Field evaluation and selection of resistance to rust diseases ( Puccinia Spp.) in wheat somaclonal variant lines [electronic resource].

Includes reference.

Forty somaclonal variant lines. produced from Sakho-69 wheat cultivar. using stepwise in vitro selection method, using p-fluorophenylalanine (PFP) as in vitro mutagenic agent for developing mutant lines resistant to rust diseases. were field evaluated, as well as their parent, at Sakho area, for grain yield and leaf rust (LR) severity as average coefficient of infection (ACI). The experiment was set up in a randomized complete block design. with two replicates due to small amount of seeds. There were highly significant differences among genotypes for grain yield. but there were no significant differences for ACI. Seventeen somaclones were selected for their low LR infection and high grain yield.
