Abstract

The aim of the research was to investigate the statistical methods used in reporting quantitative genetic models in flower, vegetable, fruit, grape, and shrub and tree studies. A systematic literature review was performed in June 2008 on Oxford Journals database. The search methodology was developed, the inclusion criteria of the titles in the study were imposed, and the variable of interest were defined. A number of four-hundred and thirty-five titles were identified by applying the search string. Thirty-five titles accomplished the inclusion criteria and were included into the study. The analysis of results revealed that almost one-third of paper did not have any keywords and the most frequent one was quantitative trait loci. More than fifty percent of the papers included into the results descriptive statistic parameters and frequencies. Less than half of the investigated papers used any method of statistical inference in analysis of the results. A comprehensive analysis is needed in order to investigate the trends of statistical methods reported by quantitative genetic studies on studied fields by inclusion into the study a wide range of available databases.
