Quality of seed material of barley tw type mutants according to susceptibility to micromycetes after treatment of previous generation with salicylic acid

Anotacija

A peculiarity of the tweaky spike (tw) allelic barley mutants is an increased frequency of moldy germinating grains. In the present work, this peculiarity has also been established for the branched ear (be) barley mutants. Unexpectedly, it has been determined that seed material quality can be improved by treating the previous plant generation with salicylic acid. This effect of salicylic acid is new, and employment of such mutants as tw or be enables to research immunoresistance induction by other inducers. Keywords: induced immunoresistance, salicylic acid, effect on next generation, usage of mutants
