Abstract


ACM 16 (AC 2836/Jeganath) was an introduced genotype in to Tamil Nadu from Central Rice Research Institute, Cuttack through Directorate of Rice Research trials. It is short statured with high tillering ability and non-lodging culms. It matures in 120- 125 days. It tolerates the cold stress at all stages of growth and produced low spikelet sterility (7.8%) as compared to IR.20 (13.7%) in cold stress areas. ACM 16 has recorded a mean grain yield of 5882 kg/ha under cold stress condition. It is resistant to blast, sheath rot, white backed planthopper and grain discoloration and moderately resistant to brown spot and brown planthopper. Hence it was released as a new rice variety MDU 4 for cold stress areas of Madurai, Salem and Dharmapuri Districts.
