Genetic improvement of pyrethrum (Tanacetum cinerariifolium Sch. Bip.) through gamma radiation and selection of high yield stable mutants through seven post-radiation generations.

Abstract excerpt

PURPOSE: To increase the size of the flowers for easy plucking, flower yield, pyrethrins content (%), and elite mutant selection in pyrethrum. MATERIALS AND METHODS: To increase pyrethrum production and acclimatize in north Indian plain condition, a genetic improvement program was undertaken to widen the range of variations for size and yield of flowers and pyrethrins content (%) in pyrethrum crop. Pyrethrum...
