Morfologi Mutan Alfalfa (Medicago sativa L.) Hasil Iradiasi Sinar Gamma Pada Cekaman Kering

Alfalfa in dry stress conditions cannot grow optimally. Drought inhibits growth and reduces alfalfa production many cultivation systems. Plants breeding with gamma-ray irradiation vitro selection using PEG found somaclonal variants adapted to well drought conditions. This study aims determine the type of mutation best morphology mutants resulting from gamma were sub-cultured vitro. cultured medium, according treatments. experiment used completely randomized factorial design 2 factors, namely doses (0 Gy, 100 200 300 400 500 Gy), concentrations (5%, 10%, 15%, 20% ). The variables observed viability, plant height, number leaves, wet weight, medium shrinkage, leaf wilting, color. results showed that gamma-irradiated mutant had a better (p<0.05) than control Gy) face Combination Gy concentration resulted mutant. Key words: alfalfa, vitro, rays,
