Effect of system of rice cultivation on sheath rot disease and traits associated with grain yield under natural disease incidence in rice RIL’s
Keywords: recombinant inbred lines, sheath rot disease, aerobic rice, wetland rice, transgressants
AbstractOne thousand and ninety four recombinant inbred lines derived from BPT-5204 × HP-14 cross were evaluated for sheath rot disease incidence under field conditions under aerobic and wetland transplanted situation. The population exhibited significant genetic variability among the RIL’s in both systems of rice cultivation. Response of the disease in both conditions was non-significant indicating that influence of planting system did not make any significant difference for this disease. Transgressive segregants were observed for yield attributing traits but not for sheath rot resistance. RILs HPR-1270, HPR-1416, HPR-212, HPR-260, HPR-1506, HPR-1407, HPR-1380 and HPR-312 in aerobic system and HPR-285, HPR-2129, HPR-978, HPR-702, HPR-94-2, and HPR-1514 in wetland system were found superior for both grain yield and sheath rot resistance. These genotypes could be evaluated further in large scale field trials for developing resistance varieties with superior grain yield.
