Rice (Oryzae sativa L.) is one of the most important cereal crops on which an ever-increasing population is dependent for food globally. However, constraints such as infectious diseases; brown spot transmitted by seed and wind reduced its production and productivity. This study was, therefore, conducted with the aim of screening of rice resistant lowland rice pipelines under natural infestation rain-fed conditions in Fogera plains of Amhara region, Ethiopia. A total of forty-nine lines were screened for their resistance against brown spot in the field with a simple lattice design including two susceptible varieties namely, X-Jigna and Gumara, and two resistant varieties, Shaga and Wanzaye. Sixteen genotypes showed highly resistant reactions for Bipolaris oryzae, and six of them including susceptible checks were highly susceptible. Amongst the highly resistant genotyp.. View more»
