To have knowledge development and its particular used use in grain salinity improve reproduction program, it is critical and you can vital to keeps particular, effective, reproducible and user phenotyping strategies for tests away from germplasm. Each one of these protocols possess characteristics also limitations and you will thus depending on the particular criteria and you will offered information, a combination of strategies is considered to possess research. It is also important to choose genomic regions according to phenotyping having salt stress indicator such as for instance fret sensitivity index and you may worry tolerance index hence take into account minimal yield avoidance lower than stress versus typical conditions (Pandit et al. 2010; Ali mais aussi al. 2013; Krishnamurthy mais aussi al. 2016) in place of stress overall performance alone.

Invasive approach

Certainly one of invasive methods, at least half dozen various other techniques are accustomed to make phenomics research to have connection knowledge, QTL mapping and you can assortment update program. These processes have widely become employed for genetics/QTLs mapping and introgression from salt tolerant genes for the grain varietal update (Gautam ainsi que al. 2014a, 2014b).

Saline hydroponics

cuatro.5 is handled (Singh mais aussi al. 2004). Salt is actually extra in substitute for manage wished quantity of salt be concerned. This method have advantages of even shipments from salts for uniform assessment, screening on seedling phase at any time lower than controlled standards and scope out of evaluating great number of lines really effectively with rapidity. But not that it methods have limits and since the fresh new sodium structure and you can background requirements away from definitely sodium affected grounds might be exactly mimicked. In addition to this, discover further constraints for example feasibility out of evaluating confined in order to seedling phase just and you can such as methodology is fairly technology and you can expensive.

Steel trays

Because of it means of phenomics study generation, rectangular metal trays are utilized which are full of salt troubled soil having planting the seedlings. Advantages of it strategy be more effective power over initial examination at seedling stage any moment, command over need amount of be concerned and large quantity of lines might be processed quickly. But not this technique has restrict given that sufficient and you will sheer soil breadth isn’t completely made certain. Also, research age group is actually restricted so you can seedling stage off small space only.

Ceramic containers

Inside, bullet porcelain pots of 20 otherwise 30 cm diameter, which have a strength off 8 or 16 kilogram floor are used to own tests. Examination can help you in the seedling phase. Advantageously, here we are able to handle the amount of salt fret and rapidity and lot away from contours kasidie. Plants can be easily uprooted at the wished increases phase getting psychological/mineral education. not, micro-environment regularity could be compromised when you are tests plethora of genotypes in different pots.

Micro-plots of land having roof

Within strategy, micro-plots was built using reinforced concrete concrete (RCC) structure and you will floor that have measurement of about six meters (length), step 3 meters (width) and you can step 1 meters (depth). This type of tanks are full of normal crushed that is generated forcibly sodic otherwise saline. Like approach provides benefit of are “crossbreed method” having effective regional handle together with shipping off directed amount of salts inside the a story. Besides this, it has got advantage of much more better simulation away from sheer criteria with need salt attention that is not toned down by water owed so you’re able to translucent sheet covered roof and you will keeping brand new edges offered to enable it to be the sun’s rays with the harvest. But not, the brand new floor become additional during these microplots away from exterior source have to have sheer nutrient structure when it comes to pick demands. After that it could be effortlessly utilized for examination plethora of outlines for reproductive phase threshold on account of alot more breadth off soil. Some associations from inside the India like ICAR-CSSRI, Karnal, NRRI, Cuttack, CCARI, Goa and you may CIARI, Vent Blair have established condition-of- ways micro-plots of land facility to have rice salinity functions. Even in the event, installing eg facility means a great deal more very first financial investments, it’s well worth-using.
