IDENTIFICATION OF ADDITIONAL GENES CONFERRING RESISTANCE TO PUCCINIA_STRIIFORMIS WES~/,~~.§S OF BARLEY

Abstract

Barley culdvars, AbySflioiao 14(yr I), 1.5 (yr 3), and Cambrinus (yr 4) were genetitally .....ysed 4glIinst die 1adIan~G and 57 01' barley stripe rust. Two tester Ones, EB· 411 (PI I) and EB 43B. (}Is 4), with Imown siugIe gene for resistance to the races were used ... die enISleS to determiae relationship between die genes concerned ill stripe rust resistam:e present ia die material UDder study. De F, and Fl -nings were tested against botb tbe races. It ... l'ouad dull: AbySflioiao 14 possessed two dominaDt genes for resistance, one eadl eft'ecdve ...... races G and 57. 1'IIese genes for resistance are tentatively designated as Yr Ab. 14 land Ab. 14 1. Cv. 1.5 also pCJSIIElS(S two domilllmt genes for resistance to the races and dIese were .......ed as Yr 1.5 I and Yr 1.5 2. One domilllmt gene detected in die culdvar Cambrinus ... IIIIellc to the poe Ps I already Identified ill EB 410.
