“…Comparison of the relative tolerance (measured as the survival of seedlings in a salinized hydroponic system) of seven wild species of rice and the two cultivated species, O. sativa and O. glaberrima, found that none of the wild species were as tolerant as the most tolerant of the cultivated lines of O. sativa tested, such as Nona Bokra [89]. Of the remaining ten or so species within genus Oryza, there is no information concerning their tolerance to salinity, except for Porteresia coarctata Takeoka which is a native of salt-marshes around the coasts of the Bay of Bengal, and can grow in as high as 20% seawater without any adverse effect on growth [90].…”

“…Shannon (1985) suggested that there is evidence of a genetically complex trait, showing heterosis, dominance and additive effects. In diallel analysis the effects of salinity on the seedling stage and on sterility suggested both additive and dominance effects, some with high heritability (Moeljopawiro and Ikehashi, 1981;Akbar et al, 1985). Another inheritance study for salinity tolerance in rice by Mishra et al (1998) also inferred polygenic inheritance.…”

“…Akbar et al (1985) reported that the dry matter weight of rice seedling under salt stress was affected by at least two groups of genes with additive effect, and no epistatic effect was detected. Thi Lang et al (2010) reported that a dominant gene controls resistance to salt stress in the allelism test.…”

“…The estimates indicate that the salt affected soils will constitute nearly 16.2 m ha area in the country by 2050 (CSSRI-Vision 2050) without technological interventions, compared to the current estimate of 6.74 million ha. Growth and yield components of rice are severely affected by salinity (Akbar et al, 1986). Hence, there is an urgent need to convert high yielding mega popular varieties as saline tolerant variety to meet out the alarming soil related problems for rice cultivation.…”
