Abstract:
Considering the status of India, there is 5.0 million hactre/16.1 million hectare are affected pretentious by submergence. There are either flash floods with full submergence ranging water depth from 25-50cm or deep flooding with more than 50cm stagnated water for some weeks. The study was carried out at the Research Farm of ‘Tirhut College of Agriculture, Dholi, Dr Rajendra Prasad Central Agricultural University’, Bihar. A total number of 24 genotypes are taken for the experiment in RBD design having three replications of each treatment. The lower difference value between PCV and GCV indicating lower influence of environment. High heritability coupled with high genetic advance as percent of mean were recorded maximum for Crop growth rate at 30days after sowing followed by Crop growth rate at 15days after sowing, Days to 50% flowering, Seedling vigour, indicates there may be presence of Additive Gene Action and direct selection for these traits will be effective. Low Heritability coupled with high Genetic Advance found in Scoring for Submergence Tolerance indicates there may be presence of Additive Gene Action and selection will be effective.
