I am interesting to know that what are the physiological or biochemical traits to correlate with grain yield or any other growth stage? or any possibility to correlate with each other? Suppose i have estimated following attributes
chlorophyll
Proline
Glycine betaine
Total soluble sugars
Total phenolics contents
Anthocyanins
Sodium and potassium contents etc..
Regards
Wajid , i feel , simple exercise of stepdown correlation and regression analysis will let you know the most critical component affecting the grain yield , by taking yield on Y-axis and all components as X1...Xn . Thats the simplest technique to arrive at what you want ...
The most important traits are Praline ,Increase in proline content of wheat causes increase in tolerance to salinity ,or increase in proline causes increase in yield under saline condition ,or proline decrease the -ve effect of salts or decrease in salinity stress. TSS in wheat plant has similar effects.
Wajid , you can bring more precise information , if you carry out the stepdown regression analysis at different growth stages or else you can undertake Principal component analysis as well. this will give you very clear picture , at which stage , which parameter is dictating the grain yield under saline conditions.
