Study and selection of Selenium-tolerant genotypes of the economically important plants Hordeum vulgare and Triticum aestivum

The aim of the study was to select selenium-tolerant genotypes of two economically important crops Hordeum vulgare (barley) and wheat Triticum aestivum (wheat). Selenium dioxide (SeO2) was used as source of selenium. One hundred and sixty three accessions of barley and 175 accessions of wheat were used in this study. Concentration of Se 10-3 M was selected for treating the different accessions of barley and wheat. Accessions of barley and wheat were found nontolerant 52% and 93% respectively. Root and shoot length inhibition was found in all the accessions. Mitotic anomalies were present in the selenium treated seedlings of accessions. Frequencies of epidermal cells and stomata, structural anomalies in stomata and selenium accumulation were observed in root and shoot of selenium treated accessions of barley and wheat.
