Stem rust is a devastating disease in barley that is caused by a fungi (Puccinia graminis f. sp tritici, Eriks. and E. Henn). The disease has been controlled for quite some time due to the presence of cultivars carrying the resistant gene Rpg1. It has been effective in controllin...

Effects of Induced Mutagenesis on Agronomic Traits in Barley (Hordeum vulgare L)

I. J. Obare, M. G. Kinyua & O. K. Kiplagat · Journal of Experimental Agriculture International · 2014

Induced mutagenesis has been extensively used to improve main crop species, particularly cereals including barley (Hordeum vulgare L).The main strategy in mutation-based breeding is to upgrade the well adapted plant varieties by improving a few desirable major traits such as yiel...
