  • Screening methods for salinity tolerance: a case study

    01/06/2003· Fast and effective glasshouse screening techniques that could identify genetic variation in salinity tolerance were tested. The objective was to produce screening techniques for selecting salt-tolerant progeny in breeding programs in which genes for salinity tolerance have been introduced by either conventional breeding or genetic engineering. A set of previously unexplored tetraploid wheat

    Supported hydroponic method for screening plants for salinity tolerance. Pots are filled with quartz gravel, 144 pots per tank, and the tanks are subirrigated every 30 min with nutrient or saline

  • Salinity tolerance in plants: Breeding and genetic engineering

    source, target plant and type of gene product are summarized Conventional breeding approach in supplementary Table. S1. Plant breeding has been used since long for the production of high yielding and stress tolerant crops. Plant breeders have used genetic variation in crops, at intraspecific, interspecific and intergeneric levels to produce salt tolerant lines. Lots of salt tolerant crop

  • Breeding for salinity tolerance in rice

    The most relevant strategy was the genetic manipulation of plants to breed salt-tolerant varieties. Efforts to breed for salinity tolerance had been attempted but the progress was slow due to limited knowledge of the genetics of salt tolerance; inadequate screening and selection methods, and poor understanding of interaction of salinity and environments. Rice was moderately sensitive to

  • Breeding for salt tolerance ~ Breeding & Plant Genetics

    29/10/2013· The challenge in breeding for salt tolerance is how to measure salinity tolerance. Screening is commonly based on growth of plants under salt stress. Two distinct mechanisms exist for salinity . tolerance: Tolerance to the osmotic effect of the saline solution. Tolerance to the cytotoxic effect of Na entering the cell. In addition, the salt-specific nature of the soil saline. Screening for

  • Salinity tolerance and breeding strategies on soybean

    08/06/2016· Salt-affected soils can be divided into saline, saline- sodic and sodic, depending in salt amounts, type of salts, amount of sodium present and soil alkalinity. Each type of salt-affected soil will have different characteristics. Soil salinity is one of the important abiotic components that frequently have critical effects on crop growth, productivity and quality Iran salt affected soil China

  • Benefits and limitations in breeding salt-tolerant crops

    The plant breeding approach to pro- ducing salt-tolerant crops has two limi- tations screening procedures can be developed. Ultimately, breeders may be able to develop simple evaluations based on the physiological mechanisms for salt toler- ance. Some tolerant plants accumulate ions such as sodium in leaves and other tissues; others have ways of preventing ions from entering the plant

  • WL Alfalfas Breeding Alfalfa for Salt Tolerance

    Breeding Alfalfa for Salt Tolerance As more salt-tolerant alfalfa varieties are developed, managing high soil salinity should become increasingly achievable for forage producers in the western U.S. Highly saline soils have been a thorn in the side of alfalfa producers in arid regions of the United States for years. Soils that are high in salt can limit alfalfa yields, and have a negative

  • Salinity- mitigation plant stress

    The classical breeding approach is to (1) screen collected germplasm for salinity tolerance, (2) cross the identified tolerant types with the desired cultivars and (3) selecting the desired plant types having salinity tolerance as well as other desirable traits from the advancing and segregating generations. By exploiting the naturally occurring genetic variability that exists within a species

  • Physiological parameters of salt tolerance during

    Nonetheless, plant breeders have successfully improved salinity tolerance of some crops through conventional selection and breeding techniques. There is a consensus among researchers that selection is more convenient and practicable if the plant species under test possesses distinctive indicators of salt tolerance ( Roychoudhury and Chakraborty, 2013 ).

  • Breeding alfalfa for salt tolerance Progressive Forage

    31/12/2015· An aggressive breeding effort began in 2010, evaluating and screening alfalfa plants for salt tolerance in actual field conditions. FGI uses three methods for testing new salt-tolerant alfalfa varieties: 1. Greenhouse testing: Salt germination tests are conducted, which measure alfalfa seed germination under moderately high salt conditions.

  • 4.1 Salt tolerance

    Reproducible differential manifestation in plants with respect to their morphological, physiological or biochemical parameters in response to salt stress qualifies for a reliable screening criterion. Reliable screening is an integral part of any successful breeding programme. Salt related problems seldom occur in isolation and are coupled with many associated problems. Complexity of the salt

  • PROTOCOL: Salt tolerance screening in rice using hydroponics

    breeding. Screening for salt tolerance in the field is difficult as soil salinity is dynamic: the level of salt varies both horizontally and vertically in the soil profile and changes with time. These environmental perturbations are overcome by testing in a hydroponics system in a stable environment. Abiotic stress tolerance, especially salinity stress is complex because of variation in
