Our happiness

Our happiness may spring from what we have, but more of our happiness materializes from our peacefulness in accepting what we do not have.

May today God reward you for your gratefulness with beautiful love and wonderful fortunes.

Amen

GROWTH OF PEANUT LINES GENERATED FROM GAMMA RAY IRADIATION AGAINST POLYETHYLENE GLYCOL SOLUTION STRESS

ABSTRACT

The objective of this research was to evaluate the growth of peanut lines generated from Gamma ray iradiation against polyethylene glycol (PEG) solution stress. The peanut lines seeds of mutan M4 generation  were used in this experiment. Peanut plants of cv. “Local Bima” were also tested as control plant. The mutan and control peanut plants were planted on rice  hush charcoal medium. The peanut plants that 15 to 50 days old were watered with PEG 15% solution (0.41 Mpa osmotic potential = drought stress). Identification  of tolerant peanut  lines on PEG stress  were calculated with using drought  sensitivity index value (S) on observed parameter. Results of the experiment showed that peanut line G300 had a better vegetative growth (total plant dry weight, root dry weight and root lenght). Based on S value, peanut line G300, G250 and G200 were classified  as moderate tolerant and control plants sensitive to PEG solution stress.
