The two genotypes showed similar
callus induction potential under normal condition. However,
the two genotypes showed a varied callus induction
frequency when irradiated. Of the two genotypes tested,
FR43B showed a relatively higher frequency of callus
induction than FR13A. The % of callus induced in FR43B
was found similar (that is, 90%) under control and treated
(25 Kr) conditions. Similarly, in FR13A, the callus induction
frequency was higher when untreated as compared
to irradiated conditions. The callus induction potential in
both the genotypes increased with increase in the level of
irradiation from 20 - 25 Kr but it decreased drastically at
30 Kr (Figure 2).
