In order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars Khazar, high yielding and resistant to blast disease and Daylamani Tarom, with good cooking quality in 1990. Forty pure lines were selected and compared for high grain yield in 1996. Ten selected lines together with two check cultivars Dasht and Onda were tested in ...
the present investigation was carried out to examine virulence diversity among the 291isolates (seven populations) of rhizoctonia solani ag-1 ia causing sheath blight of rice by sclerotia production and pathogencity studies on four rice cultivars representing different observed disease reactions, using detached leaf inoculation method in conjunction with mycelia growth measuring. based on patho...
