Kerala state's rice consumption is predicted to be between 3.5 and 4 million tons per year, but production just a sixth of this. In order boost the production, attention must paid traditional growing techniques. Thus, there need understand Pokkali cultivation method used in Kerala. The style farming Kerala's acidic, saline soil distinctive way cultivation. A native historic salt-tolerant type c...

DNA methylation has been referred as an important player in plant genomic responses to environmental stresses but correlations between the methylome plasticity and specific traits of interest are still far from being understood. In this study, we inspected global DNA methylation levels in salt tolerant and sensitive rice varieties upon salt stress imposition. Global DNA methylation was quantifi...

Globally, over one-third of irrigated land is affected by salinity, including much of the land under lowland rice cultivation in the tropics, seriously compromising yields of this most important of crop species. However, there remains an insufficient understanding of the cellular basis of salt tolerance in rice. Here, three methods of 24Na+ tracer analysis were used to investigate primary Na+ t...

Rice is an important crop that is very sensitive to salinity. However, some varieties differ greatly in this feature, making investigations of salinity tolerance mechanisms possible. The cultivar Pokkali is salinity tolerant and is known to have more extensive hydrophobic barriers in its roots than does IR20, a more sensitive cultivar. These barriers located in the root endodermis and exodermis...

The genetics of’ salinity tolerance in rice was studied by visual scoring in parents F1 F2 and backcross generations of six crosses. Segregation analysis indicated partial dominance for salinity tolerance. Estimation of genetic parameters under epistatic model indicated the importance of additive effects in the inheritance of salinity tolerance. Highly significant additive type of gene action i...

Primary regenerants (1190) of a tall traditional salt tolerant rice cultivar pokkali were produced through in vitro culture from mature seed derived calli of fourth subculture. Out of 35000 SC2 regenerants, 26 promising lines with superior agronomic traits were chosen initially for evaluation. SC3 and SC4 generations were stringently evaluated under hydroponics with excess salt stress as well a...

Identification of the seed varieties is essential in quality control and high yield crop growth. The existing methods varietal identification rely primarily on visual examination DNA fingerprinting. Although pattern fingerprinting allows precise classification but fraught with challenges such as low rate polymorphism amongst closely related species, destructive method analysis a huge cost invol...
