Central Rainfed Upland Rice Research Station, Hazaribagh-825 301.
Evaluation of three hundred and five diverse rice (Oryza sativa L var. indica) genotypes against leaf blast led to the identification of 16 resistant and 28 tolerant cultures. Among 125 gora rices, only 10 showed tolerant reaction; none exhibited complete resistance. Six upland rice cultivars (Brown gora-HRC 14, Black gora-HRC 358, Kalakeri, Bhattadhan, N 22 and Dular) appeared to possess durable resistance. Quality analysis of 15 resistant donors suggested that some of them like Salumpikit, Bhattadhan, Kalakeri, CR 143-2-2, Brown gora HRC 14 and Khao Vano Veri possessed multiple desirable quality traits and hence should preferably be used in the varietal improvement programme to enhance the possibility of recovering segregants simultaneously improved for blast resistance and quality.
