Abstract

This research paper aims to investigate the mutagenic efficiency of Tambureşti and Venus groundnut varieties treated with X rays. Mutagenic efficiency is a measure of how often mutations result from the report between the number of punctual mutations and mutagenic dose applied. It is used to assess the effectiveness of each treatment with mutagenic factors used in breeding programmes. The assessing of mutagenic efficiency in the mutagenesis works allows breeders to identify useful treatments for obtaining the highest possible hereditary variations. The frequency of morphological changes was higher in Tamburesti variety in smaller doses (5.9% in 6000r and 4.1% in 5000r), while Venus variety presented same type o f frequency in bigger doses (8.7% in 9000r and 7.5% in 10000r).Mutagenic efficiency was observed to both varieties, in different doses, thereby ensuring the highest percentage of survival and pods formation.
