Association between berry characters and Solasodine content of solanum khasianum.

Correlation between number, grren weight, dry weight and solasodine percent of berry of the treated and control plant progenies in second generation raised from X-rayed (5 KR, 7.5 KR, 10 KR, 12.5 KR and 15 KR), EMS-treated (0.5%, 0.75% and 1% solution in PO (4)-buffer) and untreated dry seeds of Solanum khasianum Clarke revealed that only the numbers of large and small berries had significant correlation with solasodine percent. Correlation between induced variations (CV%) in these characters indicated that selection on berry characters through M (1) and M (2) generations was effective. Dispersion (due to mutagenesis) in the three berry characters have created the base for progressive selection for high solasodine yielders.
