more generations. It is hypothesized that some factor, yet undetermined, has an influence on the ability of muscadine grape to be micropropagated.

Pedigrees of Wit', `Venus', `Viscount', `Vogue', and `Viva' sweet cherry cultivars (Prunus avium L.) were confirmed with pollen-incompatibility studies. `Hedelfingen', the maternal parent of the last four cultivars, was assigned previously to Incompatibility Group VII (S4S5); however, it was shown that Vineland `Hedelfingen' belongs to Group `O' (Universal Donors) rather than VII. Thus, the parentage of the above cultivars, with the exception of `Vic', is correct as reported when these cultivars were named. `Vie' pedigree is incorrect and it belongs to Group `O' rather than the previously assigned XIII. `Valera' also belongs to Group `O' and the existence of Group XIV (S1S5), with `Valera' as its only representative cultivar, could not be confirmed.

Since the 1930s, more than 130 inbred lines and 60 hybrid cultivars of onion have been released in the public sector in the United States. Other than breeder's reports from the period 1946-1965 and anecdotal information kept by onion workers, no systematic treatment of the pedigree of public onion germplasm releases has been developed. The objective of this research was to collect, characterize, and display the genetic relationships among more than 200 public onion germplasm sources used in the United States since 1931. Pedigree information revealed that most modern onion cultivars in the United States descend from a few open-pollinated populations brought to this country by immigrants. For example, selection in the open-pollinated populations Common Yellow and Silverskin by onion farmers in the eastern U.S. resulted in the formation of Yellow Globe Danvers, which was a precursor to virtually all Eastern storage onion germplasm in the U.S. Open-pollinated populations such Yellow Globe Danvers, Valencia, Sweet Spanish, Bermuda, and Grano formed the foundation germplasm for the first public U.S. onion breeding programs. Findings from this study suggest a relatively narrow germplasm base of public onion germplasm in the United States; however, this narrow pool coexists alongside significant gains through scientific breeding efforts, particularly during the past 75 years.

UniBase is a Windows-based (95, 98, NT, 2000, or XP) user-friendly software package that was developed for those who are interested in creating their own instant databases, add information to an existing databases or import data and images from Excel in a choice of languages. The software is very useful for germplasm inventory (fruit crops, vegetables, ornamentals, agronomic crops, weeds, chemicals, insects, pests, animals, etc.) and can be used in any breeding program (animal, horticulture, agronomy, etc.) to trace pedigrees and view images and characteristics of progenies. The database can be searched using various criteria and the use of several operators. An unlimited number of images can be stored for each entry and several graphic formats including BMP, JPEG, GIF, TIFF, etc., can be used. Additional information on UniBase and available data and images can be obtained from the authors.
