Abstract (2. Language):
A field experiment to study the genetic variation in M1 Gamma irradiated
population of two varieties of sunflower (Helianthus annuus L.) was conducted at the green
house field area, University of Science & Technology Bannu, during crop season, 2011. The
Gamma irradiation has been enhanced nearly all the normal characteristics of the variety
Syngenta and variety High sun of sunflower. The control seeds of both these varieties
reflected emergence from 7-12 days but emergence were exceeded at 25 krad from 12-17
days in the irradiated seeds of these varieties. The plant heights were also enhanced and all
the irradiated plants of both the varieties have achieved above normal height and especially in
case of T2 treated Highsun variety. So for as the parameters like, Number of leaves per plant,
length and width of leaves are concerned were found positively enhanced. Profound
variability was observed in case of days to first flowering, number of sepals and petals in both
the varieties of sunflower. Although the parameters like diameter of flower’s head along with
number of seeds a reasonable enhancement was achieved.
