Not AvailableDue to complete submergence the seedling height increased and the root activity decreased. The increment of seeding height was greater in elongating , tolerant type Hatipanjari as compared to less-elongating, tolerant type FR 13A and susceptible cultivation , Tulasi, Reduction of root activity was. however in Tulasi, followed by Hatipanjari and FR 13A . Shoot dry weight either ceased (FR 13A) or Decreased (Hatipanjari and FR 13A ) in submerged conditions. Shoot dry weight and root activity gradually increased in air-adapted plants and enhanced the possibility of survivality of both tolerant and non tolerant cultivars. under complete submergence, the elongation , tolerant cultivar did not manifest better survivality thsn the susceptible cultivar.Not Availabl

Not AvailableAn experiment was conducted during 1995 to develop cultivars suitable for direct anaerobic seeding technology, ie germinated seeds are to be shown beneath the surface of flooded soil. For anaerobic direct wet seeding the genotype; 'CH 19' rice (Oryza sativa L.) was found to be better followed by 'T 1471' and 'FR 13A'. These genotypes could be utilized as parents in breeding programmes. Direct sowing with non-germinated seeds under anaerobic condition is observed to be illusive.Not Availabl
