Sources of resistance in the existing breeding germplasm will be identified for incorporation in the elite cultivar/variety
In order to identify new sources of resistance to net blotch, a FIGS subset consisting of 96 barley accessions was screened with a mixture of 20-isolates of net blotch collected from different agro-climatic regions of ...
Use of hotspots for screening of each disease / pest
A FIGS subset of yellow rust of 298 accessions was screened in the field in Durgapura, Jaipur (India) with artificial inoculation with an inoculum consisting of a mixture of 5-pathotypes. Based on the area under disease ...
Responses of differential barley genotypes to Moroccan isolates of Pyrenophora teres f. teres
Barley net blotch, caused by Pyrenophora teres f. teres (Ptt), is one of the most important foliar
diseases in Morocco. The disease causes appreciable yield losses under favorable environmental
conditions. To identify ...
Genome wide association study (GWAS) of resistance to barley spot blotch in South Asia
Spot blotch, caused by Cochliobolus sativus (anamorph: Bipolaris Sorokiniana) is one of the important
foliar diseases of barley in South Asia. However, limited information on genetic resistance of spot blotch
resistance ...
Genome wide association studies of barley net blotch resistance in Morocco
Net blotch of barley caused by Pyrenophora teres f. teres (net form) and Pyrenophora teres f. maculata
(spot form) are important foliar diseases of barley crop worldwide. In Morocco, the yield losses can reach
up to 35% ...
Genome-wide association study of stripe rust (Puccinia striiformis f.sp. hordei) resistance in a world collection of barley (Hordeum vulgare L.)
Stripe rust (Puccicina striiformis f.sp. hordei) (PSH) is one of the major diseases that causes significant yield losses of barley (Hordeium vulgare L.) worldwide. Frequent breakdown of resistance genes and emergence of ...
Molecular and phenotypic diversity of ICARDA spring barley (Hordeum vulgare L.) collection
Plant breeders are interested in using diverse genotypes in hybridization that can segregate for traits of importance with possibility of selection and genetic gain. Information on molecular and agro-morphological diversity ...
Survey and disease monitoring in focal countries
The cropping season of 2015-16 has been exceptionally dry with severe drought. During the disease survey occasionally low incidence of net blotch, spot blotch and scald was observed.
It is important to note that the ...
Novel sources of resistance to stripe rust in ICARDA barley germplasm
Stripe rust of barley (Puccinia striiformis Westend. f. sp. Hordei) occurs worldwide and host resistance is
the most economically and environmentally appropriate option as the use of fungicides is not very common
in low ...
