Regarding drought tolerance, Tewary et al.(2000)
screened five selected mulberry genotypes such as G2, G3,
G4, S13 and S34 for osmotic stress using 1.0-10% poly-ethylene glycol (PEG) to simulate osmotic stress using 14
different media combinations. Out of the 14 media combinations, the optimum responses were observed on 1 mg/l
Kn, in the case of G3 genotype, on 2 mg/l Kn with G2
genotype, on 1 mg/l BAP with G4 genotype and on 2 mg/l
BAP with S34 and S13 genotypes. S13 itself exhibited the
highest sprouting percentage and shoot growth compared to
the other genotypes. The genotype G3 has been identified as
suitable for drought prone areas.
