The response of some spring barley cultivars grown in Finland to air-borne secondary infection by Bipolaris sorokiniana

REACTION OF BARLEY GENOTYPES TO Bipolaris sorokiniana

A study on response of 29 barley genotypes resistant to Bipolaris leaf blight (Bipolaris sorokiniana) was conducted to investigate the relationship of the components of resistance of 29 barley genotypes. Data on five components of resistance viz., infection frequency (number of lesions per plant), lesion size (mm), percent leaf area affected by lesion, percent necrotic area on leaf, and disease...

Variation in the response of barley cultivars to nirrogen fertilizer

reaction of some wheat cultivars to bipolaris sorokiniana the causal agent of common root rot

abstract common root rot induced by bipolaris sorokiniana, is one of the most important diseases of wheat. chemical control of this disease is difficult because of it is a soil-born pathogen, so that, application of other methods is useful to reduce disease level especially resistance cultivars. in this research, were examined reaction of some wheat cultivars and lines against common root rot i...
