Estimation of proline content in advance mutant lines of oat (Avena sativa L.) under water stress condition

Abstract

In this study, we evaluated proline accumulation profiles in leaves of mutant oat (Avena sativa L.) plantlets under water stress. Oat plantlets were observed to accumulate proline in leaves, stems and leaves during water stress. The study is conducted in 30 mutant lines of oat along with three checks JO-1, JO 03-91 and Kent under water stress condition. Results indicated that mutant line has proline content of 36.71 (micro gram per gram) of fresh leaf weight, which is higher than check JO-1 that has proline content of 35.10 (micro gram per gram) of fresh weight leaf, so that it is advantageous to select the mutant line MJ9315-17 for water stress or drought condition.
