In the present study Isoetes coromandelina ssp. thanensis S.K. Shukla, S.K. Singh, P.K. Shukla, N.K. Dubey, H. Khanam & G.K. Srivastava a micro endemic new subspecies is described from the Than in Rajkot District of Gujarat state in coastal zone of India. Morphologically, the new subspecies is most similar to I. coromandelina ssp. coromandelina but differs in its microspore with levigate surface ornamentation and chromosome number 2n = 22 + 1. Different morphological features of I. coromandelina ssp. thanensis are discussed. Images and a distributional map are also provided. In the present study, we made a correlation between microspore ornamentation and ploidal status at the infra-specific level which helpful in taxonomy of closely related taxa. © 2017, College of Life Science.

AstractAn effort has been done to assess the effect of combined treatment of various doses of gamma rays along with 0.6% EMS on JSF-I and JST-7 varieties of safflower. The combined effect may develop some different set of characteristics that cannot be achieved when these mutagens are used separately. An attempt has been made in this paper to study interaction of gamma rays and EMS on morphology of two varieties of safflower.
