Identification of Resistance Sources to Barley Yellow Rust (Puccinia striiformis f. sp. hordei) in India
Main Article Content
Abstract
One hundred and twenty seven genotypes of barley from the various centres of the All India Coordinated Wheat &
Barley Improvement Project (AICW&BIP) were evaluated by artificial inoculation in the field for two consecutive
years (2009-10 and 2010-11) to identify new sources of resistance to yellow rust (Puccinia striiformis f. sp.
hordei). The same set of genotypes was also evaluated against five individual races, 24, 57, G, Q and M at the
seedling stage during 2009-11 in the greenhouse under controlled conditions. Based on both seedling and adult
plant evaluation 10 genotypes (BHS392, DWR88, JB187, JB206, PL844, RD2786, RD2787, RD2803, RD2804
and VLB119) were found resistant across the five races of yellow rust in India. These new sources of resistance
to multiple races of yellow rust would be useful in resistance breeding programme in India
